REFTEK 72A07

Below is some configuration-specific information to help you locate your instrument response.

Crystal Chip Generations

RT72A07 digitizers used the CS5323 A/D chip on a RT331 board until about mid 1993. About that time, new digitizers came with the CS5321 chip on an RT371 board. Both generations of the digitizer used the same fir filters, but had different A/D scale factors that depended on input sample rate. The correct response depends on the manufacturing date of the instrument and, for older instruments, when the boards were upgraded.
