NOTE Although the performance for all four S-parameters on ES models are
measured, only the uncertainties associated with the items indicated in
2-4 will be used for the system verification. The other characteristics are less
important for verifying system performance and they will not appear on the
printout. If a measurement fails, note which device and S-parameter failed,
and continue on with the remaining tests.

5. Enter Test 28 (using step keys, entry keys, or front panel knob). Repeat steps 1 through
4 in this section with the 40 dB attenuator (Ver Dev 2).
6. Enter Test 29 (using step keys, entry keys, or front panel knob). Repeat steps 1 through
4 in this section with the 50Ω airline (Ver Dev 3). For an example of how to perform
proper airline connections, refer to
