Test sequencing is an analyzer function that allows you to automate repetitive tasks. You can
create a sequence as you are making a measurement. Then when you want to make that same
measurement again, you can recall the sequence and the analyzer will repeat the previous
keystrokes.
The following is a list of some of the key test sequencing features available on the
HP 8753E network analyzer:
n
Limited decision-making functions increase the versatility of the test sequences you create by
allowing you to jump from one sequence to another.
. . . . . . .
A function that allows you to call other sequences as sub-routines.
. .
n
You can create, title, save, and execute up to six sequences.
n
You can save your sequences to a disk using the internal disk drive.
n
You can use the parallel port as a general purpose input/output (GPIO) bus to read five
input bits in a decision making function, and send eight output bits to control a
peripheral.
Note
Product note 8753-3 “RF Component Measurements Applications of the
Test Sequence Function” provides practical applications examples for test
sequencing. This note was written for the HP but also applies to the
HP 8753E.
