The Parallel Port Input Connector
This input is connected to the network analyzer. The analyzer provides
control signals that drive the switches inside the test set. In
pass-through mode, it also accepts signals required to drive a printer.
The Parallel Port Output Connector
The output from this connector is used either to control another test set,
or to control a printer, depending upon how the Printer/Test Set switch
is set.
The Printer/Test Set Switch
This switch determines the function of the Parallel Port Output
connector. When switched to Printer, the Parallel Port Output will pass
through printer driver signals. When switched to Test Set, an
additional test set can be controlled from the Parallel Port Output
connector.
GPIB Connector
This connector allows the test set to be connected directly to a
controller. See Figure 3-3 on page 3-12.
