Method, device and equipment for automatically calibrating AD9361 board card and storage medium

Abstract

The invention relates to the technical field of electronic communication, and discloses a method, a device, equipment and a storage medium for automatically calibrating an AD9361 board card, and the method is characterized in that an available value and / or an available delay value capable of obtaining a correct verification result based on a pseudorandom binary sequence are / is determined through traversal in cooperation with an FPGA technology; and selecting an optimal available value from a plurality of available values and / or a plurality of available delay values to configure a value of 0 * 006 / 7 of an internal register and / or a delay value of an input / output delay unit, so that calibration and adjustment of a receiving path and a transmitting path of the AD9361 board card are automatically completed, and an FPGA program does not need to be independently compiled when the AD9361 board card is produced each time; in addition, manual operation can be greatly reduced, processing troubles are avoided, the RX paths of one or more AD9361 modules on the multiple AD9361 board cards can be rapidly and accurately calibrated, operation of production personnel during later batch production is facilitated, and the production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of electronic communication, and in particular relates to a method, device, equipment and storage medium for automatically calibrating an AD9361 board. Background technique [0002] The AD9361 chip is a high-performance and highly integrated RF agile transceiver launched by ADI for 3G / 4G base station applications. It is packaged in a 10mm×10mm 144-pin chip-scale ball grid array package. The operating frequency of the AD9361 chip is 70MHz-6GHz, covering most licensed and license-free frequency bands, supports tunable channel bandwidth of 200kHz-56MHz, and has a high degree of programmability, so the AD9361 module based on the AD9361 chip (that is, composed of AD9361 chip and its peripheral circuits) are often arranged on the circuit board together with Field Programmable Logic Gate Array FPGA (Field Programmable Gate Array) modules (that is, composed of FPGA chips, several peripheral registers and their perip...

Problems solved by technology

[0006] In order to solve the problems existing in the existing AD9361 board card calibration method that need to independently compile the FPGA program, troublesome processing and unfavorable batch production operation, the purpose of the present invention is to provide a method, device, computer equipment and computer-based automatic calibration of the AD9361 board card. Reading the storage medium can automatically complete the calibration and adjustment of the receiving path and transmitting path of the AD9361 board, which not only eliminates the need to compile the FPGA program independently every time the AD9361 board is produced, but also greatly reduces manual operations and avoids troublesome processing. Quickly and accurately calibrate the RX path and TX path of single or multiple AD9361 modules on multiple AD9361 boards, which will facilitate the operation of production personnel during batch production in the future, greatly improve production efficiency, and facilitate practical application and promotion
