Generating DC Voltages
HP IBASIC Program Example (DCVOLTS)
43
Generating Standard Waveforms with the HP E1340A
This program outputs a +5 V DC voltage. The commands are:
1. Reset the AFG -
*RST
The
*RST
command aborts any waveform output and selects the
sinusoid function.
2. Select the Function -
[SOURce:]FUNCtion[:SHAPe] DC
This command selects the DC function.
3. Set the Amplitude -
[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude] <
This command specifies the amplitude. Refer to the section called
" Selecting the Amplitude Levels and Output Units" on page 50 for
more information.
