Making Measurements
Measuring S21 Forward Transmission using an Enhanced Response Calibration
Enter the Measurement Parameters
Press ( or ) on the analyzer
to set the analyzer to the default mode which includes measuring S
21
on
measurement channel 1.
NOTE This example measurement uses the default instrument parameters for
an S
21
measurement. If your particular measurement requires different
parameters (such as frequency range, source power level, number of data
points, and sweeptime), enter them now.
Perform an Enhanced Response Calibration
An enhanced response calibration uses known standards to correct for
source match and frequency response errors when using narrowband
detection. When you perform an enhanced transmission response
calibration, the analyzer performs correction at each data point across
the selected frequency band. The default number of data points per
sweep is 201, but you can select any number between 3 and 1601.
Interpolation recalculates the error correction array for reduced
frequency spans. If the frequency span is increased, the calibration is
invalidated, and the default response calibration is automatically
restored.
