Re: labview visa query - NI Communit

NI-VISA is the National Instruments implementation of the industry standard Virtual Instrumentation Software Architecture (VISA) specification. Together, the VISA and VISA .NET specifications define a standard, consistent API for communicating with instruments and other devices in the .NET environment. NI-VISA .NET supports several bus and interface technologies, including TCP/IP, USB, GPIB, Serial, and PCI/PXI. The classes provided by the NI-VISA .NET library implement interfaces. Users who are writing an application for a PCI or PXI card can use NI-VISA to gain full access to all the device's configuration, I/O, and memory-mapped registers. NI-VISA currently supports the PXI interface on Windows, LabVIEW RT (Phar Lap ETS), and Linux. The supported functionality is identical for PCI and PXI cards. The terms PCI and PXI are used somewhat interchangeably in this section; technically, PXI is a rigorously defined extension of PCI Home Community Discussion Forums Most Active Hardware Boards Instrument Control (GPIB, Serial, VISA, IVI) Topic.

For instruments omitting the termination character when transferring binary data, visa library raises a timeout exception in case pyvisa 1.9.0 is used. Note that the behavior is not reverted completely to its pyvisa 1.8 state because for other instruments (for example, Keysight PNA on Ethernet) the termination character is indeed added at the end of the message, and is not counted in the. Note that queuing messages resulting from asynchronous write/read operations is possible in NI Visa (cf. viWriteAsync, viReadAsync functions). However, here the philosophy is different because the whole queries (write/read sequences, including commands) are queued for each device, so that the program does not have to wait until an asynchronous read operation completes before sending other.
