Advanced triggering techniques can help you track down elusive problems. In part 1 of this series, we investigated the fundamentals of the oscilloscope trigger function, including the simple edge trigger that originated with analog oscilloscopes. In this part, we look at additional triggers that help with troubleshooting. What are some other types of triggering? Advanced […]

Review: Tekbox TBCG4 harmonic comb generator
The Tekbox TBCG4 harmonic comb generator produces a wide range of known frequencies for EMC immunity testing and routine checking of EMC chambers. I’ve used harmonic comb generators for decades in various applications, including antenna measurements, cable resonance measurements, and shielding-effectiveness testing. I also find them useful for checking the daily consistency of test chambers […]
How to calculate and apply an inverse FFT: part 1
The inverse Fourier transform (inverse FFT or iFFT) reverses the operation of the Fourier transform and derives a time-domain representation from a frequency-domain dataset. In early 2024, EE World published a series on the Fourier transform, which can convert a time-domain signal to the frequency domain (Figure 1, red arrow). The process is reversible (Figure […]
Flea market vintage test equipment, September 2024
The monthly “Flea at MIT” featured an abundance of test equipment. We even bought some.
14-bit oscilloscope delivers low noise, fast updates
Keysight’s InfiniiVision HD3 series oscilloscopes let you see signals with 4x the resolution of 12-bit instruments.
Four-channel USB oscilloscopes sample at 5 GS/sec
The PicoScope 3000E series has models with analog bandwidths of 350 MHz and 500 MHz. Hitting the “sweet spot” for analog bandwidth, the 3000E Series — 500 MHz (3418E) and 350 MHz (3417E) — USB oscilloscopes from Pico Technology fill a gap in the company’s oscilloscope offerings in terms of bandwidth. Both models feature four […]
Screenless oscilloscope fits 2U rack space
The MXO 5C screenless oscilloscope from Rohde & Schwarz comes in four or eight channels with 2 GHz bandwidth.
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 […]
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 4 Series B 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 […]
