List Sweep
The analyzer has a list sweep function that can sweep frequency
according to a predened sweep segment list. Each sweep segment is
independent. For the network analyzer mode, each segment can have
a dierent number of sweep points, power level, and IF bandwidth
value. For the spectrum analyzer mode, each segment can have a
dierent number of points and RBW.
A segment looks like a normal sweep setting. The list sweep function
can combine up to 31 segments settings into 1 sweep. The analyzer
can have two dierent sweep lists. One list for the network analyzer
and the other list for the spectrum analyzer. When both channels are
set to the same analyzer mode, both channels use the same list. This
example describes the following two applications:
Sweep time reduction for lter testing in the network analyzer
mode (including the setup procedure).
Dynamic range enhancement in the network analyzer mode.
Sweep Time Reduction
The following example creates a list sweep to measure a lter that has
a 836 MHz center frequency and a 50 MHz bandwidth. This example
uses the list sweep to reduce the sweep time by setting coarse sweep
points for the rejection band and the ne sweep points for the
passband.
