3.8 Spurious Emissions Measurement
3.8.9.1 Sweep/Control
Accesses controls that let you operate the sweep and control functions of the
instrument, such as Sweep Time and Continuous/Single.
Sweep/Measure
Lets you toggle between Continuous and Single sweep or measurement operation.
The single/continuous state is Meas Global, so the setting affects all measurements.
The front-panel key Single/Cont performs exactly the same function

Compatibility
Notes
X-Series A-models had Single and Cont hardkeys in place of the SweepSingleCont softkey. In the X-
Series A-models, if in single measurement, the Cont hardkey (and INIT:CONT ON) switched to
continuous measurement, but never restarted a measurement and never reset a sweep
X-Series B-models have a Cont/Single toggle control instead of Single and Cont hardkeys, but it is still
true that, if in single measurement, the Cont/Single toggle control never restarts a measurement and
never resets a sweep
More Information
Continuous
Mode
The instrument takes repetitive sweeps, averages, measurements, etc., when in
continuous mode. If in average or Max/Min Hold, and the average/hold count
reaches the Average/Hold Num, the count stops incrementing, but the instrument
keeps sweeping
