Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

Instrument

✓ import vxi11; instr = vxi11.Instrument('hostname')

✗ from vxi11 import Instrument

Importing Instrument directly from vxi11 fails; you must import the vxi11 module and reference vxi11.Instrument.

Connect to an instrument and query its identity.

import vxi11 instr = vxi11.Instrument('192.168.1.10') print(instr.ask('*IDN?')) instr.close()

Debug

Known issues

gotchaThe constructor 'vxi11.Instrument(host, ...)' does not raise an exception on connection failure immediately; errors may occur on first command.

fix

Wrap the first command in a try block to catch timeouts or connection errors.

affects: all

gotchaTimeout parameter is in milliseconds, not seconds. Default is 10000 (10 seconds).

fix

Pass timeout in milliseconds, e.g., timeout=5000 for 5 seconds.

affects: all

gotchaThe 'ask()' method sends a command and reads response; it does not include a trailing newline. For commands that require termination, use 'write()' explicitly with '\n'.

fix

Use 'instr.write('*IDN?\n')' then 'instr.read()' if needed.

affects: all

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'vxi11'

The library is not installed.

fix

Run 'pip install python-vxi11' and ensure the correct Python environment.

AttributeError: module 'vxi11' has no attribute 'Instrument'

Importing 'Instrument' directly from vxi11 (e.g., 'from vxi11 import Instrument').

fix

Use 'import vxi11' and then reference 'vxi11.Instrument()'.

vxi11.Vxi11Error: VXI-11 connection timeout

Instrument unreachable or wrong IP/hostname, or timeout too short.

fix

Verify network connectivity and increase timeout (milliseconds).
