Wst 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:

nLimited decision-making functions increase the versatility of the test sequences you create by

allowing you to jump from one sequence to another.

,,.:; :., ...:,.:,.

.... /

 

 

w A T#&SUI$ ;~~~~~~~~~

function that allows you to call other sequences as sub-routines.

 

.:.c: ;:.:.:...: . . ..A

 

nYou can create, title, save, and execute up to six sequences.

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

nYou 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.

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 8753B but also applies to the HP 8753E.

Features That Operate Differently When Executed In a Sequence

The analyzer does not aRow you to use the following keys in a sequence:

Commands That Sequencing Completes Before the Next Sequence Command

B&U3

The analyzer completes all operations related to the following commands before continuing with another sequence command:

nsingle sweep

nnumber of groups

nauto scale

w marker search

nmarker function

ndata + memory

nrecall or save (internal or external)

ncopy list values and operating parameters
