Spectral output is tested under the following conditions: Modulation scheme is π/4 DQPSK with a bit transfer rate of 384 kB/sec and a root Nyquist filter with = 0.5 per RCR STD-28. The spectrum analyzer settings are as follows: Resolution bandwidth: 10 kHz Video bandwidth: 100 kHz Sweep time: 5 seconds 2. This chart documents the modulated output power delivered for a fixed adjacent channel interference (ACI) rejection of 55 dBc at a 600-kHz offset. -15°C +25°C In Out +70°C |
