Front-Panel Key Reference
Sweep
NOTE Turn markers off (Marker, Off) when entering or exiting segmented
sweep (Segmented, (On)(Off)).
Performing a factory preset will turn segmented sweep off. This is also
true if you select full span or last span.
Functions which are parameters of segmented sweep are not available
when accessed by pressing the following front-panel keys:
Auto Couple,
BW/Avg (Resolution BW and Video BW), Frequency (the entire softkey
menu),
Span (see above), and Sweep (Sweep Time and Points).
When the sweep trigger is set to any of the trigger selections other than
free run, no sweep occurs until the trigger condition is met. Once the
trigger occurs, all segments are swept, completing the entire trace.
NOTE For spectrum analyzers with Option 1DN or Option 1DQ, the tracking
generator must be turned on (
Source, Amplitude (On)) before you set up
the segmented sweep table.
The on/off state of the segmented sweep mode and the segmented sweep
table can be saved as a “state” type file (see page 6-74) or as part of the
power on/preset function (see page 6-92).
NOTE When loading a “state” type file, segmented sweep will not turn on if
any of the parameters in the file contain optional instrument settings
not currently loaded on the analyzer or frequency settings outside the
current range of the analyzer.
Edit Accesses the segmented sweep editor, where a
maximum of thirty-two segments can be defined by the
segment number and the six parameters described
below. Use the data control keys described on page 2-5
to enter the setting as each parameter is highlighted.
Refer to the “Editor” section above for more
information.
