A method of testing a DUT via a wireless signal medium to enable the final function test of a device to be tested (DUT) which is a fully assembled radio frequency (RF) data packet signal transceiver without requiring a wired signal connection. A wireless (OTA) test signal that is ...
If the test results are still displayed in the unit of MB/s, multiply the value by 8 to obtain the actual Wi-Fi speed in the unit of Mbit/s. The theoretical Wi-Fi speed is the smaller value between the downlink speed and the wireless link speed. For example, if the downlink speed ...

Generating an RF carrier signal requires an RF signal generator that provides frequency stability and low phase noise and is free of other spurious noises. Learn how to set up an RF signal generator for a carrier signal and optimize the noise settings.
In this application note, Copper Mountain Technologies presents a simple and practical “do-it-yourself” cable test procedure, along with test results derived from the procedure. The results shown correspond to a 50 Ohm 26” N-type male to SMA male FleXus cable, using one of CMT...
While OTA RF measurements have some unique challenges, there are several things you can do to maximize success...
we have been able to access Test RF environment app through an iphone 8 via this URL in the cell phone browser: https://my301892.s4hana.ondemand.com/sap/bc/gui/sap/its/ewm_mobgui?~transaction=/scwm/rfui&sap-langu... We have now acquired the Zebra device. Do we need something in...
A 50Ω dummy load is a simple but crucial piece of test equipment. Not to perform tests on its own, but to provide a good testing environment. A common test is output power of a transmitter, or a stage within a transmitter. At QRP power levels of 5 watts or less, it becomes very...
The next transformation in cellular networks, 5G Advanced, will bring higher bandwidth, lower latency and higher energy efficiency to applications like enhanced mobile broadband, massive IoT and edge computing. While these are big benefits for mobile network operators, it is causing RF and component ...
As with any program on Unix systems, you need to set the executable bit for a shell script file, but you must also set the read bit in order for the shell to read the file. The easiest way to do this is as follows: 与Unix 系统上的任何程序一样,您需要为 shell 脚本文件设置可执行位...
