pyvisa/pyvisa-py #130 I have upgraded PyVISA Version: 1.8 to PyVISA Version: 1.9 today. The below binary read syntax from spectrum analyzer seems to fail. data = self.conn.query_binary_values(':READ:WAV0?', data
rawData = self.instance.query_binary_values('waveform:DATA?', datatype = 'B', container = np.array, delay = 0.2) # Query x and y values to scale the data appropriately for plotting xIncrement = float(self.instance.query(':waveform:xIncrement?')) xOrigin = float(self.instance.query('...

K1_Operating_06.pdf), it is not clear in what format the instrument return the value. However as it accept a binary blob of data, I suspect it returns a binary block of data, so using query_ascii_values will not work. Do you know in what format the instrument is supposed to return...
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...
We could add the option to do multiple calls to read_raw in query_binary_values but it would be nice to know that this is really the problem. — Reply to this email directly or view it on GitHubhttps://github.com/hgrecco/pyvisa/issues/118#issuecomment-74115672. ...
Hello guys, I had the same problem with my SPD3303C power supply. To solve this, I put a minimum of 0.1 second delay inside the query or between the write and the read lines: 1) my_power_source.write('*IDN?') time.sleep(0.1) ...
