Abstract

The present invention proposes a synchronization method for intra-pulse data acquisition of a pulse network analyzer. Data pre-acquisition is performed before the test, and the arrival time of the pulse is calculated, compared with the pulse synchronization signal to obtain a deviation value, and then the data acquisition delay is corrected. . The method of the present invention can automatically judge the arrival time of the pulse, and automatically correct the data collection time; in the pulse synchronization test, the measurement position within the pulse can be accurately set, and the required data can be accurately obtained; the data processing method is simple, and the calculation amount is comparative Small, it will not have a significant impact on the test speed; the use of narrow-band filtering can eliminate noise interference, and it can still detect accurately when the signal is small, with high sensitivity.

Description

technical field

[0001] The invention relates to the technical field of testing, in particular to a synchronization method for intra-pulse data acquisition of a pulse network analyzer. Background technique

[0002] The pulse network analyzer is an instrument that obtains the characteristic parameters of the device under test by generating a pulse excitation signal, exciting the device under test and receiving its scattered signal. Its main structure is as follows: figure 1 shown.

[0003] The pulse network analyzer generates a radio frequency continuous wave signal through a radio frequency signal source, and at the same time, a pulse generator generates a pulse signal with a certain frequency and duty cycle. The pulse signal modulates the radio frequency continuous wave into a pulse modulation signal through the modulator, and the pulse modulation signal is injected into the device under test to scatter, and the scattered signal is received by the network analyzer, and beco...

Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] The pulse network analyzer can pulse-modulate the excitation signal, and the excitation signal is received by the receiver of the network analyzer after being scattered by the device under test, and is used to extract information such as amplitude and phase. In the synchronous pulse test mode, the digital receiver is required to collect data on the signal when the pulse arrives, and the pulse signal has to pass through the DUT, the cable and the test cha...
