Abstract

The invention provides a multifunctional ground station verification signal source. The signal source comprises a programmable frame generator, a serial-parallel conversion module, a baseband modulation module, an up converter, a power detection module, a serial port communication module and a chargeable cell. Baseband modulation and primary upconversion single-chip technologies are integrated in the system, and compared with verification via separate components, the integrity is improved, and verification data is more accurate; a central frequency controller, a frequency offset controller and a gain adjusting module are arranged so that the field environment is simulated, RF output power can change according to specified waveform and period, the control precision reaches 1dB, frequency and power of an RF output center can change according to specified waveform and period, the minimal resolution can reach 1 Hz, and the detection precision is higher; and the signal source can be used in the field due to arrangement of the rechargeable cell.

Description

technical field [0001] The invention belongs to the technical field of telemetry ground stations, in particular to a multifunctional ground station verification signal source. Background technique [0002] The telemetry ground station is the eyes of aircraft such as bullets / arrows / aircraft / satellites. It is the main tool for monitoring and judging whether the relevant parameters of the aircraft are working normally. Therefore, the performance indicators of the telemetry ground station are particularly important. [0003] The main method of conventional telemetry ground stations is laboratory measurement. The laboratory test conditions are actually the most ideal conditions, and it is impossible to simulate the use environment. It often shows that the indicators in the laboratory test are up to standard and the functions are complete. The bit rate is high or the work is intermittent. The existing ground station calibration signal sources have the problems of low detection ac...
