:OUTPut<hw>:AMODe <AMode>
Sets the step attenuator mode at the RF output.
Parameters:
<AMode> AUTO | FIXed
AUTO
The step attenuator adjusts the level settings automatically,
within the full variation range.
FIXed
The step attenuator and amplifier stages are fixed at the current
position, providing level settings with constant output VSWR.
The resulting variation range is calculated according to the posi-
tion.
*RST: AUTO
Example:
:SOURce1:POWer:ALC:STATe 1
:OUTPut1:AMODe FIXed
Manual operation: See "Mode" on page 152
:OUTPut<hw>:IMPedance?
Queries the impedance of the RF outputs.
Return values:
<Impedance> G1K | G50 | G10K
*RST: G50
Example:
:OUTPut1:IMP?
queries the impedance of RF output.
Response: 50
the impedance is 50 ohms
Usage: Query only
Manual operation: See "RF output impedance" on page 58
:OUTPut<hw>:AFIXed:RANGe:LOWer?
:OUTPut<hw>:AFIXed:RANGe:UPPer?
Queries the settable minimum/maximum value in mode :OUTPut:AMODe FIXed, i.e.
when the attenuator is not being adjusted.
See :OUTPut<hw>:AMODe on page 395
Return values:
<Upper> float
Increment: 0.01
Default unit: dBm
