The new PicoScope 3425 is a brand new PC Oscilloscope from Pico Technology, featuring four differential inputs, 12-bit precision, 5 MHz bandwidth and a high-speed USB 2.0 interface. A fully documented programming interface is included, with example programs in C, C++, Visual Basic, Excel and LabVIEW.

The PicoScope 3425’s differential inputs allow you to measure signals that are not referenced to ground, removing the need for expensive differential preamplifiers and probes. Its maximum common mode and differential ranges of 400 V make it ideal for capturing power waveforms from switch mode power supplies and motor inverters. It is also perfect for use in physics and biology laboratories, where its ability to reject common-mode noise allows it to pick up low-level differential signals from sensors.

The PicoScope 3425 has 12-bit resolution and a 20 megasample per second sampling rate, allowing it to capture extremely detailed waveforms, and its input impedance of over 10 megaohms puts minimal load on the circuit under test. It is USB-powered and requires no external power supply.

The PicoScope 6 software, included with the scope, can show multiple views of the signal with different offsets and scales, in addition to a range of automatic measurements. The scope’s timebase range is 500 nanoseconds to 5 seconds per division, and with its deep memory of 512 K samples it can capture 26 milliseconds of data at its top sampling rate. A high-speed streaming mode allows the scope to capture large data sets limited only by the PC’s memory, and resolution enhance mode can boost the scope’s effective resolution to 16 bits. The software also has a spectrum analyser mode that can show frequency- and time-domain data at the same time.

Alan Tong, Managing Director of Pico Technology, commented:
“Our PicoScope 3000 Series of scopes is already well-known for its high performance and ease of use. The PicoScope 3425 builds on that reputation, and opens up the benefits of PC Oscilloscopes to a new class of users.”

The PicoScope 3425 differential input oscilloscope is available from local distributors, or direct from Pico Technology at www.picotech.com, for £975 + VAT and delivery.
