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
2. Press Mode then
3. Press Scale/Amptd then
RF Attenuation is set by adjusting the Ref
Auto
Level.
Change the RF Attenuation level manually.
