NOTE:
For Analog channels, you will need to instruct the
DS2831
where to look for “Gated” quiet line,
GCR or Multiburst, CCR-7 VITS test signals, field and line location. If these changes are made during
testing, said changes will not be saved for the next test. It is recommended to make initial edits to
the channel plan prior to testing, in order to retain channel specifications.
