Priced at only $80, the portable RF Meter is a low-cost signal-strength measurement tool for designers of RF radio systems. Two models are available to detect signals ...

Multiple high sensitivity sensors installed for detecting Power line, Smart meter, Cell phone, Microwave etc. Identify/recognize the common possible sources, such as Power line, Cell Tower, Microwave, ...

[Scott] wrote in to us with his simple, but well done RF signal strength meter. As he points out in his post, sometimes an Arduino is overkill, so a Picaxe 08M was used instead. Apparently this was a ...

The output power of an RF or microwave system is a key determinant of its performance. For this reason, signal power is measured at every stage – from design and prototyping to maintenance in the ...

Morgan Hill, Calif.—Anritsu Company introduces the MS2711D Spectrum Master, a handheld spectrum analyzer that delivers greatly improved sweep speed, and is designed with a built-in pre-amp that ...

Wireless communications products that depend on RF principles are everywhere these days, and the growth rate is astonishing. From cell phones and wireless PDAs to Wi-Fi-enabled laptops, Bluetooth ...

The author is senior technologist at NPR Labs in Washington. Field strength measurements are almost as old as radio itself, as engineers have endeavored to test and improve their RF transmission ...

The National Semiconductor LMV225 is a linear RF power meter IC in an SMD package. It can be used over the frequency range of 450 MHz to 2000 MHz and requires only four external components. The input ...

The author is a broadcast contract engineer who has a unique way of measuring the carrier frequency of the AM stations in his care. Making off-air frequency measurements of AM broadcast stations can ...
