but it can easily changed from the front panel. GPIB Controller is made up of a computer with GPIB
I/O interface hardware and an operating system which is compatible with IEEE-488 standard.
The GPIB controller sends ASCII command strings on GPIB to control GPIB instrument on GPIB bus.
For Example, a simple carrier frequency command "FR 100MZ" can be sent to the GPIB Bus by the
controller. If the installation is done correctly, the frequency display will change to 100MHz.
4.3. Operating instructions
