Figure 7-4 One Port Insertion Loss Measurement

Step 2. Set the analyzer to the One Port Insertion Loss measurement:

Press

Mode, Stimulus/Response, One Port Insertion Loss

Step 3.

Preset the analyzer:

Press

Mode Preset, Meas, One Port Insertion Loss.

Step 4. Set the start and stop frequencies:

Press

FREQ Channel, Start Freq, 100, MHz.

Press

FREQ Channel, Stop Freq, 2, GHz.

Step 5. Turn averaging off:

Press

Meas Setup, Avg Mode, Off.

Step 6. Calibrate the measurement:

Press

FREQ Channel, Calibrate and follow the instructions on the Calibration

Wizard. The analyzer will calibrate over the desired frequency range.

Step 7.

Connect the DUT to the analyzer, as described in step 1. Note that the

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

measurement.

Step 8. Change the amplitude scale to 2 dB per division:

PRess

AMPTD Y Scale, Scale/Div, 2, dB.

Step 9. Place a marker on the results at the frequency of interest. In this

example, the marker is placed at 986.667 MHz. As you can see the loss

is 2.1 dB.
