What is the purpose and capabilities of the Pico ADC-200?
The PICO ADC-200 is a high speed analog to digital converter with two input channels and software controlled input ranges. It can be used as a virtual instrument with the supplied PicoScope software, or you can use the ADC-200 driver software to develop your own programs to collect and analyse data from the unit.
What safety warnings should be observed when using the Pico ADC-200?
For all Pico ADCs, the ground input (BNC outer shell) is connected directly to the ground of your computer. This is done in order to minimise interference. As with most oscilloscopes, you should take care not to connect the ground input of the ADC to anything which may be at some voltage other than ground; doing so may cause damage to the ADC. If in doubt, connect a channel input to the doubtful ground point and check that there is no significant AC or DC voltage.
As some computers do not have an earth connection (for example laptops), it must be assumed that the ADC-200 is not protected by an earth. For this reason, only Class II (double insulated) oscilloscope probes should be used.
The maximum input voltage of the ADC-200 is ±20V. Any voltages in excess of ±100V may cause permanent damage to the unit.
What are the limitations regarding user serviceability of the Pico ADC-200?
The unit contains no user serviceable parts. Repair or calibration of the unit requires specialised test equipment and must be performed by Pico Technology Limited or their authorised distributors.

What items should be included in the ADC-200 package?
The ADC-200 package should contain the following items:
ADC-200 unit
25 way parallel cable
Power supply
Software diskette
ADC-200 manual
PicoScope for DOS manual
How do I install the software for the Pico ADC-200 under DOS?
To install the software under DOS:
1. Insert the diskette into drive A.
2. Type A:INSTALL and press Enter.
How do I install the software for the Pico ADC-200 under Windows?
To install the software under Windows:
1. Insert the diskette into drive A.
2. Select File from the program manager menu.
3. Select Run from the File sub-menu.
4. Type in A:WINSTALL and press Enter.
Where is the software typically installed on the computer?
The software will normally be installed in a directory called C:\PICO and the software drivers in the sub-directory called C:\PICO\DRIVERS.
How do I connect the ADC-200 hardware to my computer and power it?
To use the ADC-200, you should connect the D-connector on the ADC-200 to the printer port on your computer using the cable provided. Next, connect DC power by plugging the power adaptor into a mains socket and plugging the DC power jack into the socket on the ADC-200. The red light should now be on, showing the unit is powered.
What type of oscilloscope probes can be used with the ADC-200?
The ADC-200 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.
How do I switch between AC and DC voltage measurements on the ADC-200?
There is a switch next to each BNC connector. With the switch down, the ADC-200 can measure DC voltages on the BNC next to it. With the switch up, it measures only AC voltages.
What are the functions of the BNC connector labeled ‘E’ on the ADC-200?
The BNC connector labeled ‘E’ has two functions:
1. In normal use, it is the external trigger input and accepts a TTL compatible input signal.
2. This connector can also be used as a simple (squarewave) generator. This signal generator can be used to compensate x10 scope probes.
How can I check if the ADC-200 unit is working correctly?
To check that the unit is working, start up the PicoScope program. 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 on the screen.
