Using the APPLy Command

APPLy:NOISe [<frequency|DEFault> [,<amplitude> [,<offset>] ]]

Output Gaussian noise with the specified amplitude and dc offset.

The waveform is output as soon as the command is executed.

•The frequency parameter has no effect for this command but you must

specify a value or “DEFault” (the noise function has a 50 MHz

bandwidth). If you specify a frequency, it has no effect on the noise

output, but the value is remembered when you change to a different

function. The following statement shows the use of the APPLy

command for noise.

APPL:NOIS DEF, 5.0, 2.0

APPLy:DC [<

frequency

|DEFault> [,<

amplitude

>|DEFault> [,<

offset

>] ]]

Output a dc voltage with the level specified by the offset parameter.

You can set the dc voltage to any value between ±5 Vdc into 50 ohms or

±10 Vdc into an open circuit. The dc voltage is output as soon as the

command is executed.

•The frequency and amplitude parameters have no effect for this

command but you must

specify a value or “DEFault”. If you specify

a frequency and amplitude, they have no effect on the dc output,

but the values are remembered when you change to a different

function. The following statement shows the use of the

APPLy

command

for a dc output.

APPL:DC DEF, DEF, -2.5

APPLy:USER [<frequency> [,<amplitude> [,<offset>] ]]

Output the arbitrary waveform currently selected by the FUNC:USER

command. The waveform is output using the specified frequency,

amplitude, and dc offset. The waveform is output as soon as the

command is executed. See page 198 for more information on downloading

arbitrary waveforms to memory.
