Sending this program message sets the absolute value
of
the maximum amplitude
voltage. The amplitude voltage is at maximum when the selected trace pointis at
its minimum
or
maximum value. The value
of
a pointin trace memory affects the
output amplitude in the manner shown in the diagram below.

Bach point in Trace Memory contains a value in the range
ûOOh
(0) to FFFh (4095).
As
Trace Memory is scanned these values are converted to analog voltages for
output. The Arb is calibrated so the value 800h corresponds
ta
0 volts amplitude
and the values Oûlh and FFFh corresponds to the negative and positive full scale
amplitude voltages.
The point value
OOOh
will generate an output voltage slightly more negative than
the programmed amplitude. Limit your point values to the range 001h
to
FFFh
if
you want trace amplitudes to be symmetrical about 0 volts.
AIl internally generated traces
of
a cyclical nature (SINusoid, SQUare, TRIangle,
..
, etc.) are generated such that their most negative point has a value
of
OOlh
and
their most positive point has a value
of
FFFh. This makes their amplitude voltages
symmetrical about 0 volts and the absolute value
of
their peak voltages equal to the
programmed amplitude. The 'MINimum' amplitude is 0.0Vp, the 'MAXimum'
amplitude is 5.0Vp.
