The Tektronix 2642A is an FFT analyzer with a DC to 200 kHz frequency range. It performs signal acquisition and processing, and uses a PC running MS-DOS connected via a serial port for mass storage and graphics.
It has two or four inputs with dedicated 12-bit (optionally 16-bit) ADCs, and an optional arbitrary function generator. Another option is a "zoom" feature that provides a span as small as 10 Hz about the frequency of interest.
