Operating Concepts
GPIB Operation
identified by a GPIB address. This decimal-based address code must be different for each instrument on
the bus. This menu lets you set the GPIB address of the analyzer, and enter the addresses of peripheral
devices so that the analyzer can communicate with them. Most of the GPIB addresses are set at the factory
and need not be modified for normal system operation. The standard factory-set addresses for instruments
that may be part of the system are as follows:
The address displayed in this menu for each peripheral device must match the address set on the device
itself. The analyzer does not have a GPIB switch: its address is set only from the front panel. These
addresses are stored in non-volatile memory and are not affected by preset or by cycling the power.
Using the Parallel Port
The instrument's parallel port can be used in two different modes. By pressing Local, and then toggling
the PARALLEL [ ], softkey, you can select either the [COPY], mode or the [GPIO], mode.
The Copy Mode
The copy mode allows the parallel port to be connected to a printer or plotter for the outputting of test
results. To use the parallel port for printing or plotting, you must do the following:
1. Press Local, SET ADDRESSES.
2. Select either PLOTTER PORT, or PRINTER PORT.
3. Select PARALLEL, so that copy is underlined.
The GPIO Mode
The GPIO mode turns the parallel port into a "general purpose input/output" port.
In this mode the port can be connected to test fixtures, power supplies, and other peripheral equipment
that might be used to interact with the analyzer during measurements. This mode is exclusively used in
test sequencing.
