Description
Technical field
The present invention relates to a kind of coupling circuit, especially relate to a kind of coupling circuit for pulse generator and equipment under test power supply.
Background technology
In 7637 serial newest standards, new regulation has been had to the P5 waveform of simulation throw load, require that the output P5 superimposed pulses of simulator is on the power supply of tested device, is then supplied to tested device, to check the antijamming capability of tested device when throw load.
And the generation of P5 pulse, what scheme no matter can have different schemes, be, last result be all the impulse waveform of output to be superimposed upon by be equipment power supply on, we are called coupling this process.The mode of coupling has a lot, has capacitive coupling, the modes such as inductance coupling high.Because P5 pulse also has otherwise constraint, the coupled modes of inductance or electric capacity are difficult to realize in pulse-generating circuit, even if can realize, also cannot ensure the harmless transmission of energy, and inductance and electric capacity can change the internal resistance of generator.Therefore a kind of satisfactory coupling circuit arises at the historic moment.
Summary of the invention
Object of the present invention is exactly provide a kind of coupling circuit for pulse generator and equipment under test power supply to overcome defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions:
A kind of coupling circuit for pulse generator and equipment under test power supply, this circuit is connected with equipment under test power supply with pulse generator respectively, it is characterized in that, described coupling circuit comprises diode D1, diode D2, diode D3, diode D4, signal positive output end and signal negative output terminal, the described positive pole of diode D1 is connected with the output plus terminal of pulse generator, the negative pole of described diode D1, the negative pole of diode D2 is connected with signal positive output end respectively, the positive pole of described diode D2 respectively with the output negative terminal of pulse generator, the negative pole of diode D3, the negative pole of diode D4 connects, the positive pole of described diode D3 is connected with equipment under test positive source, the positive pole of described diode D4, equipment under test power cathode, the equal ground connection of signal negative output terminal.
Compared with prior art, the present invention has the following advantages:
Make use of the one-way conduction characteristic of diode dexterously, achieve under so special environment that pulse generator and tested device power supply are coupled and be coupled, both useless to inductance, also useless to electric capacity; Neither change the internal resistance of pulse generator, also do not affect the power supply facilities of tested device; The more important thing is the output energy that can not change pulse; Circuit structure is simple and practical.
Accompanying drawing explanation
Fig. 1 is physical circuit figure of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in Figure 1, a kind of coupling circuit for pulse generator and equipment under test power supply, this circuit is connected with equipment under test power supply with pulse generator respectively, described coupling circuit comprises diode D1, diode D2, diode D3, diode D4, signal positive output end and signal negative output terminal, the described positive pole of diode D1 is connected with the output plus terminal of pulse generator, the negative pole of described diode D1, the negative pole of diode D2 is connected with signal positive output end respectively, the positive pole of described diode D2 respectively with the output negative terminal of pulse generator, the negative pole of diode D3, the negative pole of diode D4 connects, the positive pole of described diode D3 is connected with equipment under test positive source, the positive pole of described diode D4, equipment under test power cathode, the equal ground connection of signal negative output terminal.
This coupled modes both can not change the internal resistance of pulse generator, also can not have an impact to the power supply of EUT.The program is such: the positive pole of the power supply of tested device receives the output negative terminal of pulse generator by a diode, the negative terminal of pulse generator is also connected by a diode with its anode, like this, just for power supply provides a path, the negative pole of tested device power supply is connected with the earth, the earth is also connected by a diode with the negative terminal of pulse generator, before pulse is for arrival, power supply can normally for tested device be powered, when pulse arrives, pulse is just coupled on the power supply of tested device.Thus achieve being coupled of P5 pulse and tested device power supply.
