The 3425 kit is packaged in a tough carry case and
includes all the accessories you need:
• Four screened BNC to 4 mm plug leads
• 4 current clamp adaptors
• 2 test probes
• 8 large crocodile clips
• USB cable
• Software and Reference CD
• Quick Start Guide
The PicoScope 3425 has powerful display and analysis capabilities:
• Multiple scope and spectrum views
• Automatic measurements
• Data export in text, binary and graphical formats
• Waveform buffer for storing multiple events
• Mask limit testing
• Serial data decoding
• Spectrum analysis
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. 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.
