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 […]

Modular tester simulates and tests control systems
The Pulse Real-Time Target Machine from Swiss company Speedgoat uses a set of I/O modules so you can configure s test system that meets your needs.
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 […]
APEC 2025 test equipment: power sources and loads
Powering electronic devices requires the testing of power supply and charging circuits, battery management systems (BMSs), and battery cells. Many of these circuits require voltage, current, and power measurements, plus numerous others. Oscilloscopes and probes let you see the waveforms in power-delivery circuits, but the circuits themselves may need simulated batteries and simulated loads. That’s […]
Ethernet/LXI digitizers feature 12-bit resolution and up to 4.7 GHz bandwidth
Spectrum Instrumentation has introduced seven new digitizers in the DN2.33x series for signal acquisition and analysis in the GHz range. The devices connect via Ethernet/LXI interface to computers or networks and are designed for both R&D and industrial applications. The DN2.33x series digitizers utilize ADC technology with sampling rates between 3.2 GS/s and 10 GS/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 […]
Emerson acquires NI: There goes another one
NI will now join the long list of T and M companies whose names we’ll see only online, on eBay, and at electronics flea markets. Product names such as LabVIEW should live on.
Functional tester covers bench, production, and service applications
The midUTS from Bloomy contains a multimeter, data-acquisition, switching, and power supplies for testing boards and systems. Automating tests — whether for bench testing new designs, in production, or for service — increases productivity but comes at a price. If you’re going to build an automated test system all yourself, expect to specify the instrumentation, […]
Test data analysis software includes Python interface, supports multi-core PC parallel processing
The new version of data analysis software imc FAMOS 2022 from manufacturer imc Test & Measurement, a brand of Axiometrix Solutions, now integrates a Python interface and supports parallel processing for modern multi-core PC architectures. imc FAMOS offers professional tools for the visualization and analysis of test and measurement data from a variety of data […]
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 […]
