D9 differential voltage probes

The Pico D9 connected range of accessories connect exclusively with the PicoScope 4444 differential oscilloscope. The scope interface also provides power to the accessory.

Choose either the PicoConnect 441 non-attenuated probe for measuring low-amplitude signals, or PicoConnect 442 25:1 attenuated probe for making safe cost-effective differential voltage measurements up to 1000 V CAT III.

PicoConnect 441 - 1:1 differential probe
For use with PicoScope 4444 Series Differential USB Oscilloscopes

The PicoConnect 441 is a general-purpose passive differential probe with 1:1 voltage ratio and 15 MHz bandwidth, for precisely measuring voltages on ranges from ±10 mV to ±50 V. The probe is fitted with a ground reference clip, as well as the usual positive and negative leads, to eliminate unknown common mode voltage differences between the probe and the device under test (DUT). It uses unshrouded 4 mm banana leads, so is compatible with a wide range of test probes. It comes with a pair of sprung hook probes.

This probe is ideal for anyone needing to make lower-amplitude, precision measurements in a wide range of applications. You can also use it to measure the signals on differential serial buses such as CAN and RS-485.

PicoConnect 442 - 25:1 differential probe (1000 V CAT III)
For use with PicoScope 4444 Series Differential USB Oscilloscopes

The PicoConnect 442 probe is a 25:1 attenuating probe that enables the PicoScope 4444 differential oscilloscope to measure large-amplitude voltages up to ±1000 V, or voltages with a large common-mode offset. Such voltages are found in electrical power converters, inverters, motor speed controls, switch mode power supplies and many other devices.

The probe is fitted with the Pico D9 connector for use exclusively with the PicoScope 4444 differential oscilloscope, upon connection it is automatically identified by the scope as a 25:1 probe, and scales the vertical axis in PicoScope 6 software with the correct probe attenuation.

The probe body provides double-insulated protection for the user for CAT ratings up to and including 1000 V CAT III.

The PicoConnect 442 probe is designed and tested to EN 61010-1:2010 General requirements and to EN 61010-2-030:2010 Particular requirements for testing and measuring circuits. The TA089 and TA090 sprung hooks are designed to EN 61010‑031:2015 Safety requirements for hand-held probe assemblies.
