SA (Spectrum Analyzer) Mode (Option 233–Mixed Analyzers)
SA Mode Settings
When FM Stereo /RDS is selected as the demodulation type, a Warning
message is displayed for a fews seconds at the start of the sweep; the
sweep is 30 to 50 seconds long.
The message reads:
"Warning: Slow Measurement. RDS Measurement in Progress."
