6 Specifications and Characteristics

100 U3402A User’s and Service Guide

• Response time

• Approximately 1.5 seconds when the displayed reading reaches 99.9% AC RMS value of the

tested input signal at the same range.

AC voltage (True RMS AC + DC Coupling Mode)

• Measurement method

• AC+DC coupled true RMS—measure the AC component with up to 400 VDC bias on any

range

• Crest factor

• Maximum 3:0 at full scale

• Input impedance

• 1 MW ± 2% in parallel with <120 pF of all ranges

• Maximum input voltage

• 750 V RMS /1100 V PEAK

• 2x10

V-Hz product on any range, normal mode input

• 1x10

V-Hz product on any range, common mode input

• Overload ranging

• Will select higher range if peak input overload is detected during autorange. Overload is

reported in manual ranging

• Input protection

• 750 V RMS on all ranges

• Response time

• Approximately 2.5 seconds when the displayed reading reaches 99.9% AC RMS value of the

tested input signal at the same range
