The 81150A / 81160A represents amplitude values by 16,384 discrete
voltage levels (or 14-bit vertical resolution). The specified waveform data is
divided into samples such that one waveform cycle exactly fills waveform
memory (see the illustration below for a sine wave). If you create an
arbitrary waveform that does not contain exactly 16K or Sample
max
points,
the waveform is automatically “stretched” by repeating points or by
interpolating between existing points as needed to fill waveform memory.
81150A: Sample
max
= 524288 (512 k)
81160A 1 channel: Sample
max
= 262144 (256 k)
81160A 2 channels: Sample
max
= 131072 (128 k)
Since all of waveform memory is filled with one waveform cycle, each
memory location corresponds to a phase angle of 2/16,384 radians or 2/
Sample
max
radians.
