Sequencing
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 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.
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
Sequence Function” provides practical applications examples for test
sequencing. This note was written for the HP but also applies to the

In-Depth Sequencing Information
That Operate Differently When Executed In a Sequence
The analyzer does not allow you to use the following keys in a sequence:
Commands That Sequencing Completes Before the Next Sequence
The analyzer completes all operations related to the following commands before continuing
with another sequence command:
sweep
n
number of groups
n
auto scale
marker search
n
marker function
n
data memory
n
recall or save (internal or external)
n
copy list values and operating parameters
n
Walt 0*
*Wait 0 is the special sequencing function with a zero entered for the delay value.
