Analog (DAC) Output using DAQ-2543 or DAQ127/128


Combines with a fast Digital To Analog Converter (DAC), MINI-MAX/51-C2 can act as a signal generator, producing arbitrary waveforms. This example generates a periodic ramp ( sawtooth waveform ) using the LTC1663 DAC from Linear Technology on DAQ-2543 and DAQ-127/128 boards.

main()
