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.
Spike, our spectrum analyzer software, offers the ability to make these 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).
Check out our lead software developer walking through the process of making these power measurements, with Spike, on YouTube:
The video dives into a bit of theory on measuring channel power, and shows exactly what these measurements look like in Spike. The video uses examples involving WLAN and Pulsed WLAN waveforms, utilizing both real-time and Zero Span measurement methods.
