====The "Analyses" tab====
[[category:NVGate]]
In this tab, the software gathers the analyses controls. Each group corresponds to a plug-in analyzer. The content of this tab depends on the purchased optional plug-in.

In this tab, the software gathers the analyses controls. The content of this tab depends on the purchased optional plug-in.


==Front-end group==


[[File:Analyses_Front_end_2022.PNG|160px]]


=====Monitor group=====
Control/command the Front-end sampling high frequency and low frequency.
The Monitor plug-in offers simple and powerful ways to monitor the measured signals. This 4 channels plug-in runs independently from the general analyzer status (running/Paused/stopped) with the capability of swapping connected channels at any time.
''Note: The plug-in analyzer and the recorder can reduce their respective bandwidths independently. This setting fixes the acquisition time accuracy and fixes the max signal bandwidth.''<br>


[[Image:Reports_Tools_Ribbons_378.png|framed|none]]
See [[NVGate_Front_End#Input_settings|Front-end/inputs settings]] for details.


The second capability of the monitor is to extract statistical component of the signal in a specific bandwidth. Extracted levels can be used for triggering and waterfall references.
==Player group==


The monitor runs its analyses on a specific processor (DSP) allowing a totally independent computation for the regular analyses.
