One-Button Measurement Functions
2.3.5 Meas Type
Press Meas Type to specify the reference for the measurement, either Total P wr Ref or PSD
Ref. Relative values can be displayed referenced to either the total power (Total Pwr R ef) or
the power spectral density (PSD Ref) measured in the main channel.
Key Path: Meas Setup
State Saved: Saved in instrument state.
Factory Preset: Total Pwr Ref
History: Added with PSA firmware revision A.02.00.
Added with ESA firmware revision A.07.00.
Remote Command:
[:SENSe]:ACPower:TYPE PSDRef|TPRef
[:SENSe]:ACPower:TYPE?
Example: ACP:TYPE PSDR
ACP:TYPE?
2.3.6 Optimize Ref Level
Sets the input attenuator and reference level to optimize the robustness of the
measurement, in which it is free from errors due to input compression and log amp range
limitations. The input attenuator setting will not necessarily give the optimum dynamic
range, nor the optimum accuracy. No single setting can optimize both, and the optimum
setting often depends on the signal characteristics.
NOTE There will always be a minimum of 2 dB for PSA or 5 dB for ESA of
attenuation set to protect the analyzer input.
