[:SOURce]:ROSCillator[:INTernal]:ADJust[:STATe] <State>
The command determines whether the calibrated (OFF) or a user-defined (ON) adjust-
ment value is used for fine adjustment of the frequency. With STATe ON, the instrument
is no longer in the calibrated state. However, the calibration value is not changed and the
instrument resumes the calibrated state after switching the Adjustment State to Off.
Parameters:
0|1|OFF|ON<State>
ROSC:SOUR INT
selects the internal source.
ROSC:ADJ ON
activates use of a user-defined adjustment value.
ROSC:ADJ:VAL 1400
sets the adjustment value to 1400.
Example:
[:SOURce]:ROSCillator:SOURce <Source>
The command selects between internal and external reference frequency.
Parameters:
INTernal|EXTernal
INTernal
The internal reference oscillator is used.
EXTernal
An external reference signal is used. It must be input at the REF
IN connector at the rear of the instrument. The instrument is
informed of the frequency of the external reference signal by
means of the command
[:SOURce]:ROSCillator:EXTernal:FREQuency
on page 773.
<Source>
ROSC:SOUR EXT
selects the external source.
ROSC:EXT:FREQ 5 MHz
informs the instrument that the external reference has a frequency
of 5 MHz.
Example:
7.15.20 SOURce:SWEep Subsystem
This subsystem contains the commands for checking the RF sweeps, i.e. the sweeps of
the RF generators. Sweeps are always triggered, except for the MANual sweep mode.
The frequency sweep is activated by the command SOURce:FREQuency:MODE
SWEep, and the level sweep by the command SOURce:POWer:MODE SWEep. All
sweeps, including the LF sweep, can be set independently of each other.
