3 VMA Mode
3.3 Monitor Spectrum Measurement
–
Electric attenuator only
–
Combination of Electric attenuator and Mechanical attenuator
when [:SENSe]:POWer[:RF]:RANGe:OPTimize IMMediate is executed.
Remote Command
[:SENSe]:POWer[:RF]:RANGe:OPTimize:TYPE EONLy | COMBined
[:SENSe]:POWer[:RF]:RANGe:OPTimize:TYPE?
Example
:POW:RANG:OPT:TYPE EONL
:POW:RANG:OPT:TYPE?
Dependencies Does not appear in the Swept SA, RTSA, Monitor Spectrum and Complex Spectrum measurements
Appears in the Waveform measurement in BASIC and 5G NR Modes
Preset
COMBined
State Saved Saved in instrument state
Pre-Adjust for Min Clipping
If this function is ON, it applies the adjustment described under "Adjust Atten for Min
Clipping" on page 1772 each time a measurement restarts. Therefore, in Continuous
measurement mode, it only executes before the first measurement.
In Dual-Attenuator models, you can set Elec+Mech Atten, in which case both
attenuators participate in the autoranging, or Elec Atten Only, in which case the
mechanical attenuator does not participate in the autoranging. This latter case
results in less wear on the mechanical attenuator and is usually faster.
See "Adjustment Algorithm" on page 578
Selection SCPI Note
Off
OFF
This is the default setting
On
ON
Available in Single-Attenuator instruments. For compatibility
with models that do not have an input attenuator, the ON
parameter is supported and mapped to COMBined
Elec Atten Only
ELECtrical
Selects only the electric attenuator to participate in auto
ranging. This offers less wear on the mechanical attenuator
and is usually faster
Elec+Mech
Atten
COMBined
In Dual-Attenuator models, this selects both attenuators to
participate in the autoranging
Remote Command
[:SENSe]:POWer[:RF]:RANGe:OPTimize:ATTenuation OFF | ON | ELECtrical |
COMBined
[:SENSe]:POWer[:RF]:RANGe:OPTimize:ATTenuation?
Example
:POW:RANG:OPT:ATT OFF
