Notes: 
1.  With respect to the input port on 2:1 Transmit Processor. 
2.  A CW carrier of this amplitude applied to the RF input will exercise the full-scale range of the A/D converter.  Full scale is 

analogous to 100% OMI for Analog Lasers. 

3.  Variable Attenuator on 2:1 Transmit Processor set to 0 dB. 
4.  Variable Gain Control on 2:1 Receive Processor set to 0 dB. 
5.  Add Link Gain (dB) to Transmit Processor RF input level to determine Receive Processor RF output level.

NPR Notes: 
1.  Input power is specified with respect to the input port of the Transmit Processor module. 
2.  Variable Attenuator on 2:1 Transmit Processor set to 0 dB and Variable Gain Control on 2:1 Receive Processor set to 0 dB. 

Note: 
Unless otherwise stated, all link performance specifications shown reflect minimum performance over the specified operating temperature 
range.
