The terms specifically related to the digital recorders used for making high-voltage and high-current impulse measurements are defined in this standard, which also specifies the necessary performance characteristics for such digital recorders to demonstrate their compliance with the requirements for high-voltage and high-current impulse tests, and describes the tests and procedures that are necessary to show that these performance characteristics are within the specified limits

This standard is applicable to digital recorders and digital oscilloscopes used for measurements during tests with high-impulse voltages and high-impulse currents, as defined in IEEE Std 4™-2013, IEEE Standard for High-Voltage Testing Techniques.6 It covers the measuring characteristics and calibrations required to meet the measuring accuracy specified in IEEE Std 4-2013 and IEEE Std C57.98™. The characteristics of general purpose digital recorders are covered in IEEE Std 1057™-2017 [B5]7. This standard includes the following: a) Definitions of the terms specifically related to the digital recorders used for making high-voltage and high-current impulse measurements b) Specifications of the necessary performance characteristics for such digital recorders to demonstrate their compliance with the requirements for high-voltage and high-current impulse tests c) Descriptions of the tests and procedures that are necessary to show that these performance characteristics are within the specified limits
