Conducted RF Power and Sensitivity Measurement

In this video I perform LTE measurements with a wireless callbox (R&S CMW500) in a conducted RF setup. This means that the radio signals are measured inside the RF cable and do not propagate in air. Why is this test important? Because it can be a very costly mistake to show up at the RF chamber with a modem that does not work. Additionally, transmit power can vary between production units. Very often it's in your interests to know which modems have the highest transmit power and which ones have the lowest.
