On the ETS364 / ETS88 family of testers, the APU-12 max sampling rate is 100 Kilo samples per second (Ksps) and the DPU-16 digital pattern sampling rate is 132 Mega samples per second (Msps). If a particular test method needs to use the digital sampling rate, then that rate will be limited to 100Ksps and it can cause longer digital pattern run time. It is not a good test method for production, so reducing test time and getting the same results will be important!

In this paper, the author will share another test method to reduce digital pattern run time and have the same APU-12 digitizer result (compare with old test method).

This paper will share the results, a comparison between the old and new method, and how much test time can be reduced.
