Basic tools such as DMMs and oscilloscopes may be the only test gear needed for small printed circuit board repairs, but it pays to know when automated systems would be a better choice. Alan Lowne | Saelig Co. Inc. PCBs are more complicated to repair today than even a few years ago. Manufacturing mistakes and […]
PCB testing apparatus equipped with repositionable fine-point spring-loaded probes
The Sensepeek PCBite System is a professional-yet-affordable PCB testing apparatus with a system of repositionable fine-point spring-loaded probes, a large (8.3×11.7-in) metal baseplate, and four magnetic-base PCB holders for clamping circuit boards in a stable, fixed position. The probes are attached to a flexible, stable gooseneck arm that has a powerful magnetic base, and the […]
Economical digital microscope includes built-in LCD for standalone PCB inspection
The Saelig SAE106S Digital Microscope is a versatile tool designed specifically for PCB inspection, but can also prove to be useful in many other fields such as coin or mechanical part examination. The SAE106S may be used as a standalone inspection device for circuit board examination using its built-in 4.3-in LCD screen or it may […]
Programmable dc loads offer advanced performance options
The new Siglent SDL1000X/X-E Series Programmable dc Loads can be set to simulate a wide range of load qualities. Four models offer two different resolutions and two power capacity choices with an input range of 150 V/30 A. The SDL1020X/SDL1020X-E versions are 200-W models, while the SDL1030X/SDL1030X-E versions have a 300-W capability. The ‘X’ versions […]
Portable power quality analyzer decodes three-phase power problems
The Hioki PQ3198 Power Quality Analyzer can be used for assessing power usage as well as for investigating power supply problems such as voltage drops, flicker, harmonics, and other electrical issues. Hioki portable power analyzers can measure single to three-phase lines with a high degree of precision and accuracy. New features include the ability to […]
Economical real-time spectrum analyzer monitors wireless signals in real time
The compact ThinkRF R5x50 Real-Time Spectrum Analyzer series are designed to monitor wireless signals in real-time rather than via progressive scan as with most common spectrum analyzers. Real-time analysis is essential for observing intermittent or frequency-hopped signals. Sleeker, lighter weight, and quieter than their predecessor models, the R5550 and R5750 analyzers offer improved spectral performance, […]
PC-based scope blends 5 GHz bandwidth and equivalent-time sampling
The PicoScope 9404-05 5GHz oscilloscope is a PC-based high-resolution device which brings an affordable high-speed performance by combining the benefits of real-time and equivalent-time sampling with high analog bandwidth. The PicoScope 9404-05 has four 5 GHz 50-Ω input channels, each with its own advanced 12-bit ADC, which provide the required timing and display resolution for […]
Clamp meters handle ac currents up to 2,000 A
The Hioki CM4141 and CM4142 AC Clamp Meters are rated for use with currents up to 2,000 A. These new current sensors feature a compact, sturdy jaw design for easy application around existing wiring, robust enough to push and pull wiring. The CM4141 and CM4142 deliver accurate results even when measuring ac current waveforms that […]
Rugged real-time spectrum analyzer/RF recorder works up to 20 GHz
The Spectran XFR V5 PRO Real-Time Spectrum Analyzer is a portable, rugged RF detection device designed to capture even the briefest signal transmissions. Its rapid signal acquisition scans a 20-GHz bandwidth in less than 20 msec, making it the world´s fastest counter-surveillance receiver. The instrument’s internal GPS also indicates the precise location of the measured […]
Low-cost spectrum analyzers monitor in real-time to see intermittent and frequency-hopped signals
The compact ThinkRF R5500 Real-Time Spectrum Analyzer series is designed to monitor and analyze wireless signals in real-time and not progressively scanned like most common spectrum analyzers. Real-time analysis is vital for being able to observe intermittent or frequency-hopped signals. The R5500 series comes in three models to cover 8, 18, or 27-GHz signals. They […]
