4.2.2 Converter Menu Options and Parameters

FREQUENCY (GHz):

{17.30 – 18.40 GHz}

Sets the RF output frequency.

CHNL GAIN (dB):

{-20.0 to +30.0, dependent upon input attenuation}

Sets the Channel Gain in 0.1 dB steps.

CARRIER CNTRL:

{ON, OFF}

Allows the user to turn the carrier on/off.

INPUT ATTEN:

{0 - 30}

Sets the input attenuation in 1 dB steps.

CURRENT CHNNL:

{01 – 30}
Selects the current channel of the unit. Each channel
allows entering of an independent set of parameters
(Frequency, Gain, etc.). For example, Channel 1
Frequency might be set to 5.9 GHz and Channel 2 could
be set to 6.0 GHz. Any of the other parameters could be
different as well. The advantage is that by changing the
channel number, a completely different setup can be
achieved.

4.2.3 Switch Menu Options and Parameters

This Menu is only available when the upconverter is connected in a 1:1 or 1:N Switch
configuration as the Backup Unit.

BACKUP MODE:

{MANUAL, AUTO-NONREVE, AUTO-REVERTI}

Sets the Backup Mode of the switch.

Manual: A Prime Converter can be backed up through
manual control only.

Auto-Nonrevertive: A Prime Converter will be backed
up if it fails. It will remain backed up until it is manually
unbacked.

Auto-Revertive: A Prime Converter will be backed up if
it fails. If a second Converter, which has been deemed
higher priority (see Monitor Backup State below) fails,
the switch will unback the first and backup the second
Converter. If the first Converter recovers after it has
been backed up (i.e., no longer has a fault), and a
second Converter fails, the recovered unit will be put
back on line and the new faulted unit will be backed up.
