[:SOURce<hw>]:POWer:STEP:MODE <Mode>
Defines the type of step width to vary the RF output power step-by-step with the com-
mands POW UP or POW DOWN.
Parameters:
<Mode> DECimal | USER
DECimal
Increases or decreases the level in steps of ten.
USER
Increases or decreases the level in increments, determined with
the command [:SOURce<hw>]:POWer:STEP[:INCRement].
*RST: DECimal
Example:
SOURce1:POWer:STEP:INCRement 2
SOURce1:POWer:STEP:MODE USER
SOURce1:POWer:LEVel:IMMediate:AMPLitude UP
Increasing the RF level with a step size of 2 dB
Manual operation: See "Variation Active" on page 62
[:SOURce<hw>]:POWer:STEP[:INCRement] <Increment>
Specifies the step width in the appropriate path for POW:STEP:MODE USER.
To adjust the level step-by-step with this increment value, use the command POW UP,
or POW DOWN.
Note: The command also sets "Variation Step" in the manual control, that means the
user-defined step width for setting the level with the rotary knob or the [Up/Down]
arrow keys.
Parameters:
<Increment> float
Range: 0 to 200
Increment: 0.01
*RST: 1
Default unit: dB
Example: See [:SOURce<hw>]:POWer:STEP:MODE on page 497.
Manual operation: See "Variation Step" on page 62
[:SOURce<hw>]:POWer[:LEVel][:IMMediate]:OFFSet <Offset>
Sets the level offset of a downstream instrument.
The level at the RF output is not changed.
To query the resulting level, as it is at the output of the downstream instrument, use the
command [:SOURce<hw>]:POWer[:LEVel][:IMMediate][:AMPLitude].
See "RF frequency and level display with a downstream instrument" on page 59.
