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

Example:
See [SENSe<Ch>:]ROSCillator[:SOURce].
[SENSe<Ch>:]SEGMent<Seg>...
This subsystem defines all channel settings for a Segmented Frequency sweep. A segmented sweep is
activated via [SENSe<Ch>:]SWEep:TPYE SEGMent.
The commands in the [SENSe<Ch>:]SEGMent<Seg>... subsystem do not accept the step
parameters UP and DOWN. Numeric values can be entered directly or using the DEFault,
MINimum, MAXimum parameters.
[SENSe<Ch>:]SEGMent<Seg>:ADD
Inserts a new sweep segment using default channel settings (Insert New Segment). The added segment
covers the frequency interval between the maximum frequency of the existing sweep segments and the
stop frequency of the entire sweep range.
Use [SENSe<Ch>:]SEGMent<Seg>:INSert to create a segment with specific channel settings.
<Ch>
Channel number. If unspecified the numeric suffix is set to 1.
<Seg>
Sweep segment number. Segment numbers must be sequential. If n segments
already exist, the added segment must have the segment number n+1.
*RST value –

Device-specific, no query.
