Getting Started with Return Loss Making a Return Loss Measurement
26 Agilent 81610A/11A/12A/13A/14A Return Loss Module, Fifth Edition
Calibration using the Agilent 81610CC
Reference Cable
Use the Agilent 816100CC Refernce Cable to make a Reflectance
Calibration, and the measurement patchcord to make a Termination
Calibration.
To measure insertion loss and the front panel delta of the system (see
“Calculating the Front Panel Delta” on page 41), you must also
measure the insertion loss of the Reference Cable and measurement
patchcord.
Reflectance Calibration
Use this procedure to calibrate the Return Loss module against a
component of known return loss.
1 Attach the source to the Return Loss module’s input as shown in
Figure 16. Attach the high return loss connector of the reference
cable to the output.
Figure 16 Measuring the Return Loss of the Reference Cable - External source
or Figure 17 if you are using an internal source
(Agilent 81611A/2A/3A/4A Return Loss modules only).
Figure 17 Measuring the Return Loss of the Reference Cable - Internal Source
Attach the high return loss connector of the reference cable to the
output.
TIP For best results and higher repeatability, fix the cable.
2 Move to [FPDelta], press [Edit], set the value to 0.000, then press
[OK].
