Simplified Programming Overview
This section gives an overview of the basic techniques used to program
the function generator over the remote interface. This section is only an
overview and does not give all of the details you will need to write your
own application programs. Refer to the remainder of this chapter and
also chapter 6, “Application Programs”, for more details and examples.
Also refer to the programming reference manual that came with your
computer for details on outputting command strings and entering data.
Using the APPLy Command
The
APPLy
command provides the most straightforward method to
program the function generator over the remote interface. For example,
the following statement executed from your computer will output a
3 Vpp sine wave at 5 kHz with a -2.5 volt offset:
"APPL:SIN 5.0E+3, 3.0, -2.5"
Using the Low-Level Commands
Although the
APPLy
command provides the most straightforward
method to program the function generator, the low-level commands give
you more flexibility to change individual parameters. For example, the
following statements executed from your computer will output a 3 Vpp
sine wave at 5 kHz with a -2.5 volt offset:
"FUNC:SHAP SIN"
Select sine wave function
"FREQ 5.0E+3"
Set frequency to 5 kHz
"VOLT 3.0"
Set amplitude to 3 Vpp
"VOLT:OFFS -2.5"
Set offset to -2.5 Vdc
