The AC performance of an analog-to-digital converter depends on its architecture. In part 3 of this series, we discussed the integral nonlinearity (INL) error of an analog-to-digital converter (ADC), noting that gain, offset, and INL error all contribute to the total unadjusted error. This metric provides an overall view of an ADC’s DC performance. Q: What about the AC […]

Understanding ADC specs and architectures: part 3
Integral nonlinearity tracks the cumulative effects of an ADC’s differential nonlinearity. In part 2 of this series, we discussed several sources of error in an analog-to-digital converter (ADC), including gain, offset, missing-code error, and differential nonlinearity (DNL). We concluded with an illustration of a waveform with varying levels of DNL superimposed on the staircase representing […]
Automotive data logger syncs timestamps below 100 ns
TTTech Auto announces the launch of the PM-350, the latest addition to its Automotive Data Logger family, designed specifically for Software-Defined Vehicle (SDV) verification and validation. Optimized as a new addition to the Automotive Data Logger family for SDVs, advancing the latest evolution of PM-200, the PM-350 represents the latest innovation in capturing high-speed automotive […]
Modular system combines DMM with DAQ
The DAQ3120 from B+K Precision lets you install up to three measurement modules to create a custom system for your bench. Most engineers have a digital multimeter (DMM) for basic measurements such as voltage, current, and resistance. Sometimes, however, you need the flexibility to add channels and log measurements without or without a computer. That’s […]
USB DAQ system reaches 20-bit resolution
The mioDAQ from NI has two 20-bit and two 16-bit flavors. Analog outputs come with two or four, with 16-bit DIO and counters. USB data-acquisition (DAQ) devices have been on the market for many years and come in many varieties. What makes the mioDAQ series from NI different is its 20-bit vertical resolution on two […]
Optimize AI network design at 800 Gbps
Keysight Technologies, Inc. has entered the artificial intelligence (AI) and machine learning (ML) infrastructure ecosystem with the introduction of the Keysight AI Data Center Test Platform, designed to accelerate innovation in AI / ML network validation and optimization. The solution significantly improves the benchmarking of new AI infrastructures with unprecedented scale and efficiency. The deployment and […]
High-speed digitizer cards perform on-board summation averaging
A new firmware option has been created by Spectrum Instrumentation that allows the company’s high-speed M5i.33xx series of PCIe high-speed digitizers cards to perform on-board summation averaging. Averaging is a useful tool for reducing unwanted signal noise, while at the same time improving measurement resolution, dynamic range and signal-to-noise ratio (SNR). The new option enables […]
Automotive data logger captures multiple data streams simultaneously
The X2E XORAYA Z7 Automotive Datalogger can record data from multiple different automotive bus systems simultaneously. All data is logged with a precise, central timestamp with 100-nsec resolution and either saved on the internal SSD or transferred to an external computer system via Ethernet. Optionally, the logged data can be stored on a XORAYA external […]
Dual-channel digitizers provide synchronous 3.2 GS/sec, 12-bit sampling on each channel
A new dual-channel digitizer provides synchronous 3.2 GS/sec, 12-bit sampling on each channel. This means no data needs to be lost, even when the card is acquiring data with both channels running at their maximum sampling rate. The ultrafast bus allows all the data to be transferred directly to PC memory for storage, or even […]
Digitizer cards stream data over PCIe bus at 12.8 GB/sec
Two new PCIe Digitizer cards from Spectrum Instrumentation bring next-generation performance to PC-based instrumentation. Using 16-lane, Gen 3, PCIe technology, the cards are capable of streaming acquired data over the bus at a staggering 12.8 GB/sec. That is nearly twice as fast as any other PCIe Digitizer currently on the market. Furthermore, it allows the […]
