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 153
[: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 230
[:SOURce<hw>]:POWer:LBEHaviour <Behaviour>
Selects the level behavior at the RF output over time.
Parameters:
<Behaviour> AUTO | UNINterrupted | MONotone | CVSWr | USER | CPHase
UNINterrupted|MONotone
Uninterrupted level settings and strictly monotone modes.
CWSWr
Constant VSWR
*RST: AUTO
Example:
SOURce1:POWer:LBEHaviour AUTO
Manual operation: See "Setting Characteristics" on page 65
[:SOURce<hw>]:POWer:LIMit[:AMPLitude] <Amplitude>
Limits the maximum RF output level in CW and sweep mode.
It does not influence the "Level" display or the response to the query [:
SOURce<hw>]:POWer[:LEVel][:IMMediate][:AMPLitude].
