Zoom Points

In the Trace Zoom View of the Swept SA measurement, the Points key changes to Zoom Points
whenever the focus (thick green border) is on the bottom window. Zoom Points controls how many
points are displayed in the Zoom Window and hence indirectly controls the Zoom Span.

• Neither the knob nor the step keys can be used to change this value. If it is
tried, a warning is given.
• Grayed out in measurements that do not support swept
• Blanked in modes that do not support swept.
• Grayed out if Normalize is on; you can't change the number of sweep
points with Normalize on, as it will erase the reference trace.
• When Source Mode is set to Tracking, and Stepped Tracking is used (as
with option ESC), 201 source steps are used to achieve optimal speed. The
number of sweep points in the analyzer is then set to match the number of
steps in the source. When Source Mode is set to Off, the previous number
of points (the value that existed when Source Mode was Off previously) is
restored, even if the user has changed the Points value while the Source
Mode was set to Tracking.
• Whenever the number of sweep points change:
— All trace data is erased
— Any traces with Update Off will also go to Display Off (like going
from View to Blank in the older analyzers)
— Sweep time is re-quantized
— Any limit lines that are on will be updated
— If averaging/hold is on, averaging/hold starts over
1001
Saved in instrument state
Normally the minimum is 1, but in Tracking Source Mode, the minimum
value of Points is 101. If you go into Tracking Source Mode with fewer points
than 101, it sets Points to 101.
40001, or the maximum number of points supported by the source in Tracking
Source mode, whichever is less
