Power Analyzer for Wireless Communication Signals

Jun 29, 2018

Digital modulation methods of mobile and other wireless communications system pose a challenge for producing accurate peak power dimensions. Even though there are lots of diverse implementations, the Orthogonal Frequency Division Multiplexing (OFDM) and Spread Spectrum Modulation would be the most recent technology. Of numerous wireless communication systems, the Power Analyzer connected with 3G such as EVDO (Evolution Data Optimized) or WCDMA (Wideband Code Division Multiple Access) is one that utilizes many modulation schemes. HSPA provides rates of approximately 700-1700kbps for Download and 500-1200 kbps upload. The EVDO station has a bandwidth of 1.25 MHz using the forward connection data speed up to 3.1 Mbps and also the reverse connection information up to 1.8 Mbps. Back in EVDO Rev. A, the forward connection of this system is composed of one data channel that's split into 1.67 ms timeslots. The Power Analyzer suppliers needs to creep up to the complete power while staying within a predetermined power/time profile. A peak power video bandwidth of 1 MHz must guarantee compliance with all the profile.
