the loss for each channel by using the multiplexer control box to switch
between each channel (pass).† For
example, to measure channel 1 (pass 1), select the binary equivalent to 1
on the multiplexer control box.

each reading in the calibration data sheet.† Must be <= 2dBm for passing.† NOTE:† Donít forget
to include both test cable loses in recording.
recording measurements for Step 2, calculate the difference of insertion
loss between all 4 ports (X+, X-, Y+, Y-) for each pass (1-5).† Must be <=0.5dBm for passing.
