SYSTem:ROSCillator:SOURce INTernal|EXTernal
SYSTem:ROSCillator:SOURce?
Parameter
Typical Return
INTernal|EXTernal, default INTernal
INTernal, or EXTernal
Use the external reference oscillator source: SYSTem:ROSCillator:SOURce EXTernal
EXTernal:
instrument uses signal on the rear-panel
10 MHz In
connector as reference, and
generates an error if this signal is absent or the instrument cannot lock to it. In such error cases,
instrument output continues, but the frequency will be unstable.
INTernal:
instrument uses the internal reference oscillator and ignores the signal at the
10
MHz In
connector.
5.2.24 SOURce Subsystem
Subsystems Using the Optional SOURce Keyword
Because SOURce subsystem commands are often used without the SOURce keyword, these
commands are listed by their individual subsystems, below:

SOURce<n>:SWEep:HTIMe <seconds>|MINimum|MAXimum
SOURce<n>:SWEep:HTIMe? [MINimum|MAXimum]
Sets number of seconds the sweep holds (pauses) at the stop frequency before returning to the
