) 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
Volt*Hertz Product ≤8 × 10

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 Front-panel input: 1100 VPEAK or 400 VDC on all ranges
Rear-panel input through the plug-in modules: 600 V
PEAK
on all ranges (note this level exceeds the
maximum input signal for modules; see Maximum Input Signal Levels for 7700 Series plug-in modules

Maximum DCV 400 V on any ACV range
ACV Frequency Frequency reading automatically returned in reading buffer when in full buffer mode.
Frequency readings are specified as in the frequency and period table.
