3.5 Sweep Setup
The sweep is the process for continuous data point measurement with stimulus values with a
specified sequence.
3.5.1 Sweep type
The network analyzer supports the following six sweep types:
1) Linear frequency
This is the default sweep type of the instrument, and the frequency linearity continuously
covers the whole frequency range.
2) Logarithmic frequency
The source frequency will increase with logarithmic step under the logarithmic frequency
setting, and the frequency ratio of two adjacent frequency points is the same.
3) Power sweep
The power sweep will be carried out at fixed frequency, with the max. settable sweep range
of 50 dB and the default power sweep range of -30 dbm ~ +20 dBm.
4) Fixed frequency
The fixed frequency sweep mode will set the analyzer to the single sweep frequency, which
will accurately and continuously sample the measurement data according to the time interval
determined by the sweep time and number of measurement points as well as display
changes of the measurement data over time.
5) Segment sweep
The segment sweep setting starts the sweep consisting of multiple segments, and each
segment can independently define the power level, IF bandwidth, and sweep time. When
calibration on all segments is completed, the calibrated measurement can be carried out on
one or more segments. The segment will be defined in the increasing frequency order, and
the frequency ranges can’t be overlapped. The power level of all segments shall have the
same attenuator setting, so as to avoid damaging the attenuator due to frequent switching.
When the currently defined segment and the defined segment have different attenuator
settings, the analyzer will automatically change the power level and attenuator settings of the
defined segments.
6) Phase sweep
Sweep the phase of one or more sources relative to another source, with the measurement
value of -360° ~ +360°.
3.5.2 Sweep time
After the measurement setting is completed, the analyzer will satisfy some specific measurement
demands with the shortest sweep time as much as possible, but the sweep time can be increased. If the
