8. Measure all other non-ratio parameters shown in Table 3-1 by se
-
lecting the S-parameters S12, S33 or S44 and setting up the user de
-
fined ratios as described in Steps 2 through 6. Also, install a short
on Ports 3 and 4 as indicated in Table 3-1.
NOTE
Viewing Port 3 and Port 4 with a short attached will cause a
significant ripple on the RF display. This is normal.
The non-ratio parameters test results reveal where the fault may be lo
-
cated.
For example, if the non-ratio parameters test results for a MS462XB
shows that b2/1 has a glitch appearing on the frequency response trace,
but a1/1 and b1/1 are okay, then the fault is possibly in the Port 2 module
or the cable connected between the Port 2 module and the Down Conver
-
sion Module.
