GPIB Controller
Sets the GPIB port into controller or device mode. In the normal state, GPIB controller is disabled,
which allows the analyzer to be controlled by a remote computer. When GPIB Controller is enabled, the
instrument can run software applications that use the instrument's computer as a GPIB controller;
controlling devices connected to the instrument's GPIB port.
When GPIB Controller is enabled, the analyzer application itself cannot be
NOTE
controlled over GPIB. In this case it can easily be controlled via LAN or USB. The
GPIB port cannot be a controller and device at the same time. Only one controller
can be active on the GPIB bus at any given time. If the analyzer is the controller,
an external PC cannot be a controller.
To control the instrument from the software that is performing GPIB controller operation, you can use an
internal TCP/IP connection to the analyzer application. Use the address TCPIP0:localhost:inst0:INSTR
to send SCPI commands to the analyzer application.
