Description<br />

In stimulus-response mode, auto-coupled sweep times are usually much faster for<br />

swept-response measurements. Stimulus-response auto-coupled sweep times are typically valid<br />

in stimulus-response measurements when the system’s frequency span is less than 20 times the<br />

b<strong>and</strong>width of the device under test.<br />

When used as a predefined variable, SWPCPL returns either a “0” or a “1,” depending on the<br />

setting of the SWPCPL parameters. Refer to the following table.<br />
