DMD2050E Universal Satellite Modem User Interfaces
MN-DMD2050E Revision 2 4–16
{-30 to –90} 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.
{0.0 – 9.9 dB} Select an EB/NO level that will trigger an alarm when the
received EB/NO is worse.

{ENABLED, DISABLE} Enable or disable the Differential Decoder.
Having the decoder enabled ensures
proper phase lock. May not be adjustable
in some modes.
