ADC-40 Oscilloscope $85

 ADC-42 Oscilloscope $140


The ADC-40 and ADC-42 are single channel PC based oscilloscopes, spectrum analysers and multimeters. Simply plug a unit into the parallel port
of your PC and run the supplied PicoScope software. For low frequency signals, the units provide all the functionality of conventional scopes at a
fraction of the price. The ADC-40 has 8 bit resolution, whilst the ADC-42 has a 12 bit resolution which makes it more suitable for measuring small
signal changes, both on the scope and spectrum analyser. 
These two products are ideal for situations where budget is important. The units provide large, colourful displays and
all the usual timebases and trigger options, all in a case slightly larger than a matchbox. These features, combined with
their low cost, make the ADC-40 and ADC-42 perfect as educational and training tools. For an independent review by
 Technical specifications are listed at the bottom of this page.

This one might be a bit better as it has 12 bit resolution for not much more money.
