R&S FSMR RSIB Interface Functions
1166.3363.12 4.24-39 E-2
Description of Interface Functions
RSDLLibfind()
The function provides a handle for access to the device with the name
udName
.
VB format:
Function RSDLLibfind (ByVal udName$, ibsta%, iberr%, ibcntl&)
As Integer
C format:
short WINAPI RSDLLibfind( char far *udName, short far *ibsta,
short far *iberr, unsigned long far *ibcntl)
C format (UNIX):
short RSDLLibfind( char *udName, short *ibsta, short *iberr,
unsigned long *ibcntl)
Parameters:
udName
IP address of device
Example:
ud = RSDLLibfind ("89.10.38.97", ibsta, iberr, ibcntl)
The function must be called prior to all other functions of the interface.
As return value, the function provides a handle that must be indicated in all functions for access to the
device. If the device with the name
udName
is not found, the handle has a negative value.
RSDLLibwrt
This function sends data to the device with the handle
ud
.
VB format:
Function RSDLLibwrt (ByVal ud%, ByVal Wrt$, ibsta%, iberr%,
ibcntl&) As Integer
C format:
short WINAPI 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 )
Parameters:
ud
Device handle
Wrt
String sent to the device.
Example:
RSDLLibwrt(ud, "SENS:FREQ:STAR?", ibsta, iberr, ibcntl)
This function allows setting and query commands to be sent to the measuring instruments. Whether the
data is interpreted as a complete command can be set using the function
RSDLLibeot()
.
RSDLLilwrt
This function sends
Cnt
bytes to a device with the handle
ud
.
VB format:
Function RSDLLilwrt (ByVal ud%, ByVal Wrt$, ByVal Cnt&,
ibsta%, iberr%, ibcntl&) As Integer
C format:
short WINAPI RSDLLilwrt( short ud, char far *Wrt,
unsigned long Cnt, short far *ibsta, short far *iberr,
unsigned long far *ibcntl)
C format (UNIX):
short RSDLLilwrt( short ud, char *Wrt, unsigned long Cnt,
short *ibsta, short *iberr, unsigned long *ibcntl)
Parameters:
ud
Device handle
Wrt
String sent to the GPIB parser.
Cnt
Number of bytes sent to the device.
Example:
RSDLLilwrt (ud, '......', 100, ibsta, iberr, ibcntl)
Like
RSDLLibwrt()
this function sends data to a device. The only difference is that binary data can be
sent as well. The length of the data is not determined by a zero-terminated string, but by the indication of
Cnt
bytes. If the data is to be terminated with EOS (0Ah), the EOS byte must be appended to the string.
