B-7
Engineered to Endure
• Tx Rated Power
Displays transmitter output power at 1 dB compression. Tx rated power
information is contained within the part number. More information about locating
the power level of the IBUC is found in Appendix A .
• Frequency Band
Displays the standard name of the band.
• RF Frequency Range
Displays the valid RF frequencies for the IBUC. The RF Frequency range for each
of the various IBUC bands is listed in Table 2.1 on page 2-3 through Table 2.5 on
page 2-7 .
• IF Frequency Range
Displays the valid IF frequencies for the IBUC. The L-band IF Frequency range
for each of the various IBUC bands is listed in Table 2.1 on page 2-3 through
Table 2.5 on page 2-7 .
• LO Frequency
Displays the valid LO frequencies for the IBUC. The LO Frequency for each of the
various IBUC bands is listed in Table 2.1 on page 2-3 through Table 2.5 on
page 2-7 .
• Spectral Inversion
Options include:
•
Non-Inverted
•
Inverted
When inverted, the relationship between the RF and IF frequencies is inverse;
that is, if the modem frequency lowers, the RF frequency increases and vice-
versa.
• Total System Hours
Displays the total number of hours that the system has been operating, that is, the
total number of hours that the system has been powered on. This accumulates after
cycles (imagine it like a odometer of a car).
• Total Tx Enabled Hours
Displays the total number of hours that the transmitter has been enabled (that is,
with transmit = On and mute = Off).
• Internal 10 MHz
Indicates whether the IBUC has the internal 10 MHz optional installed or not.
• Supply Voltage
Displays the power supply voltage range for which the IBUC was designed. The
Supply Voltage Range is based on the configuration of your IBUC.
