To Turn Off Alternate Sweep
Alternate sweep is turned off when the analyzer is preset, but is
automatically activated with some dual channel measurements. The
alternate sweep feature sweeps and measures one channel at a time. By
disengaging this feature, you increase the sweep speed by a factor of two.

and look at the
softkey.
2. If ON is in capital letters, toggle the softkey to disengage the
alternate sweep feature (the softkey should appear
).
To Turn Off Markers and Marker Tracking
When markers are on, time is required to update the marker readouts.
Turning off markers can reduce sweep cycle time by up to 30 ms. When
the marker softkey menu is active, it too must be updated, adding up to
10 ms to the sweep cycle time.
Press
.
When marker tracking is on, the analyzer performs a search after each
sweep. Simple searches like

sweep. Lengthy calculations like
can add over 100 ms to
each sweep.

and look at the
softkey.
2. If ON is in capital letters, toggle the softkey to the OFF position.
