OpenChoice Desktop is still the easiest path for non-programmers who need quick screenshots and waveform export. For automated test systems, use the same OpenChoice VISA layer but call it from Python, C++, or TestStand.
| Problem | Likely Cause | Solution | | :--- | :--- | :--- | | Instrument not found in OpenChoice Desktop | Missing TekVISA or USB driver conflict | Reinstall TekVISA. On Windows, check Device Manager → Universal Serial Bus devices → “Tektronix Test & Measurement Device”. | | “VISA Error: Timeout” | Wrong resource string or insufficient timeout | Use *IDN? query first. Increase timeout to 5000 ms. | | Corrupted waveform data | Mismatch between DATA:WIDTH and binary encoding | Ensure DATA:WIDTH 1 for 8-bit, DATA:WIDTH 2 for 16-bit. | | LAN connection fails | Firewall blocking VXI-11 port 1024 | Allow Tektronix OpenChoice or port 1024 in Windows Defender Firewall. | openchoice tektronix
