How do I choose an electric motor, and how do I test it? Part 4
You indeed can measure three-phase power in a motor with just two wattmeters. Part 3 of this FAQ concluded with a simplified diagram showing a test setup that included a programmable power supply, a motor under test, a mechanical load, a power analyzer, and host computer. The programmable power … [Read More...] about How do I choose an electric motor, and how do I test it? Part 4
R&S enters eight-channel oscilloscope game
The Rohde & Schwarz MXO 5 series of eight-channel and four-channel oscilloscopes feature fast capture and low-level triggering so you can see signal details. There was a time when we had to live with just two oscilloscope channels. Today, four channels are common but that's not often … [Read More...] about R&S enters eight-channel oscilloscope game

What is the importance of resolution in an oscilloscope?
When looking at the oscilloscope feature of a multi-instrument device or when comparing two benchtop oscilloscopes, the first specifications that we look at are the bandwidth and sample rate. While these are incredibly important specs, often most design work is done well within the limits of most products and the more critical specification to consider is resolution. Did you know that while most […]
