name: PTF
full_form: Power Transfer Function
context: This method measures the EIRP in an anechoic chamber with the separation between the manufacturer declared coordinate system reference point of the BS and the phase centre of the receiving antenna of no less than 2D2/Î», where D is the largest dimension of the antenna of BS and Î» is the wavelength. The measurement system setup is as depicted in figure 7.2.1-1 for TX requirements, and in figure 7.2.1-2 for RX requirements.

description: The Power Transfer Function (PTF) is a measurement used to quantify the power transfer between the reference transmitter (REF TX) and receiver (RX) in various test equipment setups. It is an essential parameter in characterizing the performance of devices, such as those capable of directly extracting the PTF like a Vector Network Analyzer (VNA), or separate transmitter and receiver test equipment configurations.
explanation: The context describes PTF as a measurement used to assess power transfer between components in a system. It is used to characterize device performance, making it a measurable quantity.
