Measurements Using the Swept List Mode

When using a list frequency sweep, the HP 8753E has the ability to sweep arbitrary frequency
segments, each containing a list of frequency points. Two different list frequency sweep modes
can be selected:
Stepped List Mode
Swept List Mode
The ability to completely customize the frequency sweep while using swept list mode is
useful when setting up a measurement for a device with high dynamic range, like a iilter. The
following measurement of a filter illustrates the advantages of using the swept list mode.
For in-depth information on swept list mode, refer to "Swept List Frequency Sweep" in

Chapter 6, "Application and Operation Concepts. n
"lb Use Swept List Mode" in Chapter 5, "Optimking Measurement Results."

Connect the Device Under Test

1. Connect the equipment as shown in the following illustration:
2. Set the following measurement parameters:
In this mode, the source steps to each defined frequency point,
stopping while data is taken. This mode eliminates IF delay and
allows frequency segments to overlap. However, the sweep
time is substantially slower than for a continuous sweep with
the same number of points.
This mode takes data while sweeping through the defined
frequency segments, 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 deiined. The frequency segments in this mode
cannot overlap.
