Hello, I have a LeCroy Waverunner 6050A oscilloscope and I want to use it as a data acquisition hardware. I want to use a PXIe-8108 with a RT operating system to access the LeCroy oscilloscope using VISA through a LAN. I can see the oscilloscope in MAX [3] and I can communicate to it using IO resource: "VICP::169.254.103.3" from the My Computer "169.254.103.1", but not from the NI-PXIe8108 controller "169.254.103.2". [1] The simple vi [2] works when it is running on My Computer, but not from NI-PXIe8108. It returns the error: Error -1073807343 occurred at VISA Open in LeCroy_hello.vi Possible reason(s): VISA: (Hex 0xBFFF0011) Insufficient location information or the device or resource is not present in the system. I checked that the LeCroy can ping both My Computer and PXIe8108. In MAX, I can add the oscilloscope under both "My Sysyem" and "NI-PXIe8108". The PXIe8108 is using the: NI Real-Time PharLap 13.1 Operating system Firmware Revision: 13.1 The LeCroy is set to use TCIP (VICP) for remote connections and its firmware version is 6.5.0.5. Do I need to install some softwares (like the Teledyne LeCroy VICP Passpor) on the PXIe8108 and if yes how do I do it? Thanks and cheers, John. [1] project.png [2] hello_lecroy_vi.png [3] MAX.png

Hello John, I have not worked with RT stuff in quite some time, so I am not sure how to install it. You do need the VICP Pa$$port though. The alternative is to use the LXI(VXI-11) interface type on the scope. With this interface, you can use a straight TCPIP VISA resource. i.e. TCPIP0::169.254.103.3::inst0::INSTR This interface is slower than the VICP interface when transferring large sets of data. The VICP Pa$$port is just a dll (two dll's on my 64 bit OS, but the 64 bit version is for 64 bit LabVIEW) that is can be found on the PC at: C:\VXIPnp\WinNT\bin Cheers, Leonard Brown Applciations Engineer TeledyneLeCroy

Solved!

The problem was with the asynchronous and synchronous I/O settings on the VISA read/write sub-VI. Changing the setting to synchronous solved the problem.

Cheers,

John
