Using Trace Math to Measure the Efficiency of the DUT

By adding the insertion loss to the return loss of a DUT you can determine the
efficiency of the DUT.
1 Set up your DUT for "Measuring Insertion Loss and Return Loss
Simultaneously" on page 3-26.
2 From the front panel, press Traces > Trace Math > Default Math Trace C >
Log Math C = A + B to add the insertion loss and return loss traces and display
the results in Trace C.
3 If the DUT is 100% efficient, then Trace C will be at 0 dB. Any variation from
0 dB will show you the losses of the DUT.
