Embodiment Construction

[0023] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0024] The present invention proposes a multi-card calibration method, such as figure 1 As shown, the calibration system is set in the host computer, and is divided into the following functional units, including: card number recognition unit, FLASH writing unit, FLASH reading unit, signal generating unit, signal analysis unit, calibration data generating unit, calibration Nine units including control unit, multi-card management unit, calibration initialization unit and calibration initialization unit. figure 2 The calibration hardware configuration of three AMC5814 baseband source modules is given in .

[0025] (1) Card number identification unit

[0026] It is used to read the slot number of each module. There is no slot number constraint in the PXIe bus specification. For this reason, the slot number is read in a custom way. The hardware decodes the f...

Abstract

The invention discloses a multi-card calibration method. According to the method, a calibration system is established to realize multi-card calibration, so that the process of respectively preheating during each calibration is avoided. The method is capable of enabling a plurality of same modules of a same case to share a same (DLL) dynamic link library, completing appointed module calibration, improving the calibration efficiency, sharing the preheating time and overcoming the defect that the calibration of each module of the same case is long in consumed time.

Description

technical field [0001] The invention belongs to the field of synthetic instruments, in particular to a multi-card calibration method. Background technique [0002] Modern warfare requires weapons and equipment to be intelligent, informatized, and comprehensive. Therefore, broadband, small size, and multi-function will become the focus of weapon equipment development. In order to achieve the above requirements, a large amount of data calibration is an indispensable link. How Realizing the calibration of a large amount of data and how to save calibration time, especially the calibration of multiple identical modules in the same chassis, is a very important part of the development process of weapons and equipment. The warm-up time is an indispensable part of RF module calibration. Its time is It is relatively long, and a lot of warm-up waiting time will be wasted during multi-card calibration. Contents of the invention [0003] Aiming at the above-mentioned low-efficiency si...
