Abstract

The invention relates to a circuit signal detection device for detecting an electrical signal. The device comprises a time sequence generating circuit, an advance signal output detection circuit, a peak pulse detection circuit, a logical error detection circuit and a data processing circuit. By applying the same test conditions to a standard circuit and a detected circuit at the same time and conducting work, comparison test on the output signals of the standard circuit and the detected circuit as well as comparison test control are performed by use of adjustment of the output time sequences of the detected circuit and the standard circuit; and the advance signal output detection circuit, the peak pulse detection circuit, the logical error detection circuit, a low-level parameter shift detection circuit and the data processing circuit detect whether the advance signal output, peak pulse output, logical error output, low-level parameter shift and zero-level output exist on the detectedcircuit so as to check correctness of the output signal.
