MN-DMD2050E Revision 2
Sets the minimum carrier receive level when a carrier drops
below this level. The modem will sweep and try to acquire a
new signal. This prevents extremely small carriers from falsely
locking the modem.
Select an EB/NO level that will trigger an alarm when the
received EB/NO is worse.
Set the Data Rate in bps steps via the
Front Panel Arrows or Keypad.
