Transmitting/receiving switching control signal generation and device supporting multi-T/R assembly test

Abstract

The invention discloses a transmitting / receiving switching control signal generation method and device supporting multi-T / R-assembly test. The device comprises a T / R assembly state controller. The T / R assembly state controller is connected with a plurality of digital T / R assemblies to be tested. The T / R assembly state controller is connected to a digital oscilloscope through a transmitting / receiving switching line. The plurality of digital T / R assemblies to be tested are connected to the digital oscilloscope through a switching network. The T / R assembly state controller comprises a transmitting / receiving switching unit. The transmitting / receiving switching unit is used for sending a synchronization signal to the digital oscilloscope while the state of each digital T / R assembly to be tested changes. The method and device can realize multi-assembly transmitting / receiving switching time test through only one transmitting / receiving switching control signal output port; and transmitting / receiving switching control signal output can be strictly synchronous with the change of transmitting / receiving state of each assembly.

Description

technical field [0001] The invention relates to a method and a device for generating a transceiver switching control signal supporting multi-T / R component testing. Background technique [0002] T / R components are the most numerous and most important type of microwave multifunctional components in phased array electronic equipment. It is based on a time-sharing working system. In the transmitting state, the power of the transmitting excitation signal is amplified, distributed through the network and fed back to the antenna element, and phase weighted to form a good transmission pattern; in the receiving state, the signal from the antenna element is Weak small signals are amplified without distortion and low noise, and amplitude and phase weighting are also performed to form a good receiving pattern. The transceiver switching time is an important index to evaluate the performance of T / R components, which characterizes the time required for the transition from transmission to ...
