ABSTRACT:
A multifunctional circuit analyzer is disclosed which is capable of determining the complete signature of an unknown electrical signal. The circuit analyzer utilizes a high and low peak detection circuit and an analog to digital converter to determine the outer limits of the signal. The high and low threshold voltages are selected between the limits of the signal. Each time the unknown electrical signal passes through the preset high or low threshold voltage, a high or low threshold digital signal occurs. A logic circuit operates on these high and low threshold digital signals and activates the start and stop gate signals. These gate signals allow a time base signal to pass through a gate circuit into a series of decade counters. The information in the counters are thereafter transferred into decoders and then multiplexed to a display. The multifunctional circuit analyzer disclosed is capable of measuring, rise time, fall time, frequency, duty cycle, TRC counting, width, period, coincidence of two signals, the interval between two signals, count functions, frequency ratio, AC volts, DC volts and resistance.
