Data acquisition card for varian electron paramagnetic resonance spectrometers

Abstract

Abstraet. An easy to assemble and inexpensive PC card that interfaces E-Line Varian spectrometers (E-6, E-9, E-12 and E-15) with IBM compatible PCs is presented. The card has a Programmable Interval Timer so it does not need an extemal clock making it instrument independent. The accessory contains its own RAM. This allows the device to store the spectrum while sampling is in progress, so the PC can meanwhile be used for any other task.
