Setting the Tx Frequency (L-band)
Changing the L-band frequency will cause a change to the RF frequency. To set the L-
band frequency,
1. Establish a connection with the Cyber Hardened IBUC

2. Verify the data in the Band Inversion via
information.
3. Calculate the IF frequency by using the following formulas:
IF = RF - LO
Non-inverted/Low side
IF = LO - RF
Inverted/High side
Note:
RF and LO frequencies for various bands are provided from

Setting Alarm Thresholds
Although the IBUC will function using the factory-configured settings, by setting high
and low level thresholds for the Tx Input/Output you can access more information
about events such as power fluctuations that might trigger an alarm. Alarms will be
generated when the input and output amplitudes fall outside of the threshold ranges.
For this reason, Terrasat recommends that once the user has reached the proper input
and output settings for their budget, to narrow the threshold ranges for alarms. To
display or set alarm thresholds,
1. Establish a connection with the Cyber Hardened IBUC

2. Set the Tx Input High/Low thresholds via
and
for further description.
The IBUC leaves the factory with a default range of
-
15 dBm to
-
60 dBm.
Example
: After observing the unit, you determine that the IBUC operates
consistently at
-
37 dBm. Although the threshold range is 45 dB, that range is too
wide for everyday use. Instead consider setting the input thresholds at ±3 dB; this
would make the high level threshold
-
34 dBm and the low level threshold
-
40 dBm.
3. Tx Output High/Low thresholds are set via
and
for further description.
