frequency range.

Step 6. Connect the test cable (if used) and calibration devices to the analyzer

RF Output, as shown in Figure 7-6, or in the calibration wizard. (If the

DUT is a two-port device, be sure to terminate the unused port in the

characteristic impedance of the device.)

Note that the units of the reference level are dB, indicating that this is

a relative measurement.

This example uses a 50 MHz low pass filter as the DUT.

Step 7. Use the markers to measure the return loss and SWR at any point.

Press

Marker, Normal. Use the knob to place the marker at a frequency

of interest.
