Arbitrary Waveform Generator
164
Source : This is the source of the signal to be captured and
stored into the built-in arbitrary waveform memory.
Date Type : This gives the user additional options on what
data to capture from the selected source and stored into
internal memory.
Note: Although screen data contains a total of 1200 pts,
the captured waveform will be reduced to 600
pts by recalculating and averaging the original
source data As a result, some source data f may
be lost. . If you want to store all 1200 pts, use
the SAVE/LOAD menu to save the data in a .CSV
format to an external storage drive, then load
the .CSV data from the ARB DATA menu into one
of the arbitrary waveform memory storage
locations.
Note: The captured waveform may look different from
the original source due to internal scaling, limited
by the vertical resolution of 8-bits and a sampling
rate of 40 MSa/s. The displayable vertical data
range is 28 to 228, (what you see on the screen)or
a total of 200 vertical pixels. The actual arbitrary
data is internally represented with 8-bit vertical
resolution or 256 pixels (ranging from 0 to 255),
