你好,所以我猜你的问题是你运行64位操作系统?
如果是,我们还没有支持33220A的64位应用程序的IVI驱动程序。 幸运的是,你实际上并不需要使用IVI驱动程序,你可以只发送SCPI(64位工作),根据我的经验,无论如何在Matlab中更直接,这是一个关于如何在Matlab中发送arbs的33220A示例 使用SCPI:%{AsciiArb是一个示例程序,演示如何将任意波形下载到仪器易失性存储器中并使用以下配置进行回放:此arb生成8192点脉冲波形,其中前400个点定义为正 脉冲从0伏到最大定义电压幅度。 波形:Arb幅度:2伏峰峰值偏移:0伏输出阻抗:50欧姆输出:启用此示例适用于Agilent 33210A,33220A和33250A%}%清除所有变量,关闭所有打开的文件全部清除; 关闭所有; CLC; %打开并创建签证会话,以便与函数生成器fgen = visa('AGILENT','TCPIP0 :: 156.140.92.62 :: inst0 :: INSTR')进行通信; set(fgen,'OutputBufferSize',100000); 的fopen(FGEN); %Query Idendity字符串和报告fprintf(fgen,'* IDN?'); idn = fscanf(fgen); fprintf(idn)fprintf(' n n')%清除并重置仪器fprintf(fgen,'* RST'); fprintf(fgen,'* CLS'); %使用8192点0-1数据创建arb波形fprintf('生成波形... n n')rise = []; 对于i = 1:1:10%设定上升时间(10分)* / z =(i-1)/ 10; y = num2str(z); s1 = sprintf(',%s',y); 上升= [上升s1]; 结束宽度= []; for i = 11:1:411%设定脉冲宽度(400点)* / y = num2str(1); s2 = sprintf(',%s',y); width = [width s2]; end fall = []; 对于i = 412:1:422%设定下降时间(10分)* / z =(422-i)/ 10; y = num2str(z); s3 = sprintf(',%s',y); 跌倒= [跌倒s3]; 结束低= []; for i = 423:1:8192%将剩余点设置为零* / y = num2str(0); s4 = sprintf(',%s',y); 低= [低s4]; end%组合所有字符串s = [上升宽度下降低]; %将数据串与scpi命令组合使用arbstring = sprintf('DATA VOLATILE%s',s); %Send命令设置所需的配置fprintf('下载波形... n n')fprintf(fgen,arbstring); %make instrument等待数据下载,然后转到下一个%命令set fprintf(fgen,'* WAI'); fprintf('下载完成 n n')%设置所需的配置。 fprintf(fgen,'VOLT 2'); %将最大波形幅度设置为2 Vpp fprintf(fgen,'VOLT:OFFSET 0'); %将偏移设置为0 V fprintf(fgen,'OUTPUT:LOAD 50'); %将输出负载设置为50欧姆fprintf(fgen,'FREQ 1000'); %设定频率为1KHz fprintf(fgen,'FUNC:USER VOLATILE'); fprintf(fgen,'FUNC:SHAP USER'); %启用输出fprintf(fgen,'OUTPUT ON'); %打开通道1输出%读取错误fprintf(fgen,'SYST:ERR?'); errorstr = fscanf(fgen); %错误检查strncmp(errorstr,'+ 0,“无错误”',13)errorcheck ='生成的任意波形没有任何错误 n'; fprintf(错误检查)else errorcheck = ['错误报告:',errorstr]; fprintf(错误检查)end%用函数发生器fclose(fgen)关闭签证会话; 以上来自于谷歌翻译 以下为原文 Hello, So I'm guessing the issue is that your running a 64 bit OS? If yes we don't have an IVI driver that supports 64 bit applications for the 33220A yet. Luckily, you don't actually need to use the IVI driver, you can just send SCPI instead (works on 64 bit), which in my experience is more straighforward in Matlab anyway, Here is a 33220A sample on how to send arbs in Matlab using SCPI: %{ AsciiArb is a sample program that demonstrates how to download an arbitrary waveform into instrument volatile memory and play back the same with the configuration below: This arb generates a 8192 point pulse waveform, of which the first 400 points define a positive pulse from 0 volts to the maximum defined voltage amplitude.
