Saelig has introduced the PS4227, a two-channel 100MHz precision USB oscilloscope with a real-time sampling rate of 250MSa/s that is suitable for general, scientific and field-service use.

With 12-bit resolution – adjustable up to 16 bits in enhanced resolution mode for repetitive signals – it also makes a suitable A/D choice for noise, vibration and mechanical analysis.

Powered from a PC’s USB port, PS4227 includes an integrated spectrum analyser, function generator and arbitrary waveform generator – a complete test and measurement laboratory that is small enough to take anywhere.

With two 12-bit input channels and a bandwidth of 100MHz, detailed waveforms can be captured for production testing, scientific analysis, electronic design and debug tasks.

A third input is a dedicated external trigger, while a fourth BNC connector is provided for the output of the signal generator.

This signal source allows the user to create an arbitrary test signal, draw their own waveform using the graphical editor, or use one of the six preset waveform types.

PS4227 can sample at rates up to 250MS/s, and has a large 32megasample buffer memory, allowing the maximum sampling rate to be used even on slow time-bases.

The buffer can hold up to 10,000 waveforms, viewable in an easy-access pop-up navigator window.

Picoscope oscilloscope software is included, which provides a range of advanced functions such as mask limit testing, alarms, serial data decoding, programmable low-pass filtering, math channels, reference waveforms, digital colour and analogue persistence display modes and XY mode.

Advanced trigger selections include pulse width, window interval, dropout, and runt pulse.

PS4227 is powered from the USB 2.0 interface, removing the need for an external power supply.

A USB2.0 port allows high-speed data to be delivered to the host PC to give a responsive, high-resolution display.

With up to 250MS/s real-time sampling, PS4227 is claimed to be the fastest USB-powered 12-bit scope on the market.

As well as a fully-functioning oscilloscope with advanced features such as digital persistence, math functions and automated measurements, Picoscope software provides spectrum analyser, function generator and arbitrary waveform generator functionality.

A free software development kit containing software drivers and example code is also provided, and unlimited free software updates can be downloaded as they become available.

PS4227, made by Pico Technology, comes with a five-year parts-and-labour warranty.
