The
Sweep
key activates the Sweep Time function, and accesses the
sweep menu keys:
Sweep Time Auto Man
,
Sweep Cont Single
, and
Swp Coupling SR SA
.
Sweep Time Auto
Man
selects the length of time in which the spectrum analyzer sweeps the
displayed frequency span. In all spans, the sweep time varies from
5 milliseconds to 2000 seconds. 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. Key Access:
Sweep
Sweep Cont Single
switches the spectrum analyzer between the continuous-sweep mode
and the single-sweep mode. If the spectrum analyzer is in single-sweep
mode, Single is underlined. Press
Single
on the front panel, to enable a
sweep when in single-sweep mode. When continuous-sweep mode is in
use, one sweep follows another as soon as it is triggered. Pressing
Preset
, or turning the power on, selects continuous sweep.
Key Access:
Sweep
Swp Coupling SR
SA
selects stimulus-response (SR) or spectrum-analyzer (SA) auto-coupled
sweep times. 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.
