The Control Program
The Control program demonstrates the control of the Agilent
87050A Option H15 by GPIB (HP-IB) commands or the parallel port.
This program can be used to select any port combination manually
(listed on the following pages). This program will first ask the user
which method will be used to control the Agilent 87050A Option H15,
either GPIB (HP-IB) or parallel port. It will then ask which ports are to
be enabled. The port entries are done in pairs (reflection/transmission)
with the two numbers separated by a comma. The numbers may range
from 0 through 16 for the test ports. For example, an entry of 2,5 will
connect the Reflection port to Port 2 and the Transmission port to Port
5. The program is a continuous loop. Press STOP to end program
execution.
