The new SP145 14.5 GHz spectrum analyzer is available for pre-order now!→

We recently announced a new noise figure analysis mode in our Spike RF analysis software. This new analysis mode has already been a big hit with many of our users, but for those that aren’t quite sure why making noise figure measurements is a big deal (or how to perform the measurement), we created a couple content items to help with the learning process.

Something to watch

For those who prefer to watch a process, Signal Hound programmer Roger Rush – developer of the noise figure analysis mode – sat down in front of the camera to walk through the process of making a basic noise figure measurement. The video explains why noise figure measurements are important, walks through an example hardware configuration, and then proceeds to demonstrate the making of a noise figure measurement. Head on over to YouTube to watch the video, or check it out here:

Something to read

If you’d like to read and learn about noise figure measurements, then download our new Noise Figure Analysis Feature Overview PDF. The document talks about the why/how of noise figure measurements, includes a bunch of details on the math behind the measurement (the Y-Factor Method, specifically), and then provides a walk-through on performing the measurement.

The walk-through process requires Spike v 3.5.12, an SM or BB-series spectrum analyzer, a noise source, and a device to test. Even if you don’t have the ability to re-create the walk-through, understanding the concept of a noise figure measurement and the why/how is reason enough is to warrant a quick read, if you’re so inclined.
