One-Button Measurement Functions
Example: SENS:SEM:RES
2.19.6 Optimize Ref Level
Sets the input attenuator and reference level to optimize the robustness of the
measurement, which is its freedom from errors due to input compression and log amp
range limitations.
NOTE There is always a minimum of 2 dB for PSA or 5 dB for ESA of attenuation
set to protect the analyzer input.
Key Path: Meas Setup
State Saved: Saved in instrument state.
Remote Command:
[:SENSe]:POWer[:RF]:RANGe:AUTO ONCE
Example: POW:RANG:AUTO ONCE
2.19.7 RRC Filter
Pressing RRC Filter turns the Root Raised Cosine filter on or off. This filter is the type
specified in the 3GPP W-CDMA standards. This parameter is only available when 3GPP
W-CDMA is selected as the Radio Std from the Mode Setup menu. If 3GPP W-CDMA is
selected, the rolloff value (alpha) for the filter will be initially set to 0.22 and T will be 260
ns. The rolloff value can be changed using Filter Alpha.
