Pico Technology PicoScope 4000 Series, 20 MHz PC Based Oscilloscope 4-Channel

The PicoScope 4444 and its accessories offer accurate and detailed measurement for a multitude of applications. At the heart of every PicoScope 4444 is an advanced oscilloscope that offers everything you would expect and much more, including:

4 fully differential high-impedance inputs

Non-ground-referenced measurements

With a traditional oscilloscope probe, single-ended measurements are made between a high-impedance input and a low-impedance ground.;With a differential oscilloscope, measurements are made between two high-impedance inputs, allowing measurements to be made across components and test points where neither side is grounded. Differential inputs also reject common-mode noise: noise picked up equally on both high-impedance inputs is rejected.;Each of the four input channels on the PicoScope 4444 features an intelligent probe interface that detects and identifies compatible probes, and powers them where necessary. Each channel can have its own choice of voltage or current probe.;Non-attenuating probes allow high-resolution, low-noise measurement of signals ranging from millivolts to ±50 V. Attenuating probes allow signals up to 1000 V CAT III to be measured. Current probes are available for currents up to 2000 A.
