Claim of US Patent No. 9,287,833

1. A system, comprising:
a predistortion module comprising at least one predistortion function, the predistortion module configured to:
receive a baseband signal; and
process the baseband signal;
a power amplifier configured to receive one processed baseband signal;
a model calculator configured to:
program priorities for each of the at least one predistortion functions, and
send a trigger signal; and
a trigger module configured to:
in response to receipt of the trigger signal, initiate data capture from the power amplifier, and
send an advanced trigger signal to a capture buffer, wherein the capture buffer captures data from the power amplifier;
wherein the trigger module is configured to continue a search of data to capture until it receives the trigger signal with
a false value, preferably the trigger module is configured to discard data in the process of being captured when the false
value for the trigger signal is received, more preferably the trigger module is further configured to retain data captured
before the false value for the trigger signal is received.
