At only USD14,995, these two-channel oscilloscopes are aimed to replace traditional, full-sized bench-top instruments. These small footprint full-featured PC-based sequential sampling oscilloscopes can be positioned right next to the device under test, minimizing cable losses and removing the need for expensive active probes or pull-out sampling modules. The built-in signal generator features a 4 ns minimum bit interval in PRBS mode and 8 ns minimum period in pulse mode. The devices have LAN and USB interfaces, and advanced display features such as colour and density profiling, multiple trace windows, histograms and statistics.

The instruments support over 15 TS/s of effective sampling rate, have a 17.5 ps input rise time, feature dual 16-bit, 60 dB dynamic range inputs, and a 5 ps/div dual timebase. They come with a 14GHz prescaled trigger bandwidth, a clock recovery up to 11.3 Gb/s and a time interval resolution of 64 fs. The sampling rate of 1 MHz builds waveforms and persistence displays faster than any other sampling scope, claims the manufacturer. Typical noise is 1.5 mV RMS at full bandwidth, external trigger jitter is 1.8 ps RMS, and recovered clock jitter is only 1 ps RMS.

The PicoSample software has been comprehensively updated for the new oscilloscopes. The range of controls has been revised and extended, with intuitive graphics, click-and-drag operations and measurement labels to simplify and speed up operation. The software features a comprehensive suite of measurement and analysis functions including 61 math functions, 138 automatic measurements and 167 standard comms masks from 1.54 Mb/s to 12.5 Gb/s.
