Understanding ADC specs and architectures: part 4

May 28, 2025 By Rick Nelson Leave a Comment

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

May 21, 2025 By Rick Nelson Leave a Comment

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 […]

Modular system combines DMM with DAQ

March 27, 2025 By Martin Rowe Leave a Comment

DAQ3120

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

September 18, 2024 By Martin Rowe Leave a Comment

NI mioDAQ

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 […]

High-speed digitizer cards perform on-board summation averaging

October 12, 2022 By Lee Teschler Leave a Comment

spectrum instrumentation

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

June 1, 2022 By Lee Teschler Leave a Comment

saelig

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

May 18, 2022 By Lee Teschler Leave a Comment

spectrum instrumentation

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

March 9, 2022 By Lee Teschler Leave a Comment

spectrum instrumentation

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 […]
