Controlling the Test Set and Making Measurements
Commands
Commands
These three methods of control and their commands are detailed below
and on the following pages.
Computer Control
The first method of controlling the test set is to write GPIB (HP-IB)
commands to the network analyzer, which then writes the command to
the test set by way of the parallel port. The following examples use the
variable D, which is defined in Table 5-1 on page 5-6.
To use a parallel port connection with the Agilent 8753D,E, use an
GPIB (HP-IB) command to write bits on the parallel port. The following
example assumes that the address of the network analyzer is 16.
NOTE Be sure to use the ending semicolon.
The second method of controlling the test set is to address the Agilent
87050A Option H15 test set directly over GPIB (HP-IB), using a
controller to write directly to the test set's GPIB (HP-IB) port. See
Figure 5-1 on page 5-4 for a diagram of connections for this type of
control. The following example assumes that the address of the test set
is 12.
