279 Operating Manual 1411.4060.32 ─ 04
Example: SOURce:POWer:LIMit:AMPLitude 10
or
:POW:LIM 10
limits the RF level to m10 dBm.
Usage: SCPI confirmed
[:SOURce<hw>]:POWer:LMODe <LevMode>
The command sets the RF level mode.
Parameters:
<LevMode> NORMal | LOWNoise | LOWDistortion
NORMal
The RF signal is output in the standard values of the instrument.
LOWNoise
A very low noise sinewave signal is output.
LOWDistortion
A very pure sinewave signal is output.
Example: POW:LMODE LOWD
sets the LOWDistortion mode. The instrument reduces distortions
of the RF signal to a minimum.
[:SOURce<hw>]:POWer:MANual <Manual>
In Sweep mode
(:SOUR:POW:MODE SWE
) the command sets the level for the next
sweep step in the Step sweep mode (
:SOUR:SWE:POW:MODE MAN
). Here only level
values between the settings
[:SOUR]:POW:STAR
and
[:SOUR]:POW:STOP
are per-
mitted. Each sweep step is triggered by a separate
:SOUR:POW:MAN
command.
As with the "Level" value entered in the "RF Level" menu, the
OFFSet
value is also taken
into consideration with this command.
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
Parameters:
<Manual> float
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 dBm
