Hi, I am trying to write a Gaussian pulse generated in Python to a keysight 33600A waveform generator. The pulse appears fine in Python, but when I attempt to use write_binary_values(message = 'SOUR2:DATA:ARB:DAC RABI, ', values = pulse,...
write_binary_values for large amount of data (more than 46'699 bytes) immediatly fail with VI_ERROR_TMO. What bothered me with this particular issue was that no matter the timeout that I set on my device, I would always immediately get t...
write_binary_values()方法:向仪器发送二进制数据。例如:instrument.write_binary_values(b'\x01\x02\x03') read_binary_values()方法:从仪器接收二进制数据。例如:response = instrument.read_binary_values(3) lock()方法:锁定仪器,防止其他程序访问。例如:instrument.lock() unlock()方法:解锁仪器,允许其他程序...
# 假设需要读取的数据类型为单精度浮点数('f'),且为小端格式 data = instrument.query_binary_values('MEAS:CURR?', datatype='f', is_big_endian=False) print(data) 断开与仪器的连接: 完成数据读取后,应关闭与仪器的连接以释放资源。 python # 关闭仪器连接 instrument.close() 综上所述,使用PyVISA...

data = self.conn.query_binary_values(':READ:WAV0?', datatype='f', is_big_endian=True) It has been used many many times before without fail. Would the above syntax need to be parsed differently in the newer version of PyVISA? I am still using PyVISA Documentation, Release 1.9.dev0...
