[SENSe<Ch>:]ROSCillator[:SOURce] INTernal | EXTernal

Selects the source of the reference oscillator signal.

<Ch>

Channel number. This suffix is ignored in the ROSCillator subsystem and can be set to any value.

 

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.

*RST value

INTernal

 

SCPI, Command Types

Confirmed, command or query

 

Example:

ROSC EXT

Select external reference oscillator.

ROSC:EXT:FREQ?

Query the frequency of the external reference oscillator. The response is 10000000 Hz, i.e. the frequency of the external reference oscillator must be 10 MHz.

 

 

[SENSe<Ch>:]ROSCillator:EXTernal:FREQuency <numeric_value>

Specifies or queries the frequency of the external reference oscillator.

<Ch>

Channel number. This suffix is ignored in the ROSCillator subsystem and can be set to any value.

 

<numeric_value>

Frequency of the external reference clock signal. The frequency must be 10 MHz; any other setting is ignored.

Range [def. unit]

10 MHz [Hz].

*RST value

10 MHz
