3 APPLy Commands
38 U2761A Programmer’s Reference
APPLy:USER
Syntax
APPLy:USER [<frequency> [,<amplitude> [,<offset>] ]]
This command outputs a user- defined Arbitrary waveform with the
specified frequency, amplitude, and DC offset. The waveform is output as
soon as the command is executed.
Parameters
Remarks
The maximum amplitude will be limited if the waveform data points do
not span the full range of the output Digital- to- Analog Converter (DAC)
from –8191 to +8191. Refer to Chapter 10, “Arbitrary Waveform
Commands” on page 103 for more information on downloading Arbitrary
waveforms to memory.
Example
The following command sets the output frequency to 1 kHz, output
amplitude to 2 Vpp, and output offset to 0 V.
APPL:USER 1000, 2 VPP, 0
Item Type Range of values Default value
