Digitizers Application Examples

	This section contains example programs that demonstrate some E1563A or
	E1564A Digitizer applications. The examples list only the SCPI commands
	required to perform the application. You can use these examples to help you
	develop programs for your specific application
Introduction	Example programs are provided on the VXIplug&play media that have been
	compiled and tested using Microsoft® Visual C++™ Version 1.51 for the
	C programs. All C language example programs are written for the 82341
	GPIB Interface Card using the Agilent VISA I/O Library.
Programming	All projects written in C programming language require the following
Requirements	Microsoft® Visual C++™ Version 1.51 settings to work properly:
	• Project Type: QuickWin application (.EXE)
	• Project Files: <source code file name>.C
	[drive:]\VXIPNP\WIN\LIB\MSC\VISA.LIB (Microsoft® compiler)
	[drive:]\VXIPNP\WIN\LIB\BC\VISA.LIB (Borland® compiler)
	• Memory Model: Options Project Compiler Memory Model Þ
	Large
	• Directory Paths: Options Directories
	Include File Paths: [drive:]\VXIPNP\WIN\INCLUDE
	Library File Paths: [drive:]\VXIPNP\WIN\LIB\MSC (Microsoft®)
	[drive:]\VXIPNP\WIN\LIB\BC (Borland®)
	• Example programs: On the Universal Instrument Drivers CD.
NOTE
NOTE	You can find instructions to compile C language programs for a PC in the
	Agilent VISA User’s Guide. See the section "Compiling and Linking a
	VISA Program".
Hardware Used
Hardware Used	PC running Windows with an 82341 GPIB interface. The VXI modules are
	installed in a VXI C-Size mainframe. An E1406A Command Module is the
	resource manager and is connected to the PC via an 82341 GPIB card.
