我最近从吉时利仪器公司购买了一台SMU 2450，但我试图将MATLAB SCPI代码从2400转换为2450，当我试图做一个简单的循环触发时出现错误，任何人都可以告诉我出了什么问题在我的代码中
% Model 2400 Specific Functions
% Sweep current and measure back voltage
fopen(obj1)
fprintf(obj1,':*RST')
% setup the 2400 to generate an SRQ on buffer full
fprintf(obj1,':*ESE 0')
fprintf(obj1,':*CLS')
fprintf(obj1,':STAT:MEAS:ENAB 512')
fprintf(obj1,':*SRE 1')
% buffer set up
fprintf(obj1,':TRAC:CLE')
fprintf(obj1,':TRAC:POIN 10') % buffer size

This is the 2450 code

非常感谢任何帮助
