Abstract

The invention provides a signal tracing and generating device, belongs to the field of testing instruments, and particularly relates to a small, exquisite and simple signal tracing and generating device. The signal tracing and generating device is small, exquisite, simple and low in cost. The signal tracing and generating device comprises a cylinder and is characterized in that a metal pin is fixed at one end of the cylinder, a wire is arranged at the other end of the cylinder, and the wire is connected with a metal clamp. The lateral wall of the cylinder is provided with a switch and a headset jack. A circuit is arranged inside the cylinder.

Description

Technical field: [0001] The invention belongs to the field of testing instruments, in particular to a compact and simple signal tracing and generator. Background technique: [0002] The signal tracer is an instrument used to find the location of equipment failures such as audio equipment. When in use, inject an audio signal of a certain frequency at a certain point in the front stage of the audio circuit, and then use a signal tracker to detect whether the signal appears at a certain point in the rear stage. If the signal appears normal, it means that the signal path between the injection point and the detection point is normal. If no signal is detected or the signal is very weak, the fault is between these two points. [0003] Signal generators, also known as signal sources or oscillators, are widely used in production practice and in the field of science and technology. All kinds of wave curves can be expressed by trigonometric function equations. A circuit that can ge...
