Abstract
A kind of palm oscillograph, comprise probe, attenuator circuit, AD sample circuit, DSP data processor and bluetooth sending module, the signal that described probe gets is successively by being sent to DSP data processor processes after attenuator circuit, AD sample circuit, and signal is sent to mobile phone by bluetooth sending module by described DSP data processor.Utility model works principle: probe, attenuator circuit, AD sample circuit, DSP data processor and bluetooth sending module are integrated on one piece of little circuit board, as Waveform generator; Then utilize mobile phone as display screen, the two just can form a complete oscillograph after combining, and volume is little, is convenient for carrying.
Description
Technical field
The utility model relates to teaching experimental tool.
Background technology
Oscillograph is a kind of purposes electronic measuring instrument very widely.It can become invisible converting electrical signal observable image, is convenient to the change procedure that people study various electrical phenomena.Oscillograph utilize narrow, by the molecular electron beam of High-speed Electric, beat on the panel scribbling fluorescent material, just can produce tiny luminous point (this is the principle of work of traditional analog oscilloscope).Under the effect of measured signal, electron beam just looks like the nib of one-pen, can depict the change curve of the instantaneous value of measured signal on panel.Utilize oscillograph can observe the time dependent squiggle of various unlike signal amplitudes, various different electricity can also be tested, as voltage, electric current, frequency, phase differential, AM depth etc. with it.Existing laboratory is all furnished with special oscillograph, and traditional oscillograph volume is comparatively large, is inconvenient to carry.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of palm oscillograph, and volume is little, is easy to carry.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of palm oscillograph, comprise probe, attenuator circuit, AD sample circuit, DSP data processor and bluetooth sending module, the signal that described probe gets is successively by being sent to DSP data processor processes after attenuator circuit, AD sample circuit, and signal is sent to mobile phone by bluetooth sending module by described DSP data processor.Utility model works principle: probe, attenuator circuit, AD sample circuit, DSP data processor and bluetooth sending module are integrated on one piece of little circuit board, as Waveform generator; Then utilize mobile phone as display screen, the two just can form a complete oscillograph after combining, and volume is little, is convenient for carrying.
The beneficial effect that the utility model is compared with prior art brought is:
Probe, attenuator circuit, AD sample circuit, DSP data processor and bluetooth sending module are integrated on one piece of little circuit board, as Waveform generator; Then utilize mobile phone as display screen, the two just can form a complete oscillograph after combining, and volume is little, is convenient for carrying.
Accompanying drawing explanation
Fig. 1 is the utility model circuit structure block diagram.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Figure 1, a kind of palm oscillograph, comprise probe, attenuator circuit, AD sample circuit, DSP data processor and bluetooth sending module, the signal that described probe gets is successively by being sent to DSP data processor processes after attenuator circuit, AD sample circuit, and signal is sent to mobile phone by bluetooth sending module by described DSP data processor.Utility model works principle: probe, attenuator circuit, AD sample circuit, DSP data processor and bluetooth sending module are integrated on one piece of little circuit board, as Waveform generator; Then utilize mobile phone as display screen, the two just can form a complete oscillograph after combining, and volume is little, is convenient for carrying.
