Description of Interface Functions
Note: The description of the UNIX format is only relevant to instruments with Windows NT controller.
RSDLLibfind()
The function provides a handle for access to the device with the name udName.
VB format: Function RSDLLibfind (ByVal udName$, ibsta%, iberr%, ibcntl&)
As Integer
C-format: short FAR PASCAL RSDLLibfind( char far *udName, short far
*ibsta, short far *iberr, unsigned long far *ibcntl)
C format (Unix): short RSDLLibfind( char *udName, short *ibsta, short *iberr,
unsigned long *ibcntl)
Parameter: udName IP address of device
Example: ud = RSDLLibfind ("89.10.38.97", ibsta, iberr, ibcntl)
The function must be called before all other interface functions.
The function supplies a handle as a return value. The handle must be specified in all functions for
accessing the instrument. If no instrument with the name udName is found, the handle will take on a
negative value.
The local link on the instrument is established with the name ’@local’. For setting up a link via a
network, on the other hand, the IP address of the instrument must be given (eg ’89.1.1.200’).
RSDLLibwrt
The function sends data to the instrument with the handle ud.
VB format: Function RSDLLibwrt (ByVal ud%, ByVal Wrt$, ibsta%, iberr%,
ibcntl&) As Integer
C format: short FAR PASCAL RSDLLibwrt( short ud, char far *Wrt, short
far *ibsta, short far *iberr, unsigned long far *ibcntl )
C format (Unix): short RSDLLibwrt( short ud, char *Wrt, short *ibsta, short
*iberr, unsigned long *ibcntl )
Parameter: ud Device handle
Wrt String sent to the device.
Example: RSDLLibwrt(ud, "SENS:FREQ:STAR?", ibsta, iberr, ibcntl)
The function allows setting and query commands to be sent to the measuring instruments. The function
RSDLLibeot() is used for defining whether the data are interpreted as a complete command.
