AC Voltage Characteristics
Overrange (voltages in V
RMS
) 20% on 100 mV, 1 V, 10 V, and 100 V ranges. 0% for 750 V range
AC Measurement Method AC-coupled digital sampling with anti-alias filter
Crest Factor (excludes sine wave) Crest factors of up to 3:1 at full-scale input or 10:1 maximum, whichever is greater.
Autorange selects optimum range for crest factor up to 10:1.
Accuracy specifications apply to all crest factors and are limited to a product of (crest factor) ×
(fundamental frequency) ≤ 3 kHz.

Common Mode Rejection Ratio >70 dB, for 1 kΩ unbalance in LO lead
Detector Bandwidth Setting of 3 Hz, 30 Hz, or 300 Hz sets maximum measurement aperture of 200 ms, 20 ms, or 2 ms,
respectively; only signals with frequency greater than the detector bandwidth are measured.
Input Impedance 1.1 M Ω ±2%, in parallel with <100 pF
Input Protection 110 0 V
