A combined pulse generator and digitizer based on a RISC processor has been designed and tested by59Co NMR. The pulse generator provides a 16‐bit TTL‐level output with 100 ns resolution and is programmable in the high‐level language FORTH. The digitizer supports two channels, each with a 10 bit, 40 MSPS analog‐digital converter and online averaging in a 24×1024 bit memory, which is directly accessible by the RISC processor.
