Perform the following steps:
1. Select the DAC with the following command:
INST:SEL DAC
2. Enter the following command to set the number of data points used in the
waveforms:
TRACe:POINts 32
3. Enter the next command to set the sample rate for the waveforms:
TRACe:SRATe 2000
4. Enter the following command to create a Ramp waveform on Channel one:
TRACe1,1,0,.625,1.25,1.875,2.5,3.125,3.75,4.375,5,5.625,6.25,
