pi/4 DQPSK or QPSK Formats: ±0.15 dB (with raised cosine or root-raised cosine filter and alpha >=0.35; with 10

kHz <symbol rate <1 MHz; at RF Freq. >25 MHz; power <max. specified -3 dBm)

Constant Amplitude Formats (FSK, GSMK, etc.): no degradation in power level accuracy

Level Accuracy with ALC Off

: ±0.5 dB, typical (after power search is executed; relative to CW level accuracy with

ALC on; with burst off if external I/Q is enabled: [square root of (I

)

Typical, level accuracy with

ALC on will be maintained with drive levels between 0.25 and 1.0 V

rms

When applying external I/Q signals with ALC

off, output level will vary directly with I/Q input level.
