发明名称 Precision semiconductor device timer
摘要 A microprocessor controls a programmable oscillator, directing it to produce digital pulses of variable width and frequency. The microprocessor generates inputs for the device under test and compares its outputs after one clock cycle with expected outputs. The clock cycle is adjusted repeatedly until the device's time to complete is known. Response times for the system both with and without the device under test are measured and the difference reported.
