Pico Technology Introduces Computer Controlled High-Resolution Deep-Memory Oscilloscopes

Pico Technology, a provider of innovative, cost-effective alternatives to traditional test equipment and data acquisition products, has recently introduced the PicoScope 4000A Series - A series of high-resolution deep-memory oscilloscopes. Most digital oscilloscopes still use an analog trigger architecture based on comparators. This can cause time and amplitude errors that cannot always be calibrated out. The use of comparators often limits the trigger sensitivity at high bandwidths and can also create a long trigger rearm delay. Pico pioneers in the use of fully digital triggering using the actual digitized data.

The PicoScope 4000A Series of PC oscilloscopes is a second-generation upgrade and expansion of their high-resolution, deep-memory product portfolio. With 2, 4 and 8-channel models available, the PicoScope 4000A Series boasts 12-bit hardware resolution (to 16 bits with Resolution Enhancement), 256 MS deep capture memory, 20 MHz bandwidth with 80 MS/s sampling speed, up to 70 dB SFDR and a built-in 14-bit triggerable signal generator and 80 MS/s AWG. A SuperSpeed USB 3.0 interface powers the instrument and delivers up to 160 MS/s communications to the host PC. All models run with the popular PicoScope 6 user interface and benefit from the free PicoSDK software development kit, which gives users direct programming control of the hardware for custom applications. The scopes also work with PicoLog 6 data logging software for lower-speed long-duration captures.

Why choose the PicoScope 4000A Series oscilloscopes?

The PicoScope 4000A Series provides 20 MHz bandwidth, low noise, 12-bit resolution, deep capture memory and an integrated function and arbitrary waveform generator in a compact USB 3 connected PC-based package, together with a proven user interface. This series of oscilloscopes is especially suited to engineers, scientists and technicians working on a wide range of electrical, mechanical, audio, lidar, radar, ultrasonic, NDT and predictive maintenance systems who need to make precise measurements and analysis of repetitive or single-shot long-duration waveforms.

The PicoScope 4000A Series is unlike conventional oscilloscopes with 8-bit resolution and limited capture memory or card-based digitizers that require an expensive mainframe and offers the following benefits:

  • PicoScope 6 user interface with time- and frequency-domain waveform views
  • Automatic measurements of important waveform parameters on up to a million
  • waveform cycles with each triggered acquisition using DeepMeasure
  • Decoding of 18 popular industry serial bus standards.
  • An application programming interface that provides direct control of the hardware
  • Five years warranty included as standard

All models have a built-in low distortion, 80 MS/s, 14-bit arbitrary waveform generator (AWG), which can be used to emulate missing sensor signals during product development. The included PicoSDK allows users to write their own applications and includes drivers for Windows, macOS and Linux.
