Handheld microwave spectrum analyzers feature resistive touchscreens
The SAF Tehnika Spectrum Compact SG Series RF Signal Generators are hand-held and easy-to-use RF signal generators for the 6 GHz – 40 GHz licensed microwave frequency bands. There are four models in the SG range, covering specific frequency ranges: 6 GHz-12 GHz (J0SSAG11), 10 GHz-18 GHz (J0SSAG12), 17 GHz-24 GHz (J0SSAG13) and 24 GHz-40 […]
The challenge of testing obsolete PCBs
How to test and maintain obsolete systems when the relevant documentation is absent. Alan Lowne, Saelig Co. Inc. Obsolete PCBs or boards lacking circuit schematic diagrams present a conundrum when there’s a need for repair. Online searches for old datasheets may not be productive. What happens when obsolete boards must be fixed but there is […]
Faraday bags sized to handle cellphones up to rack-mounted gear
Disklabs Shielding Enclosures are available in sizes ranging from cellphone covers to instrument rack shields, for shielding mobile phones, tablet devices, laptops, and other electronic devices from all RF signals. Common features of these Faraday shields include military-grade, water-resistant soft-sided enclosures, and greater than 90 dB signal attenuation of ambient wireless signals such as cellphone […]
Mini 15-GHz signal generator fits in your pocket
The Windfreak SynthHD Mini is a software tunable RF signal source that generates signals from 10 MHz to 15 GHz with a 0.01-Hz resolution and an output power of up to 20 dBm. The generator also supports FM, AM, pulse, sweep, and list modulations. It can be programmed for standalone operation, running without any PC […]
Active-probe PC-based scopes feature up to 5 GSa/sec real-time sampling, 4-GSa-deep memory
New 750-MHz and 1-GHz models have been added to the four-channel PicoScope 6000E Series, which provide 8 to 12 bits of vertical resolution, and up to 5GSa/sec sampling rate with a 4-GSa memory, allowing these scopes to display single-shot pulses with up to 200 psec time resolution. The four new four-channel models added to the […]
