Set the sweep time used for measuring each harmonic.
Factory Preset
and *RST: 200/resolution bandwidth (RBW)
Range: 10 ms to the maximum sweep time of the analyzer
Default Unit: seconds
Remarks: When set to 1 (Auto), the sweep time for measuring
each harmonic will be set to 200/RBW, where RBW is
the resolution bandwidth setting in Hz. When set to 0
(Manual), you can specify any sweep time within the
limits of the analyzer, with a minimum of 10 ms. This
sweep time is used only for the zero span measuring of
the harmonics, and not during the search for the
fundamental. In this case, the sweep time used will be
the sweep time set before the measurement began.

Turn On or Off Fundamental Zoom
[:SENSe]:HARMonics:ZOOM OFF|ON|0|1
[:SENSe]:HARMonics:ZOOM?
Turn on or off the fundamental signal zoom before the frequency count
occurs.
Factory Preset
and *RST: On
Remarks: When counter zoom is On, the measurement will zoom
in on the fundamental after the original marker search
and before the frequency count is executed. This
ensures the accuracy of the frequency count, and is
necessary when the starting resolution bendwidth is
very small or the starting span is very wide.
