RIGOL编程使用

RIGOL示波器可由多种语言编程进行操作。

这里仅仅给出RIGOL编程手册给出的MATLAB的例程，以及自己写的程序。并提供读取的波形数据的工作区（1000Hz，5V有效值），可在无示波器下进行测试。

RIGOL MATLAB 例程

编程手册例程
源代码

% 创建 VISA 对象。'ni'为销售商参数，可以为 agilent、NI 或 tek，
% 'USB0::0x1AB1::0x04B0::DS2A0000000000::INSTR'为设备的资源描述符。创建后需设置设备的属性，
% 本例中设置输入缓存的长度为 2048
% MSO2000A = visa( 'ni','USB0::0x1AB1::0x04B0::DS2A0000000000::INSTR' );

MSO2000A.InputBufferSize = 2048;
N = MSO2000A.InputBufferSize;
%打开已创建的 VISA 对象
fopen(MSO2000A);
%读取波形
fprintf(MSO2000A, ':wav:data?' );
%请求数据
[data,len]= fread(MSO2000A,N);

% ------------------自加部分------------------

% 获取周期
fprintf(MSO2000A,':MEASure:PERiod? <CHANnel1>');
T = fscanf(MSO2000A);
T = str2num(T);
F = 1/T             % 计算频率

% 获取采样频率
fprintf(MSO2000A,':ACQuire:SRATe?');
Fs = fscanf(MSO2000A);
Fs = str2num(Fs)
% 计算采样总时间
Tmax = N/Fs

% ------------------自加部分------------------

%关闭设备

% 数据处理。读取的波形数据含有 TMC 头，长度为 11 个字节，其中前 2 个字节分别为 TMC 头标志符

自写带GUI界面的MATLAB程序
源代码
% GUI里不能带clear，会清空GUI的工作变量
% 我的一个猜想，采样点数为2048是固定的，但采样得到的波形不一样，即所测信号的频率不一样。
function varargout = gaopinGUI(varargin)
% GAOPINGUI MATLAB code for gaopinGUI.fig
%      GAOPINGUI, by itself, creates a new GAOPINGUI or raises the existing
%      singleton*.
%
%      H = GAOPINGUI returns the handle to a new GAOPINGUI or the handle to
%      the existing singleton*.
%
%      GAOPINGUI('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in GAOPINGUI.M with the given input arguments.
%
%      GAOPINGUI('Property','Value',...) creates a new GAOPINGUI or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before gaopinGUI_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to gaopinGUI_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
