ABSTRACT:
An analog-to-digital converter test system and method 10 is provided that comprises a digital-to-analog converter system 26. An analog-to-digital converter system 32 is tested using an internal analog input signal 30 generated by the digital-to-analog converter system 26. The digital-to-analog converter system 26 generates the internal analog input signal 30 from an internal digital input signal 24 generated by a programmable data ramp controller 14. The programmable data ramp controller 14 produces a high precision internal digital input signal 24 with predetermined start and stop voltage values 16 repeated over a fixed frequency determined by a programmable divide circuit 18.
