Accuracy Formats other than FSK, 8/16VSB, 16/32
APSK, and OQPSK. Conditions: Full scale
signal, fully contained in the measurement
span, frequency < 3.6 GHz, random data
sequence, range
≥ –30 dBm, start frequency ≥
15
% of span, alpha/BT ≥ 0.3 (0.3 to 0.7 for
OQPSK), and symbol rate
≥ 1 kHz. For
symbol rates < 1 kHz, accuracy may be
limited by phase noise. Averaging = 10
