RTSA (Real Time Spectrum Analyzer)
The RTSA is a real time, visual spectrum analysis tool for assisting in frequency coordination and selection of clean RF frequencies.
The RTSA can operate over the entire SpectraBand range (470 MHz to 1525 MHz). The RTSA trace represents RF signal level (in
dBm) on the vertical axis and RF frequency on the horizontal axis.
It has two modes of operation:
●
RTSA:
Real time analysis of the currently selected Tuning Band while maintaining reception of multichannel wireless
audio.
●
Scan:
Real time analysis of the entire or user-selectable portions of the 470-1525 MHz spectrum. All channel audio is
muted while scanning.
Typical Workflow
It is recommended to first use Scan mode to find the cleanest Tuning Band, then use RTSA mode to find the cleanest frequencies
within that Tuning Band. Once clean frequencies are found they can be assigned to receiver channels and their associated
NexLinked transmitters directly from the RTSA View.
The RTSA View can be displayed on a single screen (touch screen 4) or expanded across all 4 touch screens.
Single Screen RTSA View

From any RX View, show the single screen RTSA View on screen 4 by tapping the RTSA icon at the bottom of screen 4.

●
Change the vertical ‘dBm’ scale by tapping the up/down arrows.
●
Switch to the expanded RTSA view by tapping the center of the screen.
●
The single screen RTSA view is also displayed in the RF menu.
Expanded RTSA View
