TDS Family Oscilloscope Programmer Manual
ALLOcate:WAVEform:REF<x>
Sets or queries the number of waveform data points for the specified reference
location. If an attempt is made to allocate memory when it is not available, an
execution error is generated and the memory is not allocated.
Save and Recall
= 0 is returned when the reference location is empty.
0 specifies the number of data points. Table 2–23 shows the number of
data points supported for reference locations by TDS model. In the TDS 5XXA
and 6XXA, all invalid values less than the maximum will be forced to the next
highest valid value, and those higher than the maximum will be forced to the
maximum. For example, 15002 points on a TDS 544A with option 1M will
allocate 50000 points of data for the reference. No complete references are stored
for 500000 data points in the TDS 7XXA.
