How Do I Prevent Blow-By in a Conducted Throughput Measurement?

By |2019-04-24T19:14:04+00:00June 30th, 2016|Design Innovation|

In an engineering laboratory, certain Radio Frequency (RF) measurements such as data throughput (radio sensitivity) is commonly made by direct connection via coaxial cable with an adjustable attenuator in line. This enables the technician to simulate a range in free space for the purpose of measuring or validating sensitivity. Attenuation between the radios would [...]

How Do I Make a Simple Notch Filter for Lab Use?

By |2019-04-22T16:44:03+00:00March 19th, 2016|Design Innovation, RF Filters|

Virtually all disciplines apply certain inherited tricks-of-the-trade to expedite tasks. RF engineers and technicians are no different from anyone else…in that respect at least. Oftentimes there is a need for a quick and easy-to-build simple notch filter to improve laboratory measurements. For instance, an RF signal generator’s second harmonic can negatively impact measurements taken of the [...]
