Overview of Sweep Types
The network analyzer supports six sweep types shown below.
1) Linear frequency
This is the default sweep type of the instrument. The whole frequency range is covered continuously by the frequency linearity.
2) Logarithm frequency
In the logarithmic frequency mode, the source frequency increases in logarithmic steps, and the frequency ratio of every two
adjacent frequency points is identical.
3) Power Sweep
The power is scanned at the point frequency. The maximum sweep range is 50dB. The default frequency sweep range is -30dBm
to +20dBm.
4) CW Time
In the point frequency sweep mode, a single sweep frequency is set in the analyzer, measurement data are accurately and
continuously samples at the intervals determined according to the sweep time and the number of measurement points, and
changes of measurement data with time are displayed.
5) Segment Sweep
Segment sweep aims to start sweep of several segments. The power level, IF bandwidth and sweep time of each segment can be
set independently. After calibration of all segments, one or several segment(s) can be measured according to the calibrations.
Segments are defined according to the frequency increase sequence, and the frequency range must be prevented from
overlapping. The attenuator settings of the power levels of all segments must be identical to prevent damage caused by frequent
switching of the attenuator. If the attenuator settings of the current segment and defined segment are different, the analyzer will
automatically change the power level and attenuator settings of the defined segment.
6) Phase
Scan the phase of one or several source(s) relative to another source. The measured value is -360° to +360°.
