==Signal sources==
NVGate<sup>®</sup>/OROS 3-Series multi-analyzers platform can process signal coming from different sources. These sources are detailed in this section as modules.
===Front-end===
The front-end module gathers the different input and output settings available in the instrument unit. In addition, the front-end module generates virtual signals (synthesized) when running the office mode (no unit connected to the PC) which is useful for set-up.

===Recorder / Player===
OROS 3-Series/NVGate instruments feature a recorder and a player module that allows users to:<br>
* Record time domain signal, torsional inputs, trigger and parametric input.
* Export or import time domain files.
* Playback time domain files on analyzers outputs during analysis
* Listen recorded tracks on the PC speakers.
* Post-analyze time domain files in the available plugs-in.
===Recorder===
The recorder module memorizes time domain signal into files located on 3-Series analyzer HD, Mobi-Disk<sup>TM</sup> or PC HD. This is available on 2 different modes:<br>
* '''On-line record''', the chosen inputs (Dynamic, ext. sync, parametric) are recorded at selected sampling frequency during acquisition. Real-time analysis is available simultaneously.
* '''Time and tracks split''', the chosen recorded tracks (from signal file) are played back in the recorder using the post-analysis mode. The sampling frequency, duration, and/or track arrangement can be changed.

===Player===
The player module plays the recorded signal files. This is achieved following 2 different ways:
* '''Post-analysis''', the player tracks take place of the corresponding inputs (Dynamics, Ext. Sync and parametric) to be processed by the plug-in analyzers, recorder, trigger and tachometer
* '''Playbacks''', the recorded dynamic input are generated on the instrument outputs simultaneously with standard analysis of the inputs.

The CTE option combines 2 actual tachometers with math to generates a calculated angular velocity (new tachometer). It covers various unreachable rotating parts and more specially the CVT gear chain measurements. The combined tachometers are made available as standard tachometer. This option operates real-time computation and operations are possible on-line or post processing.

==General purpose analysis==
The following modules are available as standard features of NVGate<sup>®</sup> software platform; they feature additional analysis capabilities to regular plug-in analysis module.
===Monitor===
The monitor is an independent (dedicated processor) module that processes continuously FFT analysis on 4 channels at the maximum available bandwidth. The aim of this module is to monitor in both domains (time and spectral) 4 inputs and to compute basic indicators for monitoring and triggering purpose.

==Shared resources==
The following resources are available for each plug-in analyzer (when it is compatible). For example once a trigger is activated it can be applied to FFT and SOA: Then modifying the trigger setting in the resources will apply on all corresponding plug-in.
===Triggering===
Each plug in analyzer (and recorder) can be started, stopped or triggered (new block) with events defined in the Event module.

==Notes==
The above specifications describe all the guaranteed capacities and performances of the NVGate V8.00 software installed in a PC running Windows 7 pro (recommended configuration). Functionalities may change depending on operation mode (connected to a 3-Series unit or office). Plug-in analyzers, options and channel number availability depend on purchased options.
The instruments hardware are described separately in the "Instruments specifications" data sheet for OR34 & OR35 and OR36, MP & OR38.
OROS reserves the right to modify the specifications without notification.
