Step 7. The Test Software will turn on the source and make a reference measurement, then

prompt you to add in the cable or device to be tested. Leave the calibration cable and

pads connected to the ANT IN port and insert the cable or device to be measured as

shown in the diagram. Press the k1 (Proceed) key to make the insertion loss

measurement.

Review the Results

When making a discrete measurement, the Test Software will display the insertion loss

as a single numeric value (in units of dB).

When making a swept measurement, the Test Software will display the loss on the

screen (in units of dB) and as a plot of loss versus frequency.

•Pressing the k5 (Scr Dump) key will cause the Test Software to pause automated

operation. Press the Print key to send the plot to BTS Laptop Utility program Test Set

Screen Capture window. After the plot has displayed, press the k2 (Continue) key.

•Pressing the k1 (Proceed) key will display the frequency range settings and average

insertion loss for the test. From this point, you may press the k1 (Repeat) key to test

another cable or device, press the k5 (Return) key once to display the Insertion Loss
