Sweep Type-Single Hold vs. Continuous
Continuous sweep continually sweeps the selected fre-
quency band updating the measured value with each
sweep. An asterisk (*) is blinking on the left side of the
display to indicate sweep rate. The single hold mode
will freeze a trace on the display and hold is displayed
on the right. Holding a trace is also helpful before sav-
ing the trace, (more about saving traces under that
heading later in this section).

cies. The second is to enter a span frequency, which is
the desired width of the band, and a center frequency,
that will be used as the center of the band.
