U3401A User's and Service Guide
• AC+DC coupled true RMS — measure the AC component with up to 400 VDC bias on any
range
• Maximum 3:0 at full scale
• 1 MΩ in parallel with <100 pF
• 1000 V RMS / 1400 V PEAK
7
• 2x10 V-Hz product on any range, common mode input
6
• 1x10 V-Hz product on any range, normal mode input
• Will select higher range if peak input overload is detected during autoranging. Overload is
reported in manual ranging.
• 1000 V RMS on all ranges
• Approximate 1.5 second when the displayed reading reaches 99.9% AC RMS value of the
tested input signal at the same range.
