Using Getting Started VI with HP54845 scope

[Maelstrom2]

I'm trying to run the supplied "Getting Started" IVI with the Agilent HP54845 scope that is included in the download package for the hp548xx device. The instrument input is GPIB::7::INSTR and the Initialize with Options portion of the subVI returns an OK when run. The series of VIs in the subVI "hp548xx Acq Wfm Edge Triggered" also return OK values up to the "Read Wfm" VI. I then get a timeout error (Error number BFFF0015). Am I using the wrong instrument handle and, if so, what is the correct handle. This is the default format when I create an input to this "Read Wfm" VI. The Plug & Play VIs work for this device and I am able to display scope traces in LabView when I use the supplied P&P VIs so I am able to talk to t
he device.

Probably the most common reason for timeout (BFFF0015) in an oscilloscope read waveform is failed trigger event. Most likely the Getting Started VI uses edge triggering. Check the edge trigger level setting and verify that it is set to be within the range of your expected signal.
