Modem Tuning
If the MUX is equipped with modems on any of the ports, set
the modem levels while in the monitor mode. Press F7 to access
the Modem Tuning Window (Fig. 7). Use the + (plus) and - (mi-
nus) keys to select the port (selected port is displayed in the first
field of the window). With a level meter on the port to be ad-
justed, use the keys listed in the window to control the transmit
and raise or lower the level, as needed. The receive portion of
the modem has an AGC input, so requires no adjustment.
NOTE: Do not tune above -4dbm or below -34dBm as the
waveforms become distorted at those levels.
Reports
Use this menu item to run configuration reports to the screen,
printer or file. Such reports are useful in creating records and
reference files. Such files allow future reference to see how a
particular unit is configured. Several configurations can be re-
ported. A query box will ask for starting and ending configura-
tion names (press Tab to see a default box listing of existing
configurations), report destination and file name (if outputting
to file).
