4-Channel Precision PC Oscilloscope - USB 2.0

High resolution and accuracy

With 12 bit resolution and 1% accuracy, the PicoScope 3425 is able to detect changes as small as 0.024% (244 ppm) — making it the ideal 4-channel oscilloscope for testing audio circuits, and for measuring noise and vibrations.

High dynamic range

When the PicoScope 3425 is used as a spectrum analyzer its high, 72 dB, dynamic range makes it the ideal tool for tracking down noise in sensitive analogue circuits.

Capture large and complex signals

The 512,000 sample buffer of the PicoScope 3425 enables large amounts of data to be captured at high sampling rates. This allows you to capture fast-changing signals over relatively long periods of time, while the fast USB 2.0 interface ensures a quick screen update rate. After capturing these signals, any areas of interest can be magnified to allow you to examine every last detail of the signal.

Differential Input

Most oscilloscopes can only measure signals referenced to ground and have what are known as “single ended inputs”. The PicoScope 3425 has four fully differential inputs that allow you to measure signals that are not referenced to ground.

With a maximum common mode and differential range of 400V, the PicoScope 3425 is capable of measuring both high voltage and low level signals. Typical high voltage applications include capturing waveforms from switch mode power supplies, telephone cables, motor inverters and hybrid vehicles. The high impedance differential inputs also allow measurements on sensitive amplifiers and from bridge type sensors for pressure, load and strain.

The easy/cost-effective way to measure floating voltages

The PicoScope 3425 differential USB oscilloscope allows you to measure floating voltages, and signals where common-mode noise is present, with ease and without the need for expensive differential preamplifiers or probes. The maximum common mode and differential range of 400 V ensures the PicoScope 3425 is suitable for many common applications; while the included accessories and easy-to-use software allow you to get the maximum from your PicoScope, with the minimum of effort.

If you’re looking for an easy and cost-effective way to measure non-ground referenced high voltages or low level signals in the presence of common-mode noise, you need a PicoScope 3425 differential oscilloscope.

Note: The PicoScope 3425 is rated as measurement category CAT I – for measurements performed on circuits not directly connected to mains. (If you need to make mains measurements we have a CAT III differential oscilloscope probe.)

The PicoScope 3425 is supplied with PicoScope software that provides oscilloscope, spectrum analyzer and multimeter functions. PicoScope software makes full use of your PC's processing capabilities allowing you to view real-time signals, zoom in on your signal, and save and print captured waveforms. The familiar Windows graphical interface makes PicoScope intuitive to use and includes an autosetup function that will automatically set up the timebase, channels and trigger configuration to display any signals that PicoScope finds on the oscilloscope's inputs.

Also supplied is PicoLog data acquisition software that transforms your PC into a high-speed data logger.
