Swept List Frequency Sweep (Hz) - HP 8753E User Manual

Swept List Frequency Sweep (Hz)

frequency sweep modes. The swept list mode allows the analyzer to sweep a list of arbitrary
frequency points which are defined and modified in a way similar to the stepped list mode.
However, this mode takes data while swe&ng through the defined frequency points, increasing
throughput by up to 6 times over a stepped sweep. In addition, this mode allows the test port
power and IF bandwidth to be set independently for each segment that is delined. The only
restriction is that you cannot specify overlapping frequency segments.

The function of this menu is the same as in the stepped list mode.

Using the ~~~~~ or f$E& softkey within the edit list menu will display the edit subsweep menu.
This menu lets you select measurement frequencies arbitrarily. Using this menu it is possible to
define the exact frequencies to be measured on a point-by-point basis at specific power levels
and IF bandwidth settings. The total sweep is defined with a list of subsweeps.
The frequency subsweeps, or segments, can be delined in any of the following terms:
start/stop/number of points/power/IFBW
n
n
center/span/number of points/power/IFBW
n
n
See "Setting Segment Power" and "Setting Segment IF Bandwidth" for information on how
to set the segment power and IF bandwidth.
The subsweeps may be entered in any particular order but they cannot overlap. The analyzer
sorts the segments automatically and lists them on the display in order of increasing start
frequency, even if they are entered in center/span format. The data is shown on the display as
a single trace that is a composite of all data taken. The trace may appear uneven because of
the distribution of the data points, but the frequency scale is linear across the total range.
Once the list frequencies have been dellned or modified, the list frequency sweep mode can be
