M/A-COM Inc.
Modulation scheme is π/4 DQPSK with a bit transfer rate
of 384 kB/sec and a root Nyquist filter with
RCR STD-28. The spectrum analyzer settings are as follows:
Resolution bandwidth: 10 kHz
Video bandwidth: 100 kHz
Sweep time: 5 seconds
for a fixed adjacent channel interference (ACI) rejection of 55
dBc at a 600-kHz offset.
