I purchased this unit for the box and power supply, but now I hate to dissemble it. Dallas Instruments was acquired by Lansmont.com which was acquired by Pira/Ciba Expert Services I think, not much trace of the company or product left on the web.
It appears to connect to a PC parallel port with either external trigger or internal trigger at 10Khz,40K,1K,or 250 Hz. 4 channels muxed with a ADG526 latched analog mux and one 12bit AD7880 A/D converter.
Does anyone have software or info about this box ? I have the data sheets for the two chips above, looks like it could only support one channel at the 40Khz level as the A/D throughput is 66 Khz. Channel 1 has a different op amp and looks like it had +24 or -12 to +12 range.
