Abstract

This circuit together with a computer and a multiplexer allows the computer to measure, check and display all front end signals of the test system automatically. The circuit requires a repetitive signal and sync pulse for reference, which has a firm relationship to the signal. The circuit mainly consists of logic, which supplies a fast analog detector with a reference voltage and a clock signal which defines at what time the signal is compared with the reference voltage. The reference voltage and the clock pulse can be updated automatically to find a compare with the signal. This circuit allows different modes: 1. Set reference voltage, find time. 2. Set time, find reference voltage. 3. Set reference voltage, set and modify time, store detector output. 4.
