Return Loss Measurement

Return Loss Measurement

Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Sixth Edition

Calibrating the Return Loss Module

Whenever a Return Loss module is in the mainframe, a return loss value is 
displayed. The calibration values used are either the most recently 
measured, where these are available, or factory default values.

If you are unsure of any of the calibration values that you are using, or if 
you have changed the measurement setup, take the appropriate 
calibration measurements again.

• First, calibrate the return loss module against a component of known 

reflectance. 

• The Agilent 81000BR Reference Reflector allows you to make a Reflectance 

Calibration and a Termination Calibration. 

• These procedures are decribed in “

Calibration using the Agilent 81000BR 

Reference Reflector

” on page 177.

• The Agilent 81610CC Reference Cable also allows you to make a Reflect-

ance Calibration. Use 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 195), you must also measure 

the insertion loss of the Reference Cable and mesurement patchcord. 

• These procedures are decribed in “

Calibration using the Agilent 81610CC 

Reference Cable
