Manual sweep
For swept spectrum measurements, sweep times can be very long for low
resolution bandwidth to span ratios. You can use manual sweep to disable the
analyzer’s automatic sweep. Manual sweep lets you tune the analyzer to a discrete
frequency. This lets you measure the amplitude of discrete frequencies without
waiting for the analyzer to sweep through an entire span—a considerable
advantage when using a narrow resolution bandwidth.
Manual sweep is also useful when making automated measurements. Using manual
sweep dramatically reduces measurement time since it’s much faster to transfer
amplitude data for a single frequency over the GPIB rather than sending data for
the entire display.
