Syntax:
:ARBitrary:PREDefined<ws> <shape>, <start>, <length>,<scale>
Examples:
:ARB:PRED SIN,1,1e3,100
Considerations:
1) The start address and the length must meet the specification that. Start a Length - 1
≤
131,072
2) The 'scale' refers to the scaling of the waveform as a percentage of full scale. A scale of 100% will, under the
correct conditions, generate a waveform whose data values range from -8191 to +8191. These 'correct conditions'
are set by the 'offset' value. This offset is the value of the data at the start address, and determines the maximum
scale settable. The following table shows the data values required in order to achieve maximum scale.
