ADC-40/42 Digital Oscilloscopes

pc based oscilloscopes

The ADC-40 and ADC-42 are single-channel digital 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 single-channel oscilloscopes 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.

ADC-40/42 No Longer Available

Please note: the ADC-40 and ADC-42 are no longer available. We recommend the PicoScope 2104/2105 handheld oscilloscopes , or a PicoScope 3224 precision oscilloscope if you need a 12-bit oscilloscope.
