Concept of Segment Sweep
To perform a segment sweep, you must define two or more frequency
ranges, called segments, and then specify the number of points, IF
bandwidth, power level, sweep mode, sweep delay time, and sweep time
for each segment. All segments are swept sequentially as if swept in one
sweep operation.
• By skipping the frequency range, which does not need to be
measured, you can sweep and measure only the portions you
need.
• You can define the optimum measurement conditions for each
of the segments you designate. For example, you can specify as
many points as possible in a segment requiring high trace
resolution and as few points as possible in a segment not
requiring high resolution. This shortens the measurement time,
enabling you to optimize the overall measurement throughput
by not having to perform the entire operation under the same
measurement conditions of a particular frequency range.
To evaluate a band pass filter having the transmission characteristics
shown in the following figure. for example, you can select the frequency
ranges you need from A through G and determine the measurement
conditions shown in the table below This enables you to measure them
simultaneously in one sweep operation.
