Measurements
In This Subsection
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 synthesizer. We will begin with a simplified
example.
Using the 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 synthesizer’s HP-IB address to be
decimal 19.
To find the present HP-IB address use the front panel.
Press SYSYTEM
(MENU).
Select HP-IB Menu Adrs Menu My
Atis.
The active entry area indicates the present decimal address. If the
number displayed is not 19, reset it to 19.
Press
@
(9)(ENTER). If the synthesizer 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

An asterisk denotes the selected interface language. If an asterisk is
not next to the SCPI key label, select Power
