Monitor Functions
Introduction
Programmable Min/Max current alarms.
Selectable size of 64 to 262,144 bits, in 16-bit steps (With added limitations for G.704 frame
boundaries).
Size selection is displayed in bytes and milliseconds.
Supports asymmetric operation - when buffer is clocked from Tx clock, Rx and Tx rates do not
need to be identical.
Eb/No estimate:
2 to 10 dB with ±0.3 dB accuracy
0 to 16 dB with ±0.5 dB accuracy
Corrected Bit Error Rate, 1E-3 to 1E-10
Frequency offset, ±32 kHz range, (or 200 kHz range, depending on band and symbol rate) 100 Hz
resolution
Buffer fill state, in percent
Receive signal level: 950-2250 MHz band accuracy: ±3 dB
50-180 MHz band accuracy: ±2 dB
