1. SOUR:WAVE:FUNC <name>
As soon as this command is received, the waveform takes effect. After the wave
mode is armed (SOUR:WAVE:ARM), the SOUR:WAVE:INIT command is
required to start the function output. For ARBitrary, X = 0-4. If no X is supplied,
then ARB0 is selected. Location 0 is the volatile waveform memory location. If
this command is sent when the waveform is armed, the Model 6221 will re-arm
itself. If the waveform must be reloaded while the output is enabled, the inactive
value will be output during this period.
An error +525 Cannot save ARB0 as user setup is returned when you try to
save a setup with the WAVE function set to ARB0. This limitation is necessary
because ARB0 is stored in volatile memory and will not be valid after the unit is
power-cycled. When you attempt to do so, the WAVE function will be changed
to SINE (default), this error will be generated, and the save will then proceed
normally.
