R&S AFQ100A
The programming examples for remote control are all written in Microsoft
the VISA functions require the declaration of the functions and constants prior to their use in the project.
This can be accomplished either by adding the modules VISA32.BAS and VPPTYPE.BAS or a
reference to the VISA32.DLL to the project.
The modules visa32.bas and vpptype.bas can be found in the <VXIpnpPath>\WinNT\include (typically
C:\VXIpnp\WinNt\include).
Note:
Manual control is designed for maximum possible operating convenience. In contrast, the priority of
remote control is the predictability of the device status. Therefore, control programs should always
define an initial device status (e.g. by the command *RST) and then implement the required settings.
Drivers for the generator, e.g. IVI-COM and LabVIEW drivers, are available in the download area of
the R&S product website (http://www.rohde-schwarz.com/product/AFQ100).
