Agilent Technologies E1441A user service APPLy:DC, APPLy NOISe, APPLy:RAMP, APPLy:SINusoid

Comments • Four low-level commands are required to program the function generator with the same output as the APPLy syntax example.

"FUNC:SHAP SIN"	Select the function wave shape
"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

APPLy:DC

[SOURce:]APPLy:DC[<frequencyDEF>[,<amplitudeDEF>[, <offset>]]] is used to output a dc voltage with the amplitude level specified by the offset parameter.

Comment The frequency and amplitude parameters are ignored in this command but you MUST specify a value or "DEF". If values are specified, they are stored and used when you make a subsequent function change without specifying new frequency or amplitude values. For example, to output a +5V dc voltage, execute the following command:

"APPL:DC DEF, DEF, 5"

APPLy:NOISe

[SOURce:]APPLy:NOISe [<frequencyDEF>[,<amplitudeDEF>[, <offset>]]] is used to output noise with the specified amplitude and dc offset.

Comment The frequency parameter is ignored for this command but you MUST specify a value or "DEF" to allow the command to accept the amplitude and offset parameters. If you specify a frequency value, the value is remembered when you change to a different function. For example:

"APPL:NOIS DEF, 3.0, -2.5"

APPLy:RAMP

[SOURce:]APPLy:RAMP [<frequency>[,<amplitude>[,<offset>]]] is used to output a ramp wave with the specified frequency, amplitude, and dc offset. For example, a ramp wave with the same parameters as the syntax example is shown below:

"APPL:RAMP 5.0E+3, 3.0, -2.5"

APPLy:SINusoid

[SOURce:]APPLy:SINusoid [<frequency>[,<amplitude>[,<offset>]]] is used to output a sine wave with the specified frequency, amplitude and dc offset. For example, the command for a sine wave shown in the syntax example for a 5 kHz, 3 Vpp with -2.5Vdc offset is repeated below:

"APPL:SIN 5.0E+3, 3.0, -2.5"
