Abstract Accurate transfer function is necessary to analyze the change information of earth tide for a long time, the transfer function can only be calculated with circuit principle as the accuracy of the deformation instruments is very high. The transfer function of DSQ tiltmeter was determined with step test method, while the output data between obtained were comparied with laser interferometer and water tiltmeter. Therefore, the transfer function could be more accurate.
Key words ：
transfer function
laser interferometry
step response
