FieldDAQ captures physical data close to the sensor

July 1, 2025 By Martin Rowe Leave a Comment

FieldDAQ modules accept sensors directly and send data over Ethernet. Collecting data such as temperature, strain, and other physical parameters often requires long sensor wires or rugged equipment close to the measurement source. Long wires can add errors due to losses in analog wiring or from outside interference. Field installations often add environmental and power […]

Teardown: HP 8112A pulse generator

May 13, 2025 By Martin Rowe 1 Comment

This 50 MHz pulse generator was built as solid as a rock. It’s almost all metal. We take the unit completely apart and look at it from a system and board level. On a visit to the MIT swapfest in 2024, I came across an HP 8112A 50 MHz pulse generator. For $20, I brought […]

OFC 2025: Test equipment

April 21, 2025 By Martin Rowe Leave a Comment

This year’s OFC in San Francisco featured one thing, or so it seemed: 1.6T. Every company making optical modules was showing them lest they be left behind in the always accelerating data rate race. As with any emerging technology, test equipment must lead the way. After all, how do you know if anything works unless […]

VSON package modulators measure 3.5 mm x 2.7 mm

April 7, 2025 By Redding Traiger Leave a Comment

Texas Instruments (TI) introduced the industry’s first functionally isolated modulators, helping designers achieve more precise motor control in compact robot designs. The new AMC0106M05, AMC0136, and AMC0106M25 isolated modulators enable increased precision and higher resolution of 12 to 14 effective number of bits (ENOB) for accurate and reliable phase current sensing and DC voltage sensing […]

Engineers use AI/ML to improve test

December 3, 2024 By Martin Rowe Leave a Comment

AI/ML used to test circuits

Engineers can use AI/ML to reduce test development time, analyze test data from manufacturing, automate visual inspection and calibration, and identify counterfeit components. Here’s how some do it. Testing takes too much time; just ask any engineering or production manager. Shortening test-development time can reduce time to market. Shortening production test time lowers manufacturing costs. […]

Pickering upgrades single-slot PXIe system controller

November 15, 2024 By Aimee Kalnoskas Leave a Comment

Pickering Interfaces announced its next-generation single-slot PXIe embedded controller (model 43-920-002) – the most compact and powerful 3U one-slot embedded controller available for the PXI Express platform. Debuting at electronica, the world’s leading trade fair for the electronics industry, the new module builds on Pickering’s existing controller offering. Pickering’s model 43-920-001, its first PXI embedded controller, was the […]

Isolated current probes eliminate ground loops

November 15, 2024 By Martin Rowe Leave a Comment

Tektronix IsoVue Isolated current probe

IsoVu isolated current probes from Tektronix isolate oscilloscopes from circuits used for EVs, motors, and power converters. Trying to make shunt-based current measurements with a typical oscilloscope probe is essentially impossible. That’s because one side of the probe connects to ground through the instrument. Using an ungrounded power cord is anything but safe. Differential probes […]

How to determine noise figure: part 2

November 13, 2024 By Rick Nelson Leave a Comment

The relationship between noise and temperature prompted a precursor of the IEEE to promulgate an alternative definition of noise figure in 1959. In part 1 of this series, we described the work of the Danish-American radio engineer Harald Friis, who described noise factor F of a device or system as the ratio of the input-power […]
