Introduction
The PICO ADC-100 and ADC-101 are medium speed analog to digital converters with two analog input
channels and programmable input voltage ranges. They can be used as a virtual instrument (oscilloscope,
spectrum analyser and meter) with the PicoScope program, or as a data logger using PicoLog. Alternatively,
you can use the ADC-100 driver software to develop your own programs to collect and analyse data from
the unit.
This manual describes the physical and electrical properties of the ADC-100 and ADC-101, and explains
how to use the Windows software drivers. For information about the software supplied with the unit, please
refer to the following documents:
PicoLog for Windows
PicoScope for Windows
DOS drivers

Connecting to the PC
To use the ADC-100, you should connect the D-connector on the ADC-200 to the printer port on your
computer using the cable provided.
The ADC-100 has the same connectors as an oscilloscope, so you can use standard oscilloscope probes.
The input impedance is also the same, so the x10 function on a scope probe works correctly.
To check that the unit is working, start up PicoScope. PicoScope should now display the voltage that you
have connected. If you are using scope probes, when you touch the scope probe tip with your finger, you
should see a small 50Hz mains signal.
The ADC-100 works correctly on most computers, however some computers (mainly laptops) have non
standard printer ports. If you are having trouble, you will need to use the special adaptor which plugs into the
cable between the computer and the ADC-100. The software automatically detects the adaptor, provided it
is plugged in before the program is started. The adaptor is supplied with the ADC-100, the ADC-101 has the
adaptor built in.
