Linux Programming Example
This section illustrates how to program and control the spectrum analyzer to realize the common functions
in Linux operating system.
Programming Preparations
1. Programming environment:
Operating system: Fedroa 8 (Linux-2.6.23)
GCC version: gcc-4.1.2
2. Install the VISA library. First, check whether your PC has installed NI's VISA library. If not, download it
from NI website (
http://www.ni.com/visa/). The installation procedures are as follows:
Download the VISA library NI-VISA-4.4.0.ISO from the NI website.
Create a new directory.
#mkdir NI_VISA
Mount the isofile
#mount -o loop -t iso9660 NI-VISA-4.4.0.iso NI_VISA
Enter the NI_VISA directory to install
#cd NI_VISA
#./INSTALL
Unmount the isofile
#umount NI_VISA
After the installation is finished, the default installation path is /usr/local.
3. Build communication between the spectrum analyzer and the PC. Use the network cable to connect the
analyzer to the PC via the LAN interface on the rear panel of the analyzer. You can also use a network
cable to connect the spectrum analyzer to the local area network where the PC resides.
After the spectrum analyzer is connected to the PC properly, configure the network address for the
spectrum analyzer to make its address to be within the same network segment where the PC resides.
For example, if the network address and DNS setting configured for the PC are as shown in the figures
