3. BAPI FUNCTIONS
This chapter describes the Application Programming Interface for Board Instrument (hereafter shortened to
BAPI) functions that are used in Advantest's R3755x/R3760 internal PCI board network analyzers and are
required to generate measurement applications by using Visual Basic 6.0 and Visual Basic 2008.
3.1.
Communication Protocol
To use the R3755x/R3760, the server program which controls the R3755x/R3760 must be executed in advance.
Controlling the R3755x/R3760 from a user application program can be achieved by using the BAPI functions
to communicate with the server program.
Winsock (socket communications utilizing the TCP/IP protocol) is used to communicate between the user
application program and the R3755x/R3760 server program.
, shown below, shows the communication process between the R3755x/R3760 and the User appli-
cation.
