SWEEP
The spectrum analyzer frequency sweep (sweep times 220 msec), once triggered, continues at a uniform rate
from the start frequency to the stop frequency unless new data entries are made to the analyzer from the front
panel or the HP-IB. With faster sweeps, changes to center frequency, for example, appear continuous. With long
sweep times, a change in center frequency noticeably suspends the sweep while the analyzer updates its state and
readout, then the sweep continues from where it was, tracing out the new spectrum.
