Custom ASIC for 14bit precision oscilloscope
Keysight Technologies has developed a custom ASIC for its 14-bit analogue-to-digital converter (ADC) oscilloscope to provide four times the signal resolution and half the noise floor of other general-purpose oscilloscopes
The Keysight InfiniiVision HD3 Series oscilloscope has been designed from the ground up with the custom ASIC and a deep memory architecture for general applications with 14bit resolution, using hardware from the UXR series.
This provides a 50 µVRMS low noise floor that can detect the smallest signal anomalies and covers bandwidths between 200 MHz and 1 GHz with 1.3 M waveforms / second update rate for all measurements.
A new user interface enables full ADC and vertical resolution on every channel, several bandwidth limiting options, HD mode support, and custom measurement thresholds.
Automatic fault hunter software for general debugging analyses glitches and slow edges while engineers complete other tasks. Engineers can also automate measurements with a large selection of serial bus protocols and application software.
Immediate bandwidth, memory, and feature upgrades are possible through software licensing, enabling designers to purchase options they need now and upgrade as their designs evolve in the future without having to return the instrument to the factory.
“Recognising the need of engineers for quick and precise measurements for a variety of applications, we built the InfiniiVision HD3 from the ground up to deliver an exceptionally precise general use oscilloscope. With a custom ASIC, 14-bit ADC, and half the noise floor, the HD3 Series oscilloscope delivers the precision and accuracy needed to identify the smallest and most infrequent signal glitches during design debugging to accelerate time to market,” said Robert Saponas, Vice President and General Manager, Keysight Digital Photonics Centre of Excellence.
