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'

Asyncio connections

The AsyncInstrument class can be used for usage with asyncio:

from asyncio import get_event_loop
from vxi11 import vxi11


instr = vxi11.AsyncInstrument("sqs-ilh-las-osz_dpo71254c")


async def acquire():
    await instr.open()
    print(await instr.ask("*IDN?"))
    # In our case, prints 'TEKTRONIX,DPO71254C,C500158,CF:91.1CT FV:10.5.1 Build 24'

    cmd = "DAT:SOU " + ",".join(f"CH{x}" for x in range(1, 5))
    await instr.write(cmd)

    await instr.write("WAVFRMS?")

    readout = await instr.read_raw(-1)
    print(readout)

    await instr.close()


loop = get_event_loop()
loop.run_until_complete(acquire())
