The TR8818A digitizer, and 6103 amplifier module are all fully programmable for automated testing,

remote operation, and quick setups. Remote commands set the digitizers' sample clock rate, pre-trigger

memory fraction, waveform record size, and input offset. Remote commands can also arm and trigger

the digitizers. A Look-At-Me flag gets set when data is ready for readout. Look-At-Me (LAM) gets

translated to a GPIB Service Request (SRQ) by the LeCroy 8901A.
