- Keysight Technologies announces the InfiniiVision HD3 series oscilloscopes, featuring a 14-bit resolution analog-to-digital converter (ADC).
- These 2- or 4-channel digital oscilloscopes cover a bandwidth ranging from 200 MHz to 1 GHz, depending on the model.
The development of electronic devices and components requires the examination of signals of ever lower amplitudes, in order to identify the slightest signal errors, signs of possible design faults and hardware failures. Oscilloscopes must therefore be able to digitize signals with increased resolution.
The new HD3 series digital oscilloscope, which covers a bandwidth of 200 MHz to 1 GHz depending on the model, aims to meet this challenge by offering 14-bit vertical resolution, a noise floor of 50 µVRMS over a 1 GHz bandwidth, and a refresh rate of 1.3 million waveforms per second. This can detect even the smallest signal anomalies.
Note that an oscilloscope with a 12-bit ADC can encode an analog input in 4,096 unique conversion levels (2 to the 12th power = 4,096). Each additional bit doubles the number of conversion levels. Oscilloscopes with a 14-bit CAN can code the analog input in 16,384 levels (2 to the 14th power = 16,384). This represents four times the resolution of oscilloscopes with a 12-bit ADC, and 64 times the resolution of an 8-bit ADC.
InfiniiVision HD3 oscilloscopes feature a 10.1” capacitive touch screen. They feature 2 or 4 analog inputs and 16 digital inputs. Depending on the model, they cover a bandwidth of 200 MHz, 350 MHz, 500 MHz or 1 GHz. They sample analog signals at a maximum rate of 3.2 GS/s per channel, and feature a maximum recording memory depth on each analog channel of 20 Mpts (50 or 100 Mpts optional).
The HD3 family of oscilloscopes combines several measurement functions in a single instrument: two- or four-channel analog and 16-channel digital oscilloscope, serial bus protocol analyzer, frequency response analyzer, 100 MHz arbitrary waveform generator, three-digit digital voltmeter and an eight-digit counter with totalizer.
All family models feature frequency response analysis, Fault Hunter, zone triggering, recording memory segmentation, mask testing, FFT calculation and more.
Fault Hunter is an inspection system for digital systems. It automatically evaluates signal characteristics according to user-defined criteria to detect and record errors. The test duration can be adjusted from a few minutes to two days.
Software options are available for triggering and decoding serial [I2C, SPI, UART (RS232/422/485)] and automotive [CAN, CAN FD, CAN XL, LIN] buses.
The oscilloscope’s bandwidth, memory and functions can be immediately upgraded via software licenses. This allows designers to purchase the options they need today and upgrade them as their requirements evolve, without having to send the instrument back to the factory.
