How do I Capture External Signals that are not NI Product-Driven on the GPIB Bus?Hardware: GPIB>>Plug-in Controllers>>PCI-GPIB+
Problem: How do I Capture External Signals that are not NI product-driven on the GPIB Bus? Solution: Some applications that are not necessarily driven by an NI driver or product require monitoring a GPIB bus. As an example, a user might want to monitor the communication between two GPIB devices, neither of which use NI software. Some would think that NI-Spy would be the correct solution, but it is not the case. NI-Spy can only "spy" on data that is driven by NI drivers on a computer. In order to do monitor the signals on the GPIB bus, one must use the GPIB Analyzer, which is available with the PCI-GPIB+. The standard PCI-GPIB does not have the GPIB analyzer functionality. In the above case of monitoring communication between an instrument and the controller, one would piggy-back a GPIB cable from another computer equipped with the PCI-GPIB+ card. Then, monitoring the passing data is possible using the GPIB Analyzer utility that is included with the NI-488.2 driver. Related Links: NI 488.2 - GPIB Analyzer Users Manual Attachments:
