It reads shock recordings directly from NVGate measurement folders, computes SRS using the Smallwood (1981) recursive digital filter, and pushes results back into NVGate as live TCP result channels — all from a single application.

[[File:11_main_full.png|center|800px|thumb|'''Figure 1 — SRS Tool main window.''' Time signal with auto-detected shock zone (top right, yellow markers) and log-log SRS plot (bottom right). Three-channel triaxial measurement loaded: channels x, y, z.]]

== What makes SRS Tool unique==

SRS Tool is built around the idea that an engineer should go from raw measurement to qualification verdict in under one minute.

= Installation =
----
[https://partnerzone.digigram.com/s/NKAeEkA5ijFDZin SRS V1.3 here ]
Extract and launch the SRS_Tool.exe

( You need to select the '''folder''' of the signal measurement. )

= Main Tab =

[[File:04_left_panel_main.png|right|300px|thumb|'''Figure 2 — Main tab controls.''' From top: NVGate connection indicator, Signal folder, channel checkboxes with Reload, Calculation parameters, Output type selectors, Compute and Inject buttons.]]

== Signal ==

Click '''Select signal folder…''' to open a folder browser (default root: <code>C:\OROS\NVGate data\Projects</code>). Select the '''Measurement folder''' — channels are listed and the signal is plotted immediately.

== Channels ==

One checkbox per recorded channel, showing label, sampling rate, duration and unit:

<pre> ☑ x (25 600 Hz 13.86 s m/s²)
☑ y (25 600 Hz 13.86 s m/s²)
☑ z (25 600 Hz 13.86 s m/s²)</pre>

Channel labels (x, y, z…) come from the <code>Name</code> field set by the operator in NVGate at recording time.
Uncheck a channel to exclude it. '''↺ Reload channels''' re-reads files from disk after a new recording.

== Calculation parameters ==

{| class="wikitable" style="font-size:12px;"
! Parameter !! Description !! Recommended default
|-
| '''Frequency range''' || f_min to f_max of the SRS output || 1 Hz → 10 000 Hz
|-
| '''Q / Damping''' || Q factor or damping ratio ζ (linked: Q = 1/2ζ) || Q = 10 (ζ = 5 %)
|-
| '''Resolution''' || Octave subdivision: 1/3, 1/6, 1/12, 1/24 oct || 1/12 octave
|}

<div style="border-left:4px solid #1565C0; background:#e8f0fb; padding:9px 14px; margin:10px 0; font-size:12px; border-radius:0 3px 3px 0;">
'''Q = 10 (ζ = 5%)''' is the universal standard for aerospace shock SRS — MIL-STD-810H, ECSS-E-ST-10-03C, NASA-STD-7003A all specify this value. f_max is auto-clamped to Nyquist (f_s / 2).
</div>

== Output ==

; Type
: '''Acc''' — Acceleration SRS. Always available.   '''Vel''' — Pseudo-velocity SRS.   '''Disp''' — Pseudo-displacement SRS. (Vel and Disp require an acceleration input.)

; Curve
: '''Maximax''' — max(positive, |negative|). The standard curve required by most norms.   '''Positive''' — max tensile response.   '''Negative''' — max compressive response.

== Signal and SRS plots ==

[[File:05_signal_plot.png|center|760px|thumb|'''Figure 3 — Time signal plot.''' Three channels (x/y/z) overlaid. Yellow dashed lines mark the auto-detected shock zone. Drag horizontally anywhere on the plot to redefine the zone manually.]]

[[File:06_srs_plot.png|center|760px|thumb|'''Figure 4 — SRS log-log plot.''' Channels x (blue), y (orange), z (green). Each curve is the Maximax acceleration SRS over the detected shock zone. Q = 10, 1/12 octave, 1–10 000 Hz.]]

== Injecting results into NVGate ==

Click '''Inject into NVGate''' (or the duplicate button in the Advanced tab) to send all computed curves via the NVDrive TCP protocol as NVD REAL SPECTRUM channels:

* All SRS curves → separate TCP result channels
* X and Y axes: log scale (set automatically)
* Y axis: autoscaled
* All curves displayed in window '''SRS_Results''' of '''Layout1'''

NVGate channel naming convention:
<pre>SRS Acc Shock AbsMax: x
SRS Acc Shock AbsMax: y
SRS Acc Shock AbsMax: z</pre>

[[File:09_left_panel_adv.png|right|300px|thumb|'''Figure 5 — Advanced tab.''' Shock zone section (auto-detection parameters + manual Start/End override), Residual SRS option, preprocessing, and multi-axis SRSS / Envelope.]]

== Shock Zone ==

<div style="border-left:4px solid #e65100; background:#fff8f5; padding:9px 14px; margin:10px 0; font-size:12px; border-radius:0 3px 3px 0;">
'''The shock zone is auto-detected every time a signal loads''' — you normally do not need to touch these settings. Use manual override only to fine-tune the boundary.
</div>

=== Auto-detection ===

The detection algorithm:
# Compute a smoothed envelope: rolling mean of |signal| over a 3 ms window
# Trigger threshold = ''Threshold %'' × peak envelope
# Zone = first to last sample above threshold
# Expand by ''Padding ms'' on each side, clamped to signal bounds

{| class="wikitable" style="font-size:12px;"
! Parameter !! Effect !! Default
|-
| '''Threshold (% of peak)''' || Lower → wider zone; higher → core impact only || 5 %
|-
| '''Padding (ms)''' || Symmetric margin added on both sides of detected zone || 20 ms
|}

'''Padding example:''' shock detected at 8.055 s – 9.978 s with 20 ms padding → zone becomes 8.035 s – 9.998 s, ensuring ring-down is fully captured.

=== Manual override ===

Type '''Start''' and '''End''' (seconds, 3-decimal precision) — the yellow markers on the signal plot update immediately.
Dragging on the signal plot synchronises the spinboxes in return.

=== Residual SRS ===

Check '''Also compute residual SRS''' to run a second computation on the signal after the shock zone end. This captures the free-vibration decay required by MIL-STD-810H Method 517 and ECSS-E-ST-10-03C for fragility assessment. Residual curves appear on the SRS plot labelled "(residual)".

== Advanced Preprocessing ==

{| class="wikitable" style="font-size:12px;"
! Option !! Effect !! Typical use
|-
| '''Remove DC offset''' (N ms) || Subtracts the mean of the first N ms from the whole signal || Sensor bias, thermal drift
|-
| '''Noise floor''' (N ms) || Zeroes the first N ms || Pre-trigger noise before impact
|}

== Multi-axis Combination ==

Enabled automatically when ≥ 2 acceleration channels are loaded. Check one or both options before computing:

{| class="wikitable" style="font-size:12px;"
! Option !! Formula !! Display
|-
| '''SRSS''' — Square Root Sum of Squares || √(SRS_x² + SRS_y² + SRS_z²) || White dashed curve, Maximax only
|-
| '''Worst-case Envelope''' || max(SRS_x, SRS_y, SRS_z) at each frequency || Orange dash-dot curve, all types
|}

= Pass / Fail Tab =

[[File:07_left_panel_pf.png|right|300px|thumb|'''Figure 6 — Pass/Fail controls.''' Grouped limit curve library (30+ curves), user CSV option, scale factor, channel selector, Run button, and export buttons.]]

The Pass/Fail tab compares computed SRS against any normative or user-defined limit curve.

== Built-in limit curve library ==

<div style="border-left:4px solid #1565C0; background:#e8f0fb; padding:9px 14px; margin:10px 0; font-size:12px; border-radius:0 3px 3px 0;">
'''30+ normative curves are pre-programmed''' — select a standard from the grouped drop-down and run immediately. No other standalone SRS tool provides this library out of the box.
</div>

{| class="wikitable" style="font-size:12px;"
! Standard !! Curves included
|-
| '''MIL-STD-810H — Method 517''' || Near-field (< 0.3 m), '''Mid-field ★''' (0.5–1.5 m), Far-field (> 1.5 m), Gunfire, Tall vehicles

| '''RTCA DO-160G''' || Avionics Cat. A / B / C
|}

★ MIL-STD-810H Mid-field is the default — the most common qualification specification.

=== User-defined CSV ===

Select '''← User-defined (CSV)''', load a two-column file (Hz, g). Interpolation is log-log linear between breakpoints. Example:
<pre>10, 5     100, 50     2000, 50     10000, 50</pre>

=== Scale factor (dB) ===

Scales the limit curve before comparison: L_scaled(f) = L_nominal(f) × 10^(dB/20)

{| class="wikitable" style="font-size:12px;"
! dB || Multiplier || Typical use
|-
| +6 || ×2.00 || Conservative / tighter requirement
|-
| +3 || ×1.41 || Standard qualification margin check
|-
| 0 || ×1.00 || Nominal — no change
|-
| −6 || ×0.50 || Relaxed limit
|}

== Pass/Fail results ==

[[File:03_passfail_result.png|center|760px|thumb|'''Figure 7 — Pass/Fail chart.''' Three channels (x/y/z) vs MIL-STD-810H Mid-field limit (red dashed). All channels are well within spec: the margin subplot (bottom) shows 30–60 dB positive margin throughout the full frequency range.]]

=== Top panel — SRS vs Limit ===

Each channel plotted in a distinct colour. Limit curve: red dashed. '''Red fill''' = exceedance (SRS > limit). '''Orange fill''' = caution zone (0 ≤ margin < 3 dB).

=== Bottom panel — Margin (dB) ===

Margin M(f) = 20 × log₁₀( Limit(f) / SRS(f) )

{| class="wikitable" style="font-size:12px;"
! Colour !! Condition !! Meaning
|-
| style="background:#e8f5e9; color:#1b5e20;" | Green || M ≥ 3 dB || Well within specification
|-
| style="background:#fff8e1; color:#7a5200;" | Orange || 0 ≤ M < 3 dB || Caution — low margin
|-
| style="background:#ffebee; color:#b71c1c;" | Red || M < 0 dB || '''FAIL''' — exceedance
|}

=== Interactive cursor ===

Hover anywhere on either panel to see a floating readout snapped to the nearest frequency band, showing frequency, SRS value, limit value, margin in dB, and PASS/FAIL status. The readout border turns green, orange or red accordingly.

=== Verdict text ===

The result box below the chart shows global verdict, per-channel minimum margin, and the 10 worst exceedance frequencies. Example output:

<pre>PASS — Maximax SRS
Limit: MIL-STD-810H Meth.517 — Mid-field (0.5–1.5 m)

Per-channel result:
PASS x min +42.1 dB @ 500 Hz
PASS y min +38.7 dB @ 342 Hz
PASS z min +45.3 dB @ 1000 Hz

Worst margin (all channels): +38.7 dB @ 342.0 Hz

= Calculation Reference =

== Shock Response Spectrum ==

The SRS is the peak response of a bank of Single Degree Of Freedom (SDOF) oscillators, each with a different natural frequency f_n, driven by a common base acceleration x''(t):

<code>z''(t) + 2ζωₙz'(t) + ωₙ²z(t) = −x''(t)</code>

{| class="wikitable" style="font-size:12px;"
! Curve !! Definition !! Standard?
|-
| Positive SRS || max<sub>t</sub>[ ωₙ² z(t) ] || Supplementary
|-
| Negative SRS || max<sub>t</sub>[ −ωₙ²z(t) ] || Supplementary
|-
| '''Maximax SRS''' || max(Positive, Negative) || '''Required by most norms'''
|}

== Smallwood Recursive Filter ==

The Smallwood (1981) filter avoids step-by-step numerical integration, giving an exact discrete-time equivalent with coefficients computed once per frequency:

{| style="font-size:12px; font-family:monospace; border-collapse:collapse; margin:8px 0;"
|-
| style="padding:2px 10px;" | E = exp(−ζωₙΔt)    K = ωd·Δt    (ωd = ωₙ√(1−ζ²))
|-
| style="padding:2px 10px;" | b₀ = 1 − E·sin(K)/K     b₁ = 2(E·sin(K)/K − E·cos(K))     b₂ = E² − E·sin(K)/K
|-
| style="padding:2px 10px;" | a₁ = 2E·cos(K)     a₂ = −E²
|-
| style="padding:2px 10px; font-weight:bold;" | y[k] = b₀x[k] + b₁x[k−1] + b₂x[k−2] + a₁y[k−1] + a₂y[k−2]
|}

All N natural frequencies are processed in a '''single forward pass''' through the signal using NumPy broadcasting — typically 50–100× faster than a frequency-by-frequency loop.

== How the SRS Tool uses these curves ==

# Select a curve in the '''Pass/Fail''' tab.
# The tool interpolates the curve at the same frequency resolution as the measured SRS using log-log linear interpolation.
# Margin is computed point-by-point: '''Margin (dB) = 20 × log₁₀(limit / SRS)'''
# The overall result is PASS only if the margin is positive at '''all''' frequencies.

== Adding a custom curve ==

You can import your own limit curve via a two-column CSV file (frequency Hz, level g) using the '''Load CSV''' button in the Pass/Fail tab. The SRS Tool applies the same log-log interpolation as built-in curves.

💡 <strong>Key principle:</strong> The higher the sampling frequency, the more data to process — and the fewer SPUs are available per DSP board. SPU budget must be shared across all active channels and analysis types.
</div>
= Force DSP=

On force DSP (and normal DSP), the number of SPU change according to the max sampling frequency.

The more you have data to analyse (high sampling frequency), the less you have power computation (SPU).
We have:

{| class="wikitable"
|-
! Sampling Frequency (kHz) !! Number of SPU / DSP (Normal or Force)
|-
| 102.4 || 6
|-
| 65.536 || 9
|-
| 51.2 || 12
|-
| 32.768 || 18
|-
| 25.6 || 24
|-
| 16.384 || 36
|-
| 12.8 || 48
|-
| 6.4 || 96
|-
| 3.2 || 192
|-
| 1.6 || 384
|}

===FFT===
According to the architecture of force DSP, the SPU computation per channels is not linear. So we have the following table for real time SPU computation :

{| class="wikitable"
|-
! Number of FFT lines !! Normal DSP: SPU / channel !! Force DSP: SPU / channel
|-
| 401 ||1 || 0.33
|-
| 801 || 1.25 || 0.18 (yes<sup>1</sup>)
|-
| 1601 || 1.5 || 0.75
|-
| 3201 || 2 || 0.8
|-
| 6401 || 3 || 2
|-
| 12801 || 4 || 2
|-
| 25601 || 6 || 3.5
|}

Envelope: 401 lines : 2 SPU per channel on force DSP

Zoom: 401 Lines : 0.66 SPU per channel on force DSP.

1) Computing is not linear and FFT 801 lines is the most optimised for DSP

===Recorder===

{| class="wikitable"
|-
! Recorder Sampling frequency (Hz) !! Normal DSP: SPU / channel !! Force DSP: SPU / channel
|-
| 51200 or upper || 1 || 0.66
|-
| 32768 || 0.66 || 0.44
|-
| 25600 || 0.5 || 0.33
|-
| 16384 || 0.33 || 0.22
|-
| 12800 || 0.25 || 0.167
|-
| Else || 0.125 || 0.083
|}

===Octave===

{| class="wikitable"
|-
! Octave !! Normal DSP: SPU / channel !! Force DSP: SPU / channel
|-
| 1/3 || 3 || 1
|-
| 1/12 || 6 || 2
|-
| 1/24 || 12 || 4
|}

===OVA===

{| class="wikitable"
|-
! Normal DSP: SPU / channel !! Force DSP: SPU / channel
|-
| 1 || 0.25
|}

===TDA===

{| class="wikitable"
|-
! Normal DSP: SPU / channel !! Force DSP: SPU / channel
|-
| 3 || 1.5
|}

===SOA===

SPU computation for SOA is more complex because it depends of maximum speed, resolution and frequency. Also force DSP computation is not linear.

Force DSP will improve the SPU computation by reducing between 2.5 and 5 to compare with normal DSP.

(@20kHz - 401 lines, we need a maximum of 3 SPUs with normal DSP)

= Normal DSP=
SPU computation for normal DSP : OR34 V1 - OR35V1 - OR36V1 OR36V2 (normal DSP) - OR38V1 - OR38V2 (Normal DSP).

Because of the computation linearity, we simplify by saying: 1DSP = 12 SPU (no matter the sampling frequency). This allow a simplification for SPU computation. So we can deduce:

The overall acoustic levels analysis requires 1 SPU per channel at 20 kHz bandwidth. The number of required SPUs is directly proportional to the analysis bandwidth (i.e. the sampling frequency divided by 2.56).

__NOTOC__
[[File:O4_range Gamme O4 + OR10 + OR35 + OR36 + OR38.png|frame|left|FFT analyzers|alt=Analyzer acoustic vibration multichannel]]
The OROS series multi-function FFT analyzer is PC-based, high-performance, high reliability and easy to operate.

We have further increased the arithmetic processing speed and increased the real-time analysis capacity to more than 16 times that of the conventional model (OR20 series). An ethernet LAN cable is used as the interface.

In addition, the number of simultaneous recording channels in the frequency range (40 kHz) has been expanded to a maximum of 1000 channels and the dynamic range has been improved to 140 dB. These improvements allow a user to measure time signals over a wide frequency range simultaneously on multiple channels.

===Control Panel===
In addition, the OROS FFT spectrum analyzer is equipped with a control panel function that allows users to save frequently used measurement settings for quick access. By using this function, all settings can be changed on the [[NVGate_Control_Panel|control panel]]. For example, the following is the setting screen for a hammer test. By saving the input settings, threshold settings, and FFT analysis settings to the control panel as shown below, it is possible to make all the necessary settings quickly by only using the control panel.

[[File:control panel_test.png|700px|Software FFT settings|alt=Control easily the software]]

===Various filters can be applied to recorded signals & FFT analysis results===
Four types of filters: Low-pass filter, high-pass filter, band-bus filter, and band-stop filter, can be applied to the results of recorded signal and FFT analysis. By using a [[NVGate_Filter_Builder|filter]], it is possible to remove abnormal noise components from the recorded signal and perform processing such as reproducing the extracted abnormal noise components.

[[File:filter_fft.png|600px|Filter analyzer]]

===Extract arbitrary order components from the color spectrum graph in real time===

Any order component can be extracted in real time from the color spectrum graph.

[[File:extraction.jpg|Synchronous order analysis extraction|alt=order extraction on vibration software]]

* Measurement date and time
* Measurement conditions
* Measurement target
* Measurement site
* User
[[File:filter_project.PNG|550px|meta data on noise and vibration software NVGate|alt=Acoustic and vibration search function]]

===Fail judgment function as standard===
The [https://youtu.be/kx2HbcvfG_w pass / fail feature] of NVGate can be performed automatically after setting the desired bounds.

In the example below, a dialog is displayed when the product fails, but it is also possible to output a contact signal instead of the dialog.

[[File:fail_test.JPG|Pass/fail test on resonnance frequency impact hammer test|alt=Failed pass test on resonnance frequency test]]

===Automate post-analysis processing===

The same processing can be continuously performed for record files measured multiple times. By using this function, it is possible to automate the generation of reports, and it is possible to generate the same number of post-analysis results and EXCEL-based reports as record files with one click. Processing that used to take more than a week can now be done in a few hours.
