Python Vxi11 Examples

Opening a connection

Connect to an Agilent MSO7104A oscilloscope on IP address 192.168.1.104:

>>> import vxi11
>>> instr =  vxi11.Instrument("192.168.1.104")
>>> print(instr.ask("*IDN?"))
'AGILENT TECHNOLOGIES,MSO7104A,MY********,06.16.0001'

Connect to an Agilent E3649A via an HP 2050A GPIB bridge:

>>> import vxi11
>>> instr = vxi11.Instrument("192.168.1.105", "gpib,5")
>>> print(instr.ask("*IDN?"))
'Agilent Technologies,E3649A,0,1.4-5.0-1.0'

Configuring connections

Open a connection and set the timeout:

>>> import vxi11
>>> instr = vxi11.Instrument("192.168.1.104")
>>> instr.timeout = 60*1000
>>> print(instr.ask("*TST?"))
'0'
