Frame Error Rate performance:

• FER = 1E-2 @ Eb/No = 1.4 dB (2032-bit frame, rate 1/3)
• FER = 1E-3 @ Eb/No = 1.6 dB (2032-bit frame, rate 1/3)
• FER = 1E-2 @ Eb/No = 3.1 dB (768-bit frame, rate 3/4)
• FER = 1E-3 @ Eb/No = 3.5 dB (768-bit frame, rate 3/4)

Ancillary test features: PRBS11 test sequence, BER tester, Frame Error Rate counter

Single 5V supply. Connectorized 3”x 3” module for ease of prototyping. High-speed 98-pin connectors (left, right). Interfaces with 3.3V logic
