INIT_SWEEP_FSV

Start the sweep for the FSV. Requires a CONNECTION_FSV block at the start of the app to connect with the instrument. The VISA address will then be listed under 'connection'. This block should also work with compatible R&S network analyzers. Params: connection : VisaConnection The VISA address (requires the CONNECTION_FSV block). display : select Choose the trace display setting. continuous : bool Sweep continuously or not. Returns: out : TextBlob Display and sweep settings.

In this example, the Rohde & Schwarz FSV Signal Analyzer is used to view the FM radio range (86-110 MHz).

First 4 FSV nodes were added: CONNECTION_FSV, SWEEP_SETTINGS_FSV, INIT_SWEEP_FSV, and EXTRACT_SWEEP_FSV. A LINE node was also added. The VISA address was set for the 4 instrument nodes. The range of the signal analyzer sweep was set with SWEEP_SETTINGS_FSV (start = 86, stop = 110 MHz).

The nodes were then connected as shown in the image, and the app was run.
