Spectrum Analyzer (SA Mode)
SA measurements require NO calibration.
Check for a Compressed Measurement
1. Using a marker at the signal peak, make note of the
signal power level.
2. Increase the RF Attenuation level by 5 dB.
- If the signal level does NOT change, then NO
compression exists. This indicates that the signal is
in the linear region of the receiver.
- If the signal level DOES increase with more
attenuation, then compression DID exist. Set the
RF Attenuation value at the setting when further
increases no longer result in an increase in the
displayed power level.
Set RF Attenuation
1. Press Preset then Preset (Factory)
2. Press Mode then SA
3. Press Scale/Amptd then RF Atten
- Auto RF Attenuation is set by adjusting the Ref
Level.
- Man Change the RF Attenuation level manually.
Display up to four types of traces
SA settings are applied to all traces.
1. Press Trace 6 then Trace 1,2,3,4 repeatedly to select
a trace number to display.
2. Then State to select a trace type.
