The number of frequencies required for determining a PASS can
be set from 0 to 12. If the setting is on 0, then no indication of
PASS/REFER will be made. This setting is used in conjunction
with the PASS SNR (Display 30, page 44) to set the criteria for
the overall test PASS/REFER indication. For example, if the PASS
SNR is set to 5 dB and the number of frequencies for PASS is set
to 3, then the test must contain at least 3 frequencies where
the emission is at least 5 dB above the noise to indicate a PASS.
The number of frequencies for PASS should also be based on
the number of frequencies being tested. Setting the number of
frequencies for PASS to 5 when only 4 frequencies are being
tested would result in every test being labeled as a REFER.
NOTE: To disable the PASS/REFER indication set the number of
frequencies for pass to 0.
NOTE: Diagnostic protocols Display the SNR graph with purple
bars. Once the "Number of Frequencies for PASS" is set above
zero, green bars Display to identify this setting.
Press the CHANGE keys to select an option and the NEXT
key to exit (Display 31).
Selecting the RESET arrow key in the Reset Protocol menu
(Display 32) will return the selected protocol settings to their
original factory settings. Press the NEXT key to exit.
NOTE: This does not affect the instrument settings or the
settings of any other protocol.
Once all of the settings have been selected for the protocol,
these settings can be saved by selecting the SAVE keys
(Display 33). Press the DONE key to exit.
Selection of the DONE before saving will not save the
selection made to the protocol.
