If you’re looking for a portable oscilloscope for field troubleshooting or for demonstrations, look at the Micsig TO series. Here’s my take on the four-channel 300 MHz variant, TO3004. The Micsig TO3004 oscilloscope (Figure 1) is an 8-bit, four-channel, tablet-sized portable oscilloscope that’s also available with 100 MHz and 200 MHz varieties with two or […]

Review: PCBite circuit board holder and probe kit
The PCBite kit holds your circuit board in place while you probe it, reducing the risk of short circuits. Recently, I’ve had to test and characterize many small PC boards, including embedded processors, DC-DC converters, and other wireless-related products, for EMC issues. I’ve never really had an easy way to keep these boards from moving […]
Isolated current probes eliminate ground loops
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 […]
RF-isolated current probe achieves 140 dB CMRR at DC
Tektronix has released two new power measurement devices: the TICP Series IsoVu isolated current probes and the EA-PSB 20000 Triple series power supply. The TICP Series probes utilize RF isolation technology for current measurements across voltage systems. The probes achieve 140 dB common-mode rejection ratio (CMRR) at DC and up to 90 dB at 1 […]
APEC 2024: Test equipment
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 […]
High-impedance, high-bandwidth oscilloscope probe captures serial bus signals
The Infiniimax 4 active probe from Keysight reaches 52 GHz, enough to see signals on PCIe 6/7, 800 Gb/sec Ethernet, DDR 5/6, and other high-speed serial buses. Oscilloscopes with 100 GHz and higher bandwidths can display signals on 224 Gb/sec PAM4 serial buses and they’ve been available for several years. Without probes of high enough […]
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 […]
Water-cooled probe injects disturbances onto power rails
The P2124 from Picotest let’s you inject modulation signals onto your board’s power rails for noise immunity testing.
USB Type-C test coupon fixtures speed scope debug tasks
New USB Type-C High-speed and Sideband Test Coupon Fixtures provide the industry’s first oscilloscope solution for high-speed probing and analysis of an active data link at the USB Type-C connector. Additional connection to a Teledyne LeCroy protocol analyzer provides complete debug capability of any USB Type-C link negotiation failure. USB Type-C devices undergo negotiation when […]
MIPI M-PHY High-Speed GEAR 5 UFS 4.0 protocol analyzer/exerciser sports solder-in probes
The Eclipse M52 Analyzer/Exerciser supports the next generation of M-PHY High Speed Gear 5 (HS-G5), UniPro 2.0/UFS 4.0 development and can be configured now with the new GEAR 5 solder-in probes. The Eclipse M52 analyzer/exerciser assists design and test engineers working with the high data rates and aggressive power management of the UniPro and UFS […]
