U3402A User’s and Service Guide 103
Measurement Specification
AC voltage
Measurement method
AC 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 M
W
± 2% in parallel with <120 pF on all ranges
Maximum input voltage
750 V RMS /1100 V PEAK
2x10
7
V-Hz product on any range, normal mode
input
1x10
6
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 1.5 seconds when the displayed
reading reaches 99.9% AC RMS value of the
tested input signal at the same range.
