Problems solved by technology

[0004] To sum up, the PXIe bus vector signal real-time transceiver module adopts the superheterodyne method for down-conversion during signal analysis, which requires a multi-stage frequency conversion method and an additional zero-frequency suppression circuit. The circuit design is complicated, the volume is large, the number of slots is large, and the power High consumption and high cost, unable to meet the needs of building a miniaturized automatic test system; at the same time, the function is relatively simple, without vector network analysis function, unable to perform network parameter testing, and unable to meet the requirements of multi-functional parameters

Abstract

The disclosure provides a PXIe bus vector signal real-time transceiver module device and method, including a signal frequency conversion receiving unit, a signal direct up-conversion unit and a digital processing unit, and a signal frequency conversion receiving unit configured to directly input the radio frequency signal input from the first port After amplification and attenuation conditioning, the frequency is directly down-converted to a zero-IF signal, and transmitted to the digital processing unit; the digital processing unit is configured to generate two orthogonal digital baseband signals through pseudo-random sequence generation and interpolation filtering, and the generated orthogonal two-way Baseband signal, outputting two orthogonal analog baseband signals to the direct up-conversion unit; the signal direct up-conversion unit is configured to directly up-convert the baseband orthogonal two-way signal to a radio frequency signal and then output from the second port; the signal frequency conversion receiving unit The dual-port test function is realized through the multi-level routing switching coupling mode between the direct up-conversion unit and the signal.

Description

technical field [0001] The disclosure belongs to the technical field of vector signal processing, and in particular relates to a PXIe bus vector signal real-time transceiver module device and method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] According to the inventor's understanding, when the traditional PXIe bus vector signal real-time transceiver module signal occurs, it adopts the direct up-conversion mode of quadrature modulation, and the digital processing unit generates baseband I and Q baseband signals through pseudo-random sequence generation and interpolation filtering, etc., and then IQ The two-way signals are directly up-converted by the signal direct up-conversion unit and the local oscillator signal of the local oscillator synthesis circuit, and finally output after conditioning such as filtering and amplification.
