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 supply could simulate the AC line […]

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.
What hardware accessories can you attach to a USB oscilloscope?
A wide range of hardware accessories are available for USB oscilloscopes. This FAQ reviews a few of the more popular options including a variety of probes plus wireless synchronization of multiple USB oscilloscopes and chassis that can combine and synchronize USB oscilloscopes with other instruments like arbitrary waveform generators and multimeters. Probes and more probes […]
What are the important specifications of USB oscilloscopes: Part 1?
USB oscilloscopes are compact and low-cost. If properly specified, they can be highly capable instruments. This FAQ reviews some important USB oscilloscope specifications including the number of channels, sample rate, bandwidth, refresh rate, and memory depth. Part 2 of this series considers specifications (available Sept. 8) for triggering, input ranges and probes, zooming, and control […]
12-bit oscilloscope reaches 65 GHz, tests high-speed links
The WaveMaster 8000HD series from Teledyne LeCroy goes where no 12-bit oscilloscope has gone before. Serial digital data streams never stop reaching for higher data rates. Buses such as PCIe Gen 6 (64 Gtransfers/sec) and USB4 V2 (80 Gb/sec) have gone to PAM4 and PAM3 modulation, respectively, to reach their current data rates. Two-level modulation […]
What specialist software is available for USB oscilloscopes: Part 2?
This FAQ looks at software that can synchronize multiple oscilloscopes, perform mathematical functions, and transform a basic USB oscilloscope into multiple instruments. A USB oscilloscope consists of signal capture and conditioning electronics, a personal computer (PC) that can be a laptop, tablet, or desktop, plus PC software. The availability of application specialist software is a […]
What specialist software is available for USB oscilloscopes: Part 1?
USB oscilloscopes capture analog and digital signals. Through software, engineers can analyze protocols and logic signals. By adding a D/A converter, a USB oscilloscope can also become a waveform generator. A USB oscilloscope consists of the signal capture and conditioning electronics package, a personal computer (PC) that can be a laptop or tablet unit, or […]
What’s a USB oscilloscope?
By connecting to a computer, a USB oscilloscope lets engineers offload screens and compute-intensive functions to the host, which reduces needed bench space and brings portability. Oscilloscopes are sometimes grouped into three types, benchtop, portable, and USB. The first two types are self-contained, but USB oscilloscopes are not. They consist of the electronics that capture […]
What is PCIe gen 6 and how do I test it? Part 2
PAM4 modulation boosts throughput but adds test challenges. Part 1 of this two-part series described the evolution of the PCI Express (PCIe) standard, including the move from non-return-to-zero (NRZ) signaling in PCIe 5 to four-level pulse-amplitude modulation (PAM4) signaling in PCIe 6. What unique test challenges does PCIe 6 present? As mentioned in Part 1, […]
Expand your RF test equipment’s range to 20 GHz
Extend the frequency of RF test equipment from 6 GHz to 20 GHz. RF systems such as satellite, Wi-Fi, UWB, and radar often need to bring modulated signals up to carrier frequency before transmitting and after receiving. TMYTEK, maker of BBox has introduced its UD Module (UDM) up/down converter, which operates from 6 GHz to […]
