Before diving too deep into the nitty gritty of high frequency probing techniques, it’s imperative to understand a few basics, as described in the remaining portion of this article. The basics include probe calibration and null measurements and a description of the various types of voltage probes available, including their strengths and weaknesses.
RF field probes are specialized measuring instruments with unique specifications and performance characteristics. This article details the main factors to consider in selecting a probe appropriate to your testing needs.
If someone were to ask you what one singular device is most synonymous with testing, or even electrical engineering, the overwhelming response would most likely be the oscilloscope probe.
Usually the confidence you have in your measurements is directly proportional to the cost of your instrument. Take care.
Agilent Technologies Inc. (NYSE: A) today introduced two active differential probes for RF and Microwave instruments -- the U1818A/B -- that feature high differential input impedance from 100 kHz to 7 or 12 GHz... Read More...
