Can something consume energy without emitting a field?

April 29, 2022 By David Herres Leave a Comment

em fields

The editorial offices of Testandmeasurementtips.com recently received a letter from an individual who headed up a group of investigators of paranormal phenomenon. It was a serious letter. To summarize, the group had concluded there was no legitimate method to record the activity of an alleged haunting. But the writer did have a question for us, […]

Radio altimeter flight-line test set adds fiber optic delay

April 27, 2022 By Lee Teschler Leave a Comment

viavi

The ALT-9000 universal radio altimeter (RADALT) flight line test set adds fiber optic delay to traditional radio frequency (RF) testing, enabling it to test all types of RADALTS on the market today. The RADALT measures an aircraft’s altitude above the terrain, by transmitting a radio frequency (RF) signal down to the ground and receiving a […]

How big is the band gap? A heated discussion

April 22, 2022 By David Herres Leave a Comment

There’s a trick with a soldering iron that can be used to determine whether an unidentified semiconductor is n-type or p-type. In essence, it determines whether the majority carriers are holes (p-type) or electrons (n-type). Just as heat makes a gas expand (PV=nRT), the hot tip of a soldering iron makes carriers expand away from […]

Test setup simulates, characterizes, validates PCIe designs

April 5, 2022 By Lee Teschler Leave a Comment

keysight

An end-to-end PCIe test solution enables the simulation, pathfinding, characterization, validation and compliance testing of PCIe designs. To maintain performance goals and prepare for the PCIe 6.0 move to pulse amplitude modulation 4-level (PAM4), customers need a smooth transition from PCIe 5.0 to 6.0, where the integrity of PCIe measurements are backed by leading-edge tools […]

High-voltage probe provides isolation via fiber optics

April 5, 2022 By Lee Teschler Leave a Comment

saelig

The Saker-MV ISOVP Probe enables high-voltage isolated measurements via fiber optic cables. Optical fiber isolation provides high-voltage safety and increased signal integrity due to absence of induced interference from external fields. This also allows for much higher common mode rejection as compared to conventional differential probes. The probe head can be remotely put in standby, […]

What is Fourier transform IR spectroscopy?

March 18, 2022 By David Herres Leave a Comment

FTIS

Most EEs probably think of a Fourier transform in terms of an operation that converts time-based waveforms on a scope into their component frequencies. But Fourier transforms also play a role in infrared spectroscopy. It might be easiest to explain Fourier transform infrared spectroscopy by contrasting it with conventional spectroscopy. Also called “dispersive spectroscopy,” the […]

Ohm meter features low stimulus voltage for sensitive components

March 17, 2022 By Lee Teschler Leave a Comment

saelig

The AltoNovus OR-01 OhmRanger-LCV Low Compliance Voltage Ohmmeter is an accurate, affordable, portable meter which can measure a wide range of resistances simply and quickly. Individually factory-calibrated, this meter measures resistances from greater than 100 MΩ down to 10 Ω. Additional built-in features include a signal-to-noise measurement, which indicates how much noise, variation, and ac […]

Current Digital Issue

A frequency you can count on There are few constants in life, but what few there are might include death, taxes, and a U.S. grid frequency that doesn’t vary by more than ±0.5 Hz. However, the certainty of the grid frequency is coming into question, thanks to the rising percentage of renewable energy sources that…
