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 704
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
:POW:RANG:OPT:ATT?
Notes The parameter option ELECtrical sets this function to ON in Single-Attenuator models
The parameter option COMBined is mapped to ELECtrical in Single-Attenuator models. If you
send COMBined, it sets the function to ON and returns ELEC to a query
For SCPI compatibility with models that do not have an input attenuator, the ON parameter is honored
and mapped to COMBined
Dependencies Only appears in Dual-Attenuator models with an Electronic Attenuator installed
In instruments with Dual-Attenuator model, when "Elec Atten" on page 1641 is OFF or grayed-out,
"Pre-Adjust for Min Clipping" on page 702 is grayed-out
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 OFF when Elec Atten is Disabled at preset, otherwise ELEC
State Saved Saved in instrument state
