The load matc

indicator of cable problems. Y
ou can further v
erify
a
faulty cable b
y measuring the reection of the cable. P
erform an S11 1-p ort calibration
directly at port 1 (no cables). Then connect the susp ect cable to port
1 and terminate the
open end in 50 ohms.
Figure 9-1 shows the return loss trace of a go o d (left side) and faulty cable. Note that the
imp ortant characteristic of a cable trace is its level (the go od cable trace is muchlower) not
its regularity. Refer to the cable manual for return loss sp ecications.
