Test equipment is everywhere. Every trade show has it regardless of the focus. Power is no exception. At APEC 2024, EE World visited several booths displaying test equipment: meters, oscilloscopes, source-measure units (SMUs), bench power supplies, and electronic loads. The photos and videos below highlight what we saw, presented in alphabetical order by company. In […]
Digital Oscilloscope
Digital oscilloscopes offer up to 2GSa/s sampling rate, 56Mpts memory depth
Uni-Trend US has introduced the UPO1000 Series digital oscilloscopes, which come in 50MHz, 100MHz, and 200MHz bandwidth options. The oscilloscopes feature a 4-channel design and use Fast Acquire Phosphor™ technology. The UPO1000 series has a real-time sampling rate of up to 2GSa/s and a maximum memory depth of 56Mpts. It also features a 500,000 waveforms […]
Product tryout: Tektronix 4 Series B oscilloscope
EE World gets its hands dirty on the latest Tektronix oscilloscope. So many features, so little time. When Tektronix gave the press a preview of the 4 Series B 12-bit mixed-signal oscilloscope and TekScope software, I asked to try the software. Days later, the real thing arrived in a transit case. Fortunately and unfortunately, today’s […]
How to test the automotive SENT protocol
Oscilloscopes and dedicated software can help analyze SENT data. In “What is the automotive SENT protocol?” we looked at the Single Edge Nibble Transmission (SENT) protocol, as defined in accordance with the Society of Automotive Engineers (SAE) J2716 standard. We reviewed the SENT message frame, which includes a synchronization/calibration pulse followed by a status nibble, […]
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 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 […]
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 […]
