[SOURce:]RAMP
The [SOURce:]RAMP subsystem selects the polarity of ramp waveforms, and the
number of points on generated ramps and triangle waveforms.
Subsystem Syntax [SOURce:]
RAMP
:POINts <
number>
:POLarity <
polarity>
:POINts
[SOURce:]RAMP:POINts <number> specifies the number of points to be used to
generate the stepped ramp or triangle waveform.

Units
<
number> numeric see below | MINimum | MAXimum none
The valid range for <
number> is 4 through the length of the largest available contiguous
piece of waveform segment memory.
MINimum selects 4 points; MAXimum selects the largest available contiguous piece of
waveform segment memory or 262,144 points, whichever is less (4 points minimum).
Comments • For triangle waves, make <number> a multiple of 4 for best waveform shape.
• When [SOURce:]FUNCtion[:SHAPe] RAMP or TRIangle is selected, the greater of
the
[SOURce:]RAMP:POINts value and 8 points of contiguous waveform segment
memory must be available. When
[SOURce:]FUNCtion[:SHAPe] SQUare is
selected, 8 points of contiguous waveform segment memory must be available.
Attempting to select one of these functions with less contiguous waveform segment
memory available, or to set
[SOURce:]RAMP:POINts to a value larger than the largest
contiguous amount of available waveform segment memory when ramp or triangle
wave output is selected, will generate Error +1000,"Out of memory".
