Step 13. Using the front panel knob, locate the maximum value of the data trace
for the 50 MHz to 2.0 GHz frequency range.
Step 14. Write the maximum value in the “Return Loss Test Record”, Table 6-3
on page 6-14, for the port being measured.
Step 15. Repeat the previous two steps for the other frequency ranges listed in
the “Return Loss Test Record”.
Step 16. Press:
[SEQ] > TTL I/O > PARALLEL OUT ALL > [34] > [x1]
Step 17. Using the front panel knob, locate the maximum value of the data trace
for the 50 MHz to 2.0 GHz frequency range.
Step 18. Write the maximum value in the “Return Loss Test Record”, Table 6-3
on page 6-14, for the port being measured.
Step 19. Repeat steps 10 through 18 for the remaining test ports (2 through 16).
Step 20. After all Transmission ports have been measured, move the
high-quality load attached on the Transmission port to the Reflection
port on the test set. Repeat steps 10 through step 19, but select the
Reflection ports instead of the Transmission ports.
This completes the performance testing instructions.
