The PicoScope 4444 with PicoConnect® probes: a new standard in differential measurement

With four true differential inputs, 12- to 14-bit resolution and wide differential and common-mode voltage ranges, the PicoScope 4444 and its accessories offer accurate and detailed measurement for a multitude of applications. The 9-pin D-type connectors provide a true differential probe interface, and also allow the PicoScope 6 software to automatically identify the probe and select the appropriate display settings.

1:1 differential probes

With most oscilloscopes, just connecting to the signal of interest can be very frustrating when one of the connection points has to be grounded. With the PicoConnect® 441 1:1 differential voltage probe, the PicoScope 4444 high-resolution differential oscilloscope allows you the freedom to connect to and visualize signals that are off-limits to a grounded-input oscilloscope. Connect directly to current-sensing resistors and differential signals, or across non-grounded components in a signal path.

The PicoConnect 441 probe does not attenuate your signal and is well suited to numerous electronics applications, as well as biomedical and other scientific research, as it allows high-speed high‑resolution measurements on signals between ±10 mV and ±50 V in the presence of common-mode voltages and noise.

Supplied with detachable black and red sprung hook probe tips.

1000 V CAT III differential probes

Testing and characterization of power supplies can present the oscilloscope user with many challenges, such as hazardous voltages (often floating without reference to ground), feedback circuitry with electrical isolation, and a wide range of signal levels.

One wrong connection of a ground lead and sparks can fly! Using the PicoConnect 442 1000 V CAT III differential voltage probe with the PicoScope 4444, you can easily connect to and visualize the wide range of signals that need to be characterized.The PicoConnect 442 probe has a 25:1 attenuation ratio and is suitable for testing in a range of applications, including distribution boards, circuit breakers, junction boxes, switches, fixed socket outlets and industrial equipment such as permanently connected stationary motors.

Supplied with detachable shrouded black and red sprung hook probe tips.

Oscilloscope kits

We and our distributors supply three preconfigured kits with everything you need to get started with differential measurement. Each kit includes a PicoScope 4444 high-resolution

differential oscilloscope and three differential voltage probes with Pico D9 connectors. The kits also come with a TA271 D9‑BNC adaptor, which lets you use traditional oscilloscope

voltage probes and current probes, to make single-ended measurements with a ground-referenced probe. Finally, all three kits are delivered in a sturdy carry case, as shown below.

These and a range of other accessories are also available separately.

Extra low voltage differential kit
