The measurement for magnetic field was realized through Helium optical pumped magneto-dependent sensor together with detecting system.The traditional method of testing whether the detecting system works regularly or not was debugging after manufacturing the whole sensor.Resonance signal simulator was designed aiming at verifying the feasibility of detecting system.The magnetic resonance signal was generated in order to simulate the function of optical system.The feedback signal of detecting system could be measured in real time by the use of modulation domain measuring frequency.The laboratory tests show that the device is able to verify the feasibility of detecting system and its performance is sufficiently close to the helium optical pumped magneto-de-pendent sensor,in addition,it has the characteristics of high measuring accuracy,real-time,reliability,independent of working envi-ronment and low cost.
