SNA5000A Vector Network Analyzer User Manual 32
Log frequency sweep:
Set the measured abscissa frequency scale to log scale, To observe
a wider frequency range, the calibration interval in the full frequency
band is not uniform and presents periodic changes.
Power Sweep:
The power sweep will increase or decrease the power of the source according
to the walk length. Power sweeping is used to characterize power-sensitive
circuits through measurements such as gain compression. In the Scan Type
dialog box, you can specify "Start Power", "Stop Power", "CW Frequency",
"Points".
Section sweeping:
"Segmentation Sweep" activates a sweep consisting of frequency sub
scans (called segmentation). For each segment, you can define a
separate power level, IF bandwidth, IF bandwidth for each port, sweep
time, delay, sweep mode. After the measurement calibration has been
performed on the entire scan or all segments, the measurement values
of one or more segments can be calibrated.
In the segmented scan type, the vector network analyzer performs the following operations.
•
Sort all defined segments in order of increasing frequency.
•
Measurements were made at each point.
•
Display a trace containing all retrieved data.
Limitations on segmented sweeping:
•
The frequency range of one segment may not overlap with the frequency range of any
other segment.
•
The number of segments is limited only by the combined data points of all segments in
the sweep.
•
The frequency range of one segment may not overlap with the frequency range of any
other segment.
•
The number of segments is limited only by the combined data points of all segments in
the scan.
