SOURce<Ch>:...
This subsystem controls the power of the internal signal source and controls the output signals of the
instrument.
SOURce<numeric_suffix>:EXTernal<numeric_suffix>:ROSCillator[:SOURce]
INTernal | EXTernal
Switches between external and internal reference oscillator.
<numeric_suffix>
1 | 2 - The numeric suffixes are ignored.
INTernal
Select internal 10 MHz reference oscillator.
EXTernal
Select external reference clock. The frequency of the external reference clock
is specified via
[SENSe<Chn>:]ROSCillator:EXTernal:FREQuency

Device-specific, command or query
Example:
SOUR:EXT:ROSC EXT
Switches to external reference oscillator.
SOURce<Ch>:POWer<Pt>[:LEVel][:IMMediate][:AMPlitude] <numeric_value>
Defines the power of the internal signal source (channel power). The setting is valid for all sweep types.
<Ch>
Channel number.
<Pt>
Test port number of the analyzer. This suffix is ignored because the selected
channel power applies to all source ports used in the active channel.
<numeric_value>
Internal source power.
Range [def. unit]
–70 dBm to +20 dBm (to 0 dBm for R&S ZVL13 analyzers). The exact range
for all analyzer models is quoted in the data sheet [dBm]. UP and DOWN
