in (CAL) menu when measuring transmission or AM delay. A
measurement calibration that corrects for frequency response errors.
Frequency response errors are signal changes as a function of frequency.
See Chapter 6, “Calibrating for Increased Measurement Accuracy” for more
information.
This calibration removes the same frequency response errors as the response
calibration. In addition, it effectively removes the isolation errors in
transmission measurements. Isolation errors result from leakage between
signal paths (crosstalk).
See Chapter 6, “Calibrating for Increased Measurement Accuracy” for more
information.
