RF Cable Sweeps Procedure
This section provides step-by-step procedures for calibrating the test equipment and performing
insertion loss measurements of the RF cable. Refer to Figure K15.
Step 1. Calibrate the test equipment.
Step 2. Replace the barrel connector with the cable to be measured. Use the appropriate
adaptors depending on the type of connectors at the ends of the cable. Figure K15
shows an example).
Step 3. Enable the RF on the signal generator.
Step 4. From the Delta marker found in Step 1 take the loss reading in db. Record the results.
Step 5. Perform steps 2 through 4 for all cables.
