PyVISA Timeout error

Question

I am trying to transfer a scope file from Tektronix to PC. Unfortunately I keep getting a TIMEOUT error. My writes work but when reading the raw format I am stuck. Here is my code:

import visa
import time
scope = visa.ResourceManager()
tek = scope.open_resource('GPIB::1::INSTR')
tek.timeout=100000 # timeout 100s
print(tek.query('*IDN?'))
tek.write('FILESYSTEM:FRINT "C:\EDIR\EDIR_812140円mV.png", GPIB')
time.sleep(6)
data = tek.read_raw()
time.sleep(6)
fid = open('C:/Users/svpxi01/Desktop/GPIB read/my_image.png', 'wb')
fid.write(data)
fid.close()
tek.close()
print('Done')

And debug log:

Answer 1

Found my issue.

tek.write('FILESYSTEM:FRINT "C:\EDIR\EDIR_812140円mV.png", GPIB')

is incorrect. It should be

tek.write('FILESYSTEM:FRINT "C:/EDIR/EDIR_812/140mV.png", GPIB')
