Cost-effective 25 GHz sampling oscilloscopes

16 May 2018 Test & Measurement

The PicoScope 9301 and PicoScope 9341 have received a bandwidth upgrade from 20 GHz to 25 GHz – significant because 25 GHz bandwidth allows five harmonic capture of data rates up to 10 Gbps.

With serial data streams up to 10 Gbps now commonplace, standards such as HDMI 2.0, PCIe Gen2 and Gen3, GBit Ethernet and USB 3.1 Gen1 and Gen2, to name but a few, all have transmission lines, cables, components, transmitters and receivers which all need pre-compliance testing and characterisation.

Engineers need to constantly test and validate their designs before compliance testing. For most companies, owning a real-time scope with 25 GHz bandwidth is unrealistic (upwards of R2 600 000) so long-term renting is often the only way forward, but that could be in excess of R195 000 per month. According to local supplier, Comtest, the new PicoScopes allow users to own a 25 GHz scope for the equivalent of one month’s rent of a 25 GHz real-time scope.

All PicoScope 9300 and 9300-25 sampling oscilloscopes use PicoSample 3 software. The latest release, PicoSample 3.25, includes masks for USB 2.0 and USB 3.1 Gen1 and Gen2, and the user interface has been optimised for use with a mouse or a touchscreen PC or laptop.

No oscilloscope measurement system is complete without a set of high-performance probes, and Pico Technology now offers a full range of highly cost effective microwave and gigabit probes, ideally suited to low-invasive, in-system probing of analog, pulse, impulse and high-speed serial data streams.
