HP IBASIC Program Example (RAMPWAVE)
Chapter 2
6. Set the Offset -
[SOURce:]VOLTage[:LEVel][:IMMediate]:OFFSet <
This command specifies the offset. Refer to the section called
" Selecting the Amplitude Levels and Output Units" on page 50 for
more information.
7. Initiate the Waveform -
INITiate[:IMMediate]
This command generates an immediate output with the arm source
set to
IMMediate
. Refer to Chapter 5 for triggering information.
