Problems solved by technology

The disadvantage is that the accuracy of the chip is very high, and the sensor is easily damaged. At the same time, this method is affected by factors such as the position of the optical fiber around the electrical pyrotechnics, the installation method, etc., and the stability is not very good.

Based on the closed-circuit conduction method, the method of measuring the radio frequency firing power of pyrotechnics is based on "GJB5309.13-2004 Test methods for pyrotechnics Part 13: Radio Frequency Sensitivity Test", using a radio frequency source with adjustable frequency and power, through conduction , through the impedance matching device, the power output by the RF source is injected into the foot of the EED, and the RF firing power of the EED is measured, but because it does not remove the RF power loss of the impedance matching device, the result is not injected into the EED. The real RF power of the product

The above method cannot measure the real radio frequency ignition energy of EEDs in real time
