The waveform generator described contains random-access memory with a capacity of 256 bytes with serial writing and reading, a digital-analog converter, and a programmable timer. Data on the signal shape are stored in RAM in the form of 8-bit words, which allows a signal to be represented with an amplitude and duration resolution of 256 × 256. The readout frequency is set by program within 1-2-32 MHz, which corresponds to a range of signal periods at the generator output of 256-1012 μsec. After programming and triggering, the generator operates independently of the computer.
