The ability to make channel power measurements and adjacent channel power (ACP) measurements are a crucial requirement of any qualified RF test bench. These measurements display the signal energy leaked into adjacent communications channels and the range of frequencies that contain the modulated communication signal power – all very important when working with communication standards such as Wi-Fi, Bluetooth, and cellular technologies.
Our Spike software offers the ability to make channel power measurements and ACP measurements when using Signal Hound test equipment for RF analysis – all through an easy-to-use point-and-click interface that runs on your Windows or Linux PC (in fact, if you want to see what Spike looks like, you can download and run it for free).
Our lead software developer recently walked through the process of making channel power and ACP measurements with Spike on video, and we posted it on YouTube:
The video dives into a bit of theory on how channel power is measured, and shows exactly what these measurements look like in Spike. Examples involving WLAN and Pulsed WLAN waveforms are used, utilizing both real-time and Zero Span measurement methods.
