Jay- you're on track. Simplistically- it's a low frequency spectrum analyser (FFT type)- coverage zero to 25 kHz and dynamic range of 80 dB(or thereabouts) But it's really a lot more than that as it's a two channel instrument and can do all sorts of other stuff as well. If you really don't want it I imagine you won't have too much of a problem selling it. Sort of thing I would have given my eye teeth for a while back. Now-- all the eye teeth have fallen out!!!

It does FFT and other signal processing functions. Inside is an embedded 21MX but with the front pannel replaced with the custom panel for the 5423A. 64KB semiconductor memory, microcode extensions, and sw loaded from cartridge tape. The system should comprise 3 boxes, the control box (with 21MX inside), a display box with 2 cartridge tape drives, and an A/D box for data acquisition.
