The specified value range is therefore only effective if
:SOURce:POWer:OFFSet
is set
to 0. The value range for other
OFFSet
values can be calculated using the following
formula:
Minimum level +
OFFSet
... Maximum level +
OFFSet
The keywords of this command are largely optional. Therefore, both the long and short
form of the command are shown in the example.
Parameters:
<Amplitude>
Minimum level ... Maximum level
The value range for the level setting varies according to the instru-
ment model.
The values are given in the data sheet.
Increment: 0.01 dB
*RST:
-30 dBm
Default unit: dBm
Example:
SOUR:POW:LEV:IMM:AMPL 15
or
:POW 15
sets the RF level at output A to 15 dBm.
Usage:
SCPI confirmed
[:SOURce<hw>]:POWer[:LEVel][:IMMediate]:OFFSet
<Offset>
Note:
The level offset is also effective for level sweeps!
The command specifies the constant level offset of a downstream attenuator/amplifier. If
a level offset is entered, the level entered with
:POWer
no longer corresponds to the RF
output level.
The following correlation applies:
:POWer
= RF output level +
POWer:OFFSet
.
Entering a level offset does not change the RF output level, but rather the query value
of
:POWer
.
For more information, see
chapter 5.3.6.1, "RF level vs. RF output level"
Only dB is permitted as the unit here. The linear units (V, W, etc.) are not permitted.
The keywords of this command are largely optional. Therefore, both the long and short
form of the command are shown in the example.
Parameters:

Range:
-100 dB to 100 dB
