PC oscilloscopes replace benchtop instruments

A Pico Technology product story
Edited by the Engineeringtalk editorial team Nov 12, 2004

Pico Technology has announced a new series of high-performance PC oscilloscopes.

Pico Technology has announced a new series of high-performance PC oscilloscopes.

The 3000 series debuts with three instruments: the Picoscope 3204, 3205 and 3206.

All three are claimed to be cost-effective replacements for traditional bench top instruments.

The oscilloscopes have a claimed sampling rate of 10GS/s, an analogue bandwidth of 200MHz, and a record length of 1Mb.

Alan Tong, Pico Technology's technical director, commented: "The combined high sampling rate and large memory buffer of the Picoscope 3206 enable the capture and display of fast-occurring and complex signals.

Most oscilloscopes in the same price bracket as the 3206 have sub-32K memories.

With 1Mb of memory, the 3206 can capture at least 30 times as much data, allowing the user the ability to zoom in on areas of interest." All three Picoscopes in the 3000 series connect to a PC via USB2.0: drawing their power from the PC, so no need for a separate power supply.

In addition to being high- performance oscilloscopes, the Picoscope 3204, 3205 and 3206 all feature a spectrum analyser mode and (when used with Picolog software) can also be used for high-speed data acquisition.

The 3205 and 3206 also include built-in signal generators, capable of sweeping up to 1MHz.

The signal, output on the oscilloscopes' 'external trigger' BNCs, can be a sine, square or triangular wave.

The Picoscope 3000 series features more than 30 automated measurements such as: frequency; pulse width; rise time; THD and SNR; and five enhanced display modes including Digital Colour (ideal for spotting intermittent glitches in digital signals) and analogue intensity (useful for displaying video waveforms and analogue modulation signals).

Tong concluded: "Essentially, we've repeated our well-proven formula of making full use of today's PCs' processing capabilities, large screens and familiar user interfaces, and focused our efforts on developing signal acquisition techniques, enhanced display modes and automated measurements." The three new Picoscopes are available immediately and are supplied with Picoscope and Picolog software and demonstration and full versions can be downloaded free of charge from Pico's web site.

The 3204 retails for ?399 + VAT, the 3205 for ?599 + VAT and the 3206 for ?799 + VAT.
