Wireless Keyboard and Mouse Testing Made Easy
应用文章
Most of the wireless mice and keyboards work in the ISM 2.4 GHz band, and most of them employ either Bluetooth® technology or the FSK modulation format for signal transmission. These wireless computer peripherals must transmit signals with enough power for the receiver to easily capture the signals. The wireless mice and keyboards must also avoid creating electromagnetic interference and disrupting other radio communications using the same frequency.
As this brief illustrates, a variety of equipments are used to create a test system capable of ensuring that wireless computer devices meet the defined standards. One of the key components in such a configuration is a spectrum analyzer, such as the Keysight N9321C BSA spectrum analyzer.
