Refer to “Trace Menu” on page 3-65 for additional information.
(Trace + Memory) / 2
(not shown)
In the (Trace + Memory) / 2 graph the yellow trace
is the result of adding the purple trace to the
active trace and then dividing the result by 2.
This math function is most useful when measuring
one-port Cable Loss (using the Cable Loss
measurement).
1. Connect a Short to the end of the cable and
store the trace into memory.
2. Next, connect an Open to the end of the cable
and apply (Trc + Mem) / 2 math function.
Because the ripple generated by the Short and
Open are 180° out of phase, the effect of this
math function will be to cancel out the ripple
resulting in a more accurate cable loss
measurement.
