De Picoscope 3425 Differentiaal USB ossilloscoop is ideaal voor de gebruiker die aan zwevende of niet ground gerefereerde signalen moet mwten.

PicoScope 3425 Differentiaal USB oscilloscoop

Moet u aan zwevende of niet groundgerefereerde signalen meten?
Moet u signalen meten waar een 50 Hz of 60 Hz common-mode noise aanwezig is?
Met de PicoScope 3425 differentiaal oscilloscoop kunt u dit doen zonder dat u hiervoor dure differentiaal preamplifiers of probes nodig heeft.

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 400 V, 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.

Everything you need to take differential measurements
The PicoScope 3425 USB Oscilloscope comes in a tough carry case complete with all the probes, leads, clips and adaptors you need to start taking differential measurements (see the specifications for full details of the supplied hardware and software). Just install the user-friendly software, connect the oscilloscope to a USB port on your Windows PC and you’re ready to go. No complicated set up procedures. No effort required.

take it with you wherever you go
The PicoScope 3425 doesn’t need to be confined to your lab or workbench. Its small, lightweight design makes it the perfect portable differential oscilloscope, while the anti-slip case means that your scope can be used either horizontally or vertically – ideal when space is at a premium.

Powerful oscilloscope and DAQ software
The PicoScope 3425 comes complete with our feature-rich PicoScope 6 oscilloscope software. Multiple scope and spectrum views, automatic measurements and a waveform buffer for storing multiple events can all be controlled using the familiar Windows interface. Data from PicoScope can be exported in text, binary and graphical formats.

PicoLog data acquisition software is also included along with a software development kit (should you wish to use your PicoScope 3425 in your own applications).

The easy and inexpensive 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.)
