4 channel differential oscilloscope

See the difference with the new PicoScope 4444

With four true differential channels, the PicoScope 4444 enables high-resolution measurements of differential voltage waveforms. This oscilloscope eradicates the problem of making accurate voltage waveform measurements on circuit elements that are not ground-referenced, without the risk of short circuits that could damage the device under test or the measuring instrument.

  • 4 channels
  • 20 MHz bandwidth
  • Flexible 12-bit or 14-bit resolution
  • Up to 400 MS/s sampling rate
  • 256 MS capture memory
  • High common-mode rejection ratio
  • Balanced high-impedance inputs for a low circuit load

PicoScope 6.12.9 Beta for macOS

  • Added support for PicoScope 4444 and Pico D9 intelligent probe interface
  • Added enhanced user interface controls for collection time and input range selection
  • Added new serial protocol decoder for CAN FD
  • Added pop-up notifications
  • Redesigned overrange safety warnings
  • Added new built-in probe settings for TA325 and TA326 flex current probes
  • Improved handling of mismatched PicoScope .psdata files

Following the launch of the PicoScope 4444 differential oscilloscope, we’ve added support to enable the oscilloscope and its unique features in PicoScope 6 for macOS. The most significant new feature to be added is support for the Pico D9 intelligent probe interface, which allows a range of Pico D9 probes including current probes, voltage probes and D9-BNC adaptors to be automatically detected when connected/disconnected and set up in PicoScope 6 for macOS to the appropriate range and units.

In previous versions of PicoScope 6, selection of the collection time and vertical scale was from a long drop-down list. The new menu has a modern look and feel, presenting the user with easy access to all ranges, and selecting the range required is now much faster.

The PicoScope software now decodes and displays CAN FD (controller area network with flexible data-rate) data and waveforms, to support the widespread adoption of the standard by the automotive industry and industrial automation. CAN FD packets can contain a maximum payload (data field) of up to 64 bytes, an improvement over the 8 byte maximum of the original CAN.

We have redesigned notification messages to make them less intrusive. The power options dialog, which appeared when devices accepted external DC or USB power, has been replaced with a pop-up notification that no longer requires user interaction. The notification banners now slide in and out of the bottom right corner of the PicoScope window. The latest notification banner to be added informs users when and to which channel Pico D9 supported probes and adaptors are connected and disconnected.

We’ve improved the on-screen overrange safety warnings. Now, an additional overrange symbol is displayed by the axis of the channel whose range has been exceeded, along with a written message for both channel overrange (red) and common-mode overrange (yellow).

Two new current probes have been added to the list of standard probes in the Probe selection menu. The new 1000 V CAT III AC current probes—TA326 single phase flex probe and TA325 3-phase flex probe—are based on Rogowski coil technology and feature three user-selectable current ranges of 30 A, 300 A and 3000 A.

We’ve also improved the way PicoScope handles .psdata files that were saved using a different device from the one they are being opened on.
