A network analyzer formula editor and its data graphic display method and device

Abstract

The invention provides a network analyzer formula editor and a data graphic display method and device thereof. The network analyzer formula editor comprises a formula editor module and a data processing and graphic displaying unit. The formula editor module comprises a built-in parameter, function and operator unit, a custom parameter and function enter unit, a formula editor expression enter unit, an intelligent expression correcting and information reminding unit and an expression calculating unit which are connected and communicate with each others. The data processing and graphic displaying unit comprises data format selection, formatted data sets, offset and proportion, memory display and interface display and refresh. The network analyzer formula editor has the advantages that the technical problem that expressions which are entered by a user and which directly contains complex constant (such as S21 / (1S11) + (13I)) cannot be calculated is solved; by the aid of the formula editor program module, the technical problem that a user cannot enter custom parameters is solved, and the user is allowed to customize parameters.

Description

technical field [0001] The invention belongs to the technical field of a network analyzer formula editor and its data graphic display, and in particular relates to a network analyzer formula editor and its data graphic display method and device. Background technique [0002] A network analyzer is an instrument used to measure the characteristics of radio frequency, microwave and millimeter wave networks. It calculates and quantifies the network parameters of the network under test by applying appropriate excitation signals to the network under test and receiving and processing the response signals of the network. The network analyzer provides a variety of calibration methods such as single-port, response isolation, and full dual-port. It is equipped with various data display formats such as logarithmic amplitude, Smith chart, and polar coordinates. The track described in this article refers to a series of measured data points. The setting of the track will affect the mathema...

AI Technical Summary

Problems solved by technology

[0005] 1 The formula editing of the existing network analyzer adopts the method of equation to edit, and the constant data of the equation expression cannot be directly entered as a part of the expression, such as inputting S21 / (1-S11)+(1+ 3i) is not computable, such that simultaneous intuitive mathematical changes to the magnitude and phase of the measured trace are not possible

[0006] 2. The existing network analyzer equation editor module requires that the parameters input by the expression must be the measurement parameters built into the program itself, and cannot be user-defined data parameters

And there is no import interface for parameters, which cannot meet some special needs of users

[0007] 3. In the existing network analyzer equation editor module, when the user enters a formula that cannot be calculated, the equation editor module can only prompt whether the formula can be calculated, and cannot intelligently point out the location and type of the error, nor can it give a specific The error prompt information must be corrected and corrected by the user himself

[0008] 4. When drawing in real time with high efficiency, the graphics refresh will be relatively slow, or the graphics will flicker when the graphics refresh is too fast
