Troubleshooting DL7400 USB Communication Error Using LabVIEW

When communicating or controlling the DL7400 via USB in LabVIEW, you must use the USB driver files provided by NI-VISA (Version 3.0 or later). The Yokogawa USB driver files labeled YKUSB or YKMUSB can be used when LabVIEW is not used to communicate with the instrument.

In case both driver files are installed, you will need to update to driver file in Windows Device Manager. Please refer to the attached document file for the procedures for updating the USB driver file. ​

Mixed Signal Oscilloscopes

A mixed signal oscilloscope is an instrument enabling the simultaneous, time correlated observations and analysis of analog with digital (logic) signals, to establish causal relationships between the various areas of a device's electronics. They are purpose-built tools for troubleshooting electrical anomalies, measuring parametric values, and monitoring cause and effect relationships between signals.

Oscilloscopes

Capture, analyze, and troubleshoot electrical or real-world physical signals. Oscilloscopes observe the change of electrical signals over time, continuously graphed on a display as voltage or amplitude vs. time.
