GB/T 38888-2020 (English Version) PDF

Scope: This standard specifies the performance characteristics and calibration methods of data acquisition software. This standard covers: - the DAQ manufacturer provides a minimum specification describing the performance of the DAQ's analog-to-digital module (ADM); - the standard test strategy used to verify the minimum specification requirements; - the minimum required ADM stored on the DAQ Calibration Information; Minimum calibration software requirements for external calibration and self-calibration of ADMs for one-DAQ. This standard applies to DAQ for low-frequency signal-to-signal conversion. Example: Low-frequency signal conversion applied in equipment control, vibration measurement, vibration diagnosis, acoustics, ultrasonic measurement, temperature measurement, pressure measurement, power electronics measurement, etc.
