Number of Points
parameter item, Enter the number of points required, Press
ENTER
to exit editing mode.
The number of data points collected by the vector network analyzer during the
measurement sweep can be set to any number between 1 and 100001.
Note: Maximum point limits may differ for some measurement classes.
•
For maximum trace resolution, use the maximum data points.
•
For faster throughput, use a minimum number of data points to provide an acceptable
resolution.
•
To get the best number of points, look for values that do not differ significantly in the
measurement as you add points.
•
To ensure accurate measurement calibration, ensure that the user uses the same number
of points for calibration and measurement.
•
Points are the number of data items collected in one sweep. This number can be set
separately for each channel.
•
To obtain high trace resolution for excitation values, select a larger point value.
•
For high throughput, keep the smaller point value within the allowable trace resolution
range.
•
For high measurement accuracy after calibration, use the same number of points as the
actual measurement.
