10421 Cannot lock to carrier.
This error only occurs when attempting to demodulate OFFSET QPSK
signals. It indicates that the demodulation algorithm is unable to lock to
your signal. Possible causes may be:
1. There is no carrier signal.
2. Carrier signal is present, but Demod settings do n ot ma tch th e
modulation format of the OFFSET QPSK signal being measur ed .
3. OFFSET QPSK signal is too noisy to achieve carrier lock.
10425 B7D DSP Code Install Fail Opt.231. Contact your Service
Center.
The Digital Signal Processor algorithm files required to
