Measuring Return Loss Using the Reflection Calibration Routine
This procedure uses the reflection calibration routine in the proceeding procedure “Making a Reflection Calibration Measurement" on page 51 to calculate the return loss of the 370 MHz low pass filter.
1After calibrating the system with the above procedure, reconnect the filter in place of the short circuit without changing any analyzer settings.
2Use the marker to read return loss. Position the marker with the front- panel knob to read the return loss at that frequency.
Rotate the knob to find the highest peak and the readout is the maximum return loss.
