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 291
[: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

[:SOURce<hw>]:POWer:STEP:MODE
on page 873.
Manual operation: See "Variation Step" on page 291
[: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 288.
Note: The level offset also affects the RF level sweep.
Parameters:
<Offset> float
Range:
-200 to 200
Increment: 0.01
*RST:
0
Default unit: dB
Level offset is always expreced in dB; linear units (V, W, etc.) are
not supported
Example: POWer:OFFSet 10
Sets the RF level offset to 10 dB
Manual operation: See " Offset " on page 294
