Hardware Compatibility Tables
When replacing a receiver (Rx) assembly you
must check the Multiplier-Filter and IF Filter
option numbers (last three digits in the part
number). These numbers must be the same for
the original and the replacement.
LO MON Frequency Calculation
Calculate the LO MON frequency as follows.
1.
First, find the difference between the TX Frequency and the Multiplier
Frequency.
2.
Then subtract 140 MHz from the difference to arrive at the LO MON
frequency.
The LO MON frequency is always between 2060 and
2160 MHz.
7/8 GHz Example:
11 GHz Example:
Multiplier Frequency = 9800.000 MHz
Transmit Frequency = 11192.500 MHz
Transmit Frequency = 7561.500 MHz
Multiplier Frequency = 8900.000 MHz
Difference = 2238.500 MHz
Difference = 2292.500 MHz
