2. Required Software

Some software components need to be installed before using this instrument driver. The minimum versions of these components are listed below, and can be downloaded from the Download Site.

VISA 3.3 or later
LabVIEW 8.0 or later (Not supported on versions 9.0 and greater).


For more details, refer to the LabVIEW Help under Help » VI, Function, & How-To Help.

3. Known Issues

- 9520 series units with optical and AT45 output modules may encounter write errors since the optical and AT45 module queries are not yet parsed correctly. When the channel is configured, the vi may try to set the output levels, which does not apply when an optical module is installed.
