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
SCPI, Command
Types
Confirmed, command or query
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
