Usage: Event
Manual operation: See "Readjust" on page 78
[:SOURce<hw>]:POWer:ATTenuation:PATTenuator <StepAttSel>
Selects the type of step attenuator used below 20 GHz.
Parameters:
<StepAttSel> MECHanical | ELECtronic
MECHanical
Uses the mechanical step attenuator at all frequencies.
ELECtronic
Uses the electronic step attenuator up to 20 GHz.
Options: R&S SMAB-B35/-B37/-B39, not available for R&S SMAB-B36S
Manual operation: See "Step Attenuator below 20 GHz" on page 215
[:SOURce<hw>]:POWer:ATTenuation:RFOFf:MODE <Mode>
Selects the state the attenuator is to assume if the RF signal is switched off.
Parameters:
<Mode> UNCHanged | FATTenuation
FATTenuation
The step attenuator switches to maximum attenuation
UNCHanged
Retains the current setting and keeps the output impedance
constant during RF off.
*RST: n.a. (factory preset: FATTenuation)
Example:
SOURce1:POWer:ATTenuation:RFOFf:MODE
FATTenuation
uses maximum attenuation when the RF output is turned off.
Manual operation: See "RF OFF Mode" on page 215
[:SOURce<hw>]:POWer:EMF:STATe <State>
Displays the signal level as voltage of the EMF. The displayed value represents the
voltage over a 50 Ohm load.
Parameters:
<State> 1 | ON | 0 | OFF
*RST: n.a. (factory preset: 0)
Example:
POW:EMF:STAT 1
Activates voltage level display.
Manual operation: See "Display Level as Voltage of EMF" on page 345
