A digital test apparatus for testing an analog semiconductor device includes a low pass filter which passes only a low frequency analog signal from among analog signals output from the analog semiconductor device, a rectifying unit connected to the low pass filter for converting the analog signal output from the low pass filter into a DC voltage, a high pass filter which passes only a high frequency analog signal from among analog signals output from the analog semiconductor device, a high frequency power detecting unit connected to the high pass filter for converting the analog signal output from the high pass filter into a DC voltage, and a digital measuring unit which is connected to the rectifying unit and the high frequency power detecting unit and measures the DC voltages to determine whether the analog signals output from the analog semiconductor device are desirable.
