(stimulus-response mode) is underlined. Auto-coupled sweep times are
usually much faster for swept-response measurements than they are for
spectrum analyzer measurements.
NOTE
In the stimulus-response mode, the II (reactance versus resistance) of the OUT can determine the
fastest rate at which the spectrum analyzer can be swept. To determine whether the analyzer is
sweeping too fast, slow the sweep time and note whether there is a frequency or amplitude shift of
the trace. Continue to slow the sweep time until there is no longer a frequency or amplitude shift.
