displays the output of the sweep-time DAC (SWP-DAC) from the sweep-ramp generator that is on the A7 Analog Interface assembly. This is a service diagnostic function and is for service use only.

selects stimulus-response (SR) or spectrum-analyzer (SA) auto-coupled sweep time. In stimulus-response mode, auto-coupled sweep times are usually much faster for swept-response measurements. Stimulus-response auto-coupled sweep times are typically valid in stimulus-response measurements when the system’s frequency span is less than 20 times the bandwidth of the device under test.

selects the length of time in which the analyzer sweeps the displayed frequency span. In all non-zero frequency spans, the sweep time varies from 20 milliseconds to 100 seconds. In zero frequency span, the fastest sweep time is 15 milliseconds. Reducing the sweep time increases the rate of sweeps. The sweep time can be changed using the step keys, the knob, or the numeric keypad.
Provides sweep times from 20 ,US to 20 ms in zero span.
