Abstract

PURPOSE:To test a device to be tested, by picking up a control signal of facsimile pre-stored from a storage device and applying it to the facsimile device through playback. CONSTITUTION:A control signal of facsimile transmitted from an MODEM passes through an amplifier 1 and converted into a digital signal from an analog signal with an A/D conversion circuit 2, and stored in an RAM3. The digital signal stored in the RAM3 is converted into an analog signal at a D/A conversion circuit 4, attenuated at an attenuator 5 and applied to a facsimile device to be tested. The output of an attenuator 6 can monitor a control signal transmitted from a device to be tested with an amplifier 6 and a speaker 7 and a signal transmitted from this test device.
