Abstract

The invention relates to a vector signal source plug-in card-type structural module based on a PCI extension for instrumentation (PXI) bus, which comprises a PXI interface circuit 1, a baseband signal generating circuit 2, a digital-to-analogue conversion circuit 3, a frequency synthesis circuit 4, an in-phase quadrature (IQ) vector modulation circuit 5 and an adaptive logic circuit (ALC) control and vector signal source output circuit 6 which are combined with an external plug-in card E to form a modular structural integrity. According to the software radio technology and the modular structural design principle of an integrated circuit, a mathematical model is established; a microwave and a high-speed digital processing chip are adopted to set required vector signal source frequency, amplitude and power to perform real-time calculation to generate modulation output. Technologically, the optimal shielding, grounding, decoupling, filtering and leakage prevention optimization design is adopted to realize the characteristics of reasonable layout, compact structure, skillful installation, wide expansibility, high adaptability, high reliability and the like, and the requirements of automatic testing and analysis of a traditional digital communication system are completely met, and the need of the development of the communication technology is adapted.

Description

Technical field [0001] The invention relates to a signal source module, in particular to a PXI bus-based vector signal source plug-in card structure module. Background technique [0002] Since the advent of PXI bus technology, automatic test systems based on PXI bus have been extensively developed. PXI bus vector signal source also appeared and obtained a large number of applications. There is no such product in China. Foreign countries mainly consist of the PXI-5670 vector signal generator of NI Company and the PXI3020 RF signal generator of Aeroflex Company. [0003] According to the description on the NI official website, NI PXI-5670 is a modular 2.7GHz RF vector signal generator, its power and flexibility can meet the needs of product development from design to manufacturing. NI PXI-5670 can generate arbitrary waveforms with true 16-bit resolution with 100MS / s speed, 512MB memory and 20MHz real-time bandwidth. PXI-5670 can generate custom and standard modulation formats, i...
