scope:

This standard is applicable to digital recorders and digital oscilloscopes used for measurements during tests with high-impulse voltages and high-impulse currents. It covers the measuring characteristics and calibrations required to meet the measuring accuracy specified in IEEE Std 4-1995 and IEEE Std C57.98-1993 [B10].

The characteristics of general-purpose digital recorders are covered in IEEE Std 1057-1994 [B9]. General methods of pulse measurement are covered in IEC 60469-1 (1987-12) [B4] and IEC 60469-2 (1987-12) [B5].

This standard

a) Defines the terms specifically related to the digital recorders used for monitoring high-voltage and high-current impulse tests;

b) Specifies the necessary performance characteristics for such digital recorders to ensure their compliance with the requirements for high-voltage and high-current impulse tests;

c) Describes the tests and procedures that are necessary to show that these performance characteristics are within the specified limits.
