Question

我正在尝试使用python控制一个乐器。在代码期间，我需要一次又一次地重新发出相同的命令以从仪器中读取数据。当我使用命令一次我得到答案，但我有它在for循环我得到消息“ERR”的数据。我不知道如何解决这个问题，任何人都可以帮助我吗？下面是我的代码及其输出：

import visa

rm = visa.ResourceManager()
print(rm.list_resources())
my_instrument = rm.open_resource('TCPIP0::169.254.164.61::3602::SOCKET', read_termination='\r\n')
for i in range(0, 10):
    my_instrument.ask('RMMEAS\r')
    ry3 = my_instrument.read()
    print(ry3)

输出

C:\ProgramData\Anaconda3\python.exe C:/Users/nishant.mittal/PycharmProjects/demo.py/kjbkn.py
('TCPIP0::192.168.001.020::3602::INSTR', 'ASRL3::INSTR', 'ASRL4::INSTR', 'ASRL10::INSTR')
8,0.022,0.027,0.029,0.042,0.056,

Process finished with exit code 0

Answer 1

我从来没有尝试过这样的东西，但我猜是因为它打印出来

traceback

我认为它有效，因为退出代码0意味着它正确编译（根据C和C ++），而不是你想要的方式。我也认为这是正确的，因为它不会打印出>>> while True print('Hello world') File "<stdin>", line 1 while True print('Hello world') ^ SyntaxError: invalid syntax错误。

这是Python中的一个错误：

老实说，我不知道如何帮助你...对不起...... :(

我希望我对此有所帮助！
