Programming
Typical
Measurements
In This Subsection
Using the Example
Programs
This subsection illustrates how the general SCPI concepts presented
in previous subsections apply to programming real measurements.
To introduce you to programming with SCPI, we must list the
commands for the swept CW generator. We will begin with a
simplified example.
The example programs are interactive. They require active
participation by the operator. If you desire to get an understanding
of the principles without following all of the instructions, read the
“Program Comments” paragraphs to follow the programmed activity.
The HP-IB select code is assumed to be preset to 7. All example
programs in this section expect the swept CW generator’s HP-IB
address to be decimal 19.
To find the present HP-IB address, use the front panel.
Press SYSTEM (MENU).
Select
HP-D
Menu
A&s
Menu My Adrs .
The active entry area indicates the present decimal address. If the
number displayed is not 19, reset it to 19.
Press
(iJ
@
(ENTER). If the swept CW generator does not respond
to a front panel address change, set the HP-IB address switch (rear
panel) to 31 (all ones) enabling front panel changes to both address
and interface language.
Now check that the interface language is set to SCPI.
Press
(PRIOR).
An asterisk denotes the selected interface language. If an asterisk is
not next to the SCPI key label, select Power Up Language SCPI .
