Input Step Change Tests
Influence Quantity Range
Signal Magnitude 100% of PMU nominal voltage / current
Frequency 44.0 Hz to 65.9 Hz
Phase Shift ±180 °
Phase Step Magnitude 0 ° to ±180 °
Amplitude Step Magnitude

Notes:
[1] - Positive amplitude step cannot exceed the 6135A range limit. See the 6100B/6105A Users Manual for details.
[2] - PMU response and delay times are small relative to PMU reporting intervals so multiple steps are staggered to increase the
resolution of the measurement.
