A novel chipset and architecture for portable oscilloscopes

Three chips compose the Phoenix chipset (each named after stars in the Phoenix Constellation).

The Analog Front-End Chip (named Beta Phoenicis) will allow for front end bandwidth as high as 4 GHz, and integrates all functionality required by a digital oscilloscope’s analog modules, including a 1 MΩ channel input attenuator; the chip needs only to add a few external components to form an oscilloscope’s analog front-end channels.

A signal processing chip (named Ankaa) supports 10 GSample/sec data acquisition capability with bandwidth up to 6 GHz and is complemented with the probe amplifier chip (named Gamma Phoenicis) which will support differential probes up to 6GHz.

All three ASICs were developed in-house, entirely based on Rigol’s IP.

The company expects its Phoenix chipset and UltraVision II architecture to enable instruments with significantly faster waveform capture rates, new filtering and triggering capabilities, and unprecedented memory depths and search capabilities. Rigol has built a prototype scope based on Phoenix and Ultravision II, boasting a 4 GHz bandwidth, 20 GSample/sec real-time sample rate and 1 billion point memory depth.

 

The product line will, Rigol says, transfrom its profile in this scope sector; products will be announced within 2017, with first shipments in the fourth quarter of the year
