Making Measurements
Using Test Sequencing
NOTE Presetting the instrument does not run the Auto Sequence automatically.
Gosub Sequence Command
The softkey, located in the Sequencing menu, activates a feature
that allows the sequence to branch off to another sequence, then return to the original
sequence. For example, you could perform an amplifier measurement in the following
manner:
1. Create sequence 1 for the specific purpose of performing the gain measurement and
printing the results. This sequence will act as a sub-routine.
2. Create sequence 2 to set up a series of different input power levels for the amplifier gain
measurements. In-between each power level setting, call sequence 1 as a sub-routine by
pressing . Now, sequence 2 will print the
measurement results for each input power level applied to the amplifier.
NOTE The softkey branches the sequence to another
sequence in a particular location (SEQ1 through SEQ6), not to a given file
name.
The GPIO Mode
The instrument’s parallel port can be used in two different modes. By pressi ng and
then toggling the softkey, you can select either the mode or the
mode.
The GPIO mode switches 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 the analyzer can interact with through test sequencing.
TESTSET I/O
The TESTSET I/O interconnect on the rear panel was originally intended for use solely
with the HP/Agilent 85046A/B and HP/Agilent 85047B external S-parameter test sets.
Since the introduction of the 8753D, a network analyzer with an internal test set, this test
set I/O port has become a general purpose control port for a variety of external devices,
such as the K36 or K39 test adapters and Option 014 configurations. Refer Table 1-5 on
page 1-111 for the definition of each pin of the test set I/O connector.
CAUTION +22 volts is available on the TESTSET I/O connector. Be careful not to
connect this to a printer port or to sensitive electronic equipment.
This connector, with the limit output, TTL OUT and TESTSET I/O outputs can also be
used with part handlers to provide control interface.
