AC Voltage Specifications

AC Voltage specifications are for ac sinewave signals >5 % of range. For inputs from 1 % to 5 % of range and <50 kHz,
add an additional error of 0.1 % of range, and for 50 to 100 kHz, add 0.13 % of range.
Maximum Input...................................................... 750 V rms or 1000 V peak (8845A), 1000 V rms or 1414 V peak
Measurement Method ........................................... AC-coupled true-rms. Measures the ac component of input with up to
AC Filter Bandwidth:
Slow .................................................................... 3 Hz – 300 kHz
Medium ............................................................... 20 Hz – 300 kHz
Fast ..................................................................... 200 Hz – 300 kHz
Common Mode Rejection..................................... 70 dB at 50 Hz or 60 Hz 0.1 % (1 k unbalance)
Maximum Crest Factor ......................................... 5:1 at Full Scale
Additional Crest Factor Errors (<100 Hz) ........... Crest Factor 1-2, 0.05 % of full scale
