Abstract

The invention provides a T / R component testing device and a method for checking the safety of the device. The device introduces a single-pole double-throw switch to physically separate the transmitting output channel from the receiving input channel, and an attenuator or a coupler is built into the transmitting In the output channel, this will not affect the noise figure of the receiving channel and the test of the standing wave ratio of the input port due to the large insertion loss of the channel. Compared with the existing test device, the test efficiency is improved, the influence of repeated wiring on the test accuracy and repeatability is reduced, and the number of test accessories such as attenuators or couplers is reduced, and the construction cost of the device is reduced. The integration of the device is facilitated. The safety verification of the T / R component test device before use is to query the connection state of the switch through the switch status register to ensure that the connection position of each switch is correct, and then use the low-power low-frequency excitation signal to verify the connectivity of the device to ensure When the switch fails, the test instrument will not be burned, which improves the safety of the device.

Description

Technical field [0001] The invention relates to the field of T / R component testing, in particular to a T / R component testing device and a device safety verification method. Background technique [0002] The T / R component mainly includes three parts: transmitting channel, receiving channel, and driving control. In addition, there are component interface parts such as radio frequency input and output, low-frequency connector. The transmitting channel mainly completes the amplification of the RF excitation signal and outputs it to the feeder network; the receiving channel amplifies the echo signal received by the antenna and ensures a low noise figure; the module's transceiver switch and phase and attenuation are controlled by the drive control part carry out. [0003] T / R components have the characteristics of multiple channels, coexistence of large and small power, and port multiplexing, and there are many types of indicators that require multiple test instruments to complete the t...
