Attention all
Automotive Scope Users

Pico Automotive Scope software now sports a new Waveform Library browser.
Must own PicoScope to view.
See details here


Serial Decoding - UPDATE

The new PicoScope beta release, 6.13, adds Modbus RTU and ASCII to its growing list of serial decoders. Modbus is used in industrial automation to communicate with programmable logic controllers (PLCs).

PicoScope 6 now supports a total of 18 serial protocols and is the only oscilloscope that can decode Modbus.


You can use PicoScope to decode data from a serial bus such as CAN bus. Unlike a conventional bus analyzer, PicoScope lets you see the high-resolution electrical waveform at the same time as the data. RS232/UART and SPI formats added to serial decoding mode

Privacy and Security Policy
Multichannel data loggers offering high resolution, high accuracy and programmable input ranges.


High-resolution data acquisition


  • 24-bit resolution
  • Up to 8 true differential inputs
  • Up to 16 single-ended inputs
  • 7 input ranges (±39 mV to ±2500 mV) 
  • Fast conversion time
  • Digital outputs for control
  • Galvanic isolation from the PC to eliminate noise pickup
  • PicoLog data acquisition software included
  • Software drivers and SDK included

The ultimate in resolution and accuracy

With up to 24-bit resolution the ADC-20 and ADC-24 USB data loggers are able to detect small signal changes. Features such as true differential inputs, galvanic isolation and software-selectable sampling rates all contribute to a superior noise-free resolution and ensure that your measurements are reliable and accurate.

All Pico data acquisition products come complete with PicoLog. This powerful yet flexible data acquisition software allows you to collect, manipulate, analyze, display and export data. With PicoLog you can sample up to one million readings at selectable sampling rates; and using PicoLog, or our driver with your own software, you can connect up to four units to one PC.


Flexible, multichannel data acquisition

Both the ADC-20 and ADC-24 feature true differential inputs for excellent noise rejection. To give you a very flexible system each differential input can also be configured as two single-ended inputs. With up to eight differential or 16 single-ended inputs on the ADC-24, this flexibility gives you complete control on what type of inputs you use. If you require more channels, you can use multiple PicoLog data loggers on the same PC.

With seven bipolar voltage ranges, the ADC-20 and ADC-24 are also flexible enough to be used with a wide range of sensors and signal types. There's also an external terminal board with screw terminals to allow you to quickly connect and disconnect different sensors.

Additionally, the ADC-24 has four configurable digital input/output channels that can be used to control alarms or other devices.

The flexibility of the ADC-20 and ADC-24 allows you to use these precision data loggers as an advanced multichannel data acquisition system with a low cost per channel.

No need for power supplies or batteries

The high-resolution ADC-20 and ADC-24 are powered directly by your PC — eliminating the need for batteries or a separate power supply, and making them ideal when you need a portable data logger.

The answer to your data acquisition needs

High resolution, true differential inputs, galvanic isolation, and selectable sampling rates combine to ensure that your measurements are always precise and accurate. Configurable inputs, digital inputs and outputs, and programmable voltage ranges give you a truly flexible answer to your data acquisition needs.

When you need the ultimate in high resolution and accuracy, the versatile ADC-20 and ADC-24 provide you with a portable answer with the performance and flexibility you need.
