Occupied Bandwidth Measurement
Mode
Control/Sweep
Accesses the sweep and sweep control settings that can be changed when using the OBW
measurement.
Sweep Time Query (Remote Command Only)
The sweep time value can be queried using the [:SENSe]:OBWidth:SWEep:TIME?
command. The OBW measurement is a Frequency Domain measurement only, so the
Sweep Time key is disabled (not available) in the OBW measurement.
Dependencies /
Couplings
Sweep time in non-zero span is coupled to RBW. As the RBW
changes, the sweep time is changed to maintain amplitude
calibration.
When Res BW is set to Auto, resolution bandwidth is
autocoupled to span. The factory default for the Span to RBW
ratio is approximately 106:1 when auto coupled. When Res
BW is set to Man, bandwidths are entered by the user, and
these bandwidths are used regardless of other analyzer
settings.
Preset 5 MHz, ON
State Saved Saved in instrument state.
Range 10 Hz to 200 kHz, plus bandwidths of 250 kHz, 300 kHz, and
1, 3, or 5 MHz

Notes In OBW measurement (Frequency Domain measurement), you
can only query the “sweep” time. Trying to set the Sweep Time
will generate a system error message
Dependencies /
Couplings
Sweep time is coupled to RBW and Span. It is also impacted by
the number of sweep points, so changing those parameters may
change the sweep time.
