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. They also allow 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 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. 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 setup procedures. No effort required. Its small, lightweight design means the PicoScope 3425 doesn't need to be confined to your lab or workbench. It is 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. The included accessories and easy-to-use software allow you to get the maximum from your PicoScope.
