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 […]
RF signal generators cover 10 MHz to 18 GHz range
The Boonton SGX1000 RF Signal Generators are a new series of instruments that combine high performance RF signal generation capabilities with an intuitive user interface. They cover a frequency range from 10 MHz to 18 GHz to provide superior operational performance such as extremely fast frequency switching, phase noise figures as low as -123 dBc/Hz […]
Kit verifies isolation effectiveness of RF shielded enclosures
The JRE TVK Isolation Tester can help verify the proper shielding isolation of RF enclosure test set-ups. This test combination, consisting of the STA-1, a sensitive handheld spectrum analyzer, and the HPSS-1, a high power 2.45-GHz test signal source, can easily and quickly measure enclosure isolation down to less than -100 dB. The TVK Isolation […]
Detecting counterfeit integrated circuits without a microscope
Curve-trace testing can reveal whether an incoming batch of ICs are bogus without resorting to destructive inspection measures. Alan Lowne | Saelig Making fake “lookalike” integrated circuits which resemble real ones takes minimal skill. It may simply require finding cheap parts in the same package and applying new markings. This problem has arisen due to […]
Two/four-channel 100-350 MHz scopes feature 200-Mpt memory, 10-in touch-screen, external mouse/keyboard control, 50-MHz waveform generator
The new Siglent SDS2000X Plus Digital Oscilloscope Series consists of four models: one two-channel 100-MHz bandwidth (software upgradeable to 350 MHz) and three four-channel models (100/200/350 MHz.) The 350-MHz models can be upgraded to 500 MHz on two independent channels. A large 10.1-in capacitive touch-screen supports multi-touch gestures. The oscilloscope range also offers a 10-bit […]
Infrared cameras for PCB development and diagnosis
Infrared cameras can help size up the surface temperatures of electronic components, PCBs, and other objects to reveal unseen problems. ALAN J. LOWNE, SAELIG CO. INC. Thermal imagers, also called infrared cameras, capture a 2-D representation of objects in front of their germanium optics (ordinary optical glass impedes IR wavelengths). They present a visible version […]
Real-Time 27-GHz spectrum analyzers are PC controlled
Saelig Company, Inc. announces the availability of the compact RTSA7550 Real-Time Spectrum Analyzer – a powerful, full-featured spectrum analyzer designed to analyze wireless signals in real-time (not progressively scanned). This is essential for seeing intermittent and frequency-varying signals. The Model RTSA7550 has all the standard features of a conventional spectrum analyzer such as frequency controls, […]
