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 ModeIn 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.

Swept List ModeThis 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.

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.
