Sequencing
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:

Limited decision-making functions increase the versatility of the test sequences you create by
allowing you to jump from one sequence to another.

You can save your sequences to a disk using the internal disk drive.

You can use the parallel port as a general purpose input/output (GPIO) bus to read five
‘ITL
input bits in a decision making function, and send eight ITL output bits to control a
peripheral.
