User Guide
CONFigure:DeviceUnderTestLength?
Usage:
CONF:DUTL?
Description: Queries the current DUT length (in meters) for Extended
Range
mode.
Response: Returns the current DUT length in meters.
CONFigure:SensingRANge
Usage: CONF:SRAN {sensingRange}
Description: In optional Sensing mode (page 48), sets the OBR Sensing
Range in the units set by CONF:XUNI (page 139).
[Note that CONF:INTW will perform the same function in
Sensing mode.]
Response: None.
Notes: The Sensing Range, along with the Sensing start
(CONF:INTS) or center (CONF:INTC) set commands,
defines the area that will be used for data capture and
retrieval commands such as FETC:MEAS. All frequency
domain values are based on this Sensing Range and start
or center. Setting the Sensing Range to 0 indicates that the
entire measurement area should be used for such
commands.
Setting the Sensing Range will cause the Sensing center
to be adjusted to match the new Sensing Range and the
Sensing start set using the CONF:INTS command.
CONFigure:SensingRANge?
Usage:
CONF:SRAN?
Description: Retrieves the OBR Sensing Range in the units set by

[The user may also use the CONF:INTW? command to
perform the same function.]
Response: Returns the OBR Sensing Range in meters.
CONFigure:INTegrationStart
