Testing the stability of the low bits of the DAC.
|
|
|
|
We have a 10-bit DAC that we are commanding with 10 bits, and want to
|
|
find out the precision of each command, ie. to what precision we can
|
|
predict the actual output of the DAC for each command.
|
|
|
|
Test setup: 10-bit DAC, scaled to about ±5V, measured as a voltage by
|
|
the Keithley 2002.
|
|
|
|
We ran dactest.c for about 16 hours to write random DAC values and
|
|
accurately measure their output.
|
|
|
|
process.m calculates, for each of 1024 commanded value, the average,
|
|
min, max, and standard deviation of the measured voltages.
