Agilent 81610A/11A/12A/13A/14A Return Loss Module, Fifth Edition 75
Figure 44 81610CC Reference Cable - Adjusting Input Power to 0.0 dB Return Loss
12 Set the ‘Attenuation’ such that the Power Sensor shows a power [P]
reading of exactly -20.0000 dB
13 At the Return Loss module,
a Press [Menu], scroll to <Show calibration>, and press [Ok]
b On the ‘Calibration parameters’ page labelled ‘Return Loss
Diode’, note the values of [Ref] and [Meas].
14 Calculate the Return Loss, RL, for this wavelengh
RL @ _________nm = Ref - Meas
15 Repeat steps 1 to 14 for the upper wavelength, that is 1550 nm
NOTE If the return loss of the 81610CC Reference Cable differs from the
value printed on the cable, use the newly measured return loss value
as the Reference Reflectance for the wavelength at which it was
measured.
