62 Agilent N8211A/N8212A Performance Upconverter Synthetic Instrument Module, 250 kHz to 20 / 40 GHz
3 Programming Examples
Sockets on Windows
In Windows, the routines send() and recv() must be used, since fread() and fwrite() may not
work on sockets. The following steps outline the process for running the interactive
program in the Microsoft Visual C++ 6.0 environment:
1 Rename the lanio.c to lanio.cpp and getopt.c to getopt.cpp and add them to the Source
folder of the Visual C++ project.
The int main() function in the lanio.cpp file will allow commands to be sent to the
N8211A/N8212A in a line-by-line format; the user types in SCPI commands. The int
main1(0) function can be used to output a sequence of commands in a “program format.”
See “Programming Using main1() Function" on page 62.
2 Click Rebuild All from Build menu. Then Click Execute Lanio.exe. The Debug window
will appear with a prompt “Press any key to continue.” This indicates that the program
has compiled and can be used to send commands to the N8211A/N8212A.
3 Click Start, click Programs, then click Command Prompt. The command prompt window
will appear.
4 At the command prompt, cd to the directory containing the lanio.exe file and then to the
Debug folder. For example C:\SocketIO\Lanio\Debug.
5 After you cd to the directory where the lanio.exe file is located, type in the following
command at the command prompt: lanio xxxxx “*IDN?”. For example:
C:\SocketIO\Lanio\Debug>lanio xxxxx “*IDN?” where the xxxxx is the
hostname of your N8211A/N8212A. Use this format to output SCPI commands to the
N8211A/N8212A in a line by line format from the command prompt.
6 Ty p e exit at the command prompt to quit the program.
Programming Using main1() Function
The int main1() function will output a sequence of commands in a program format. If
you want to run a program using a sequence of commands then perform the following:
1 Enter the hostname of your N8211A/N8212A in the openSocket function of the
main1() function of the lanio.cpp program.
2 Rename the lanio.cpp int main1() function to int main() and the original int
main() function to int main1().
3 Select Rebuild All from Build menu. Then select Execute Lanio.exe.
The program will run and display results similar to those shown in Figure 5.
