16 4000 X-Series Oscilloscopes Service Guide
1 Characteristics and Specifications
Transient Withstand Capability
CAUTION
Maximum input voltage for analog inputs
CAT I 300 Vrms, 400 Vpk; transient overvoltage 1.6 kVpk
50 Ω input: 5 Vrms Input protection is enabled in 50 Ω mode and the
50 Ω load will disconnect if greater than 5 Vrms is detected. However
the inputs could still be damaged, depending on the time constant of
the signal. The 50 Ω input protection only functions when the
oscilloscope is powered on.
With 10073C 10:1 probe: CAT I 500 Vpk, CAT II 400 Vpk
With N2871A, N2872A, N2873A 10:1 probe: CAT I 400 Vpk, transient
overvoltage 1.25 kVpk, CAT II 300 Vpk
CAUTION
Maximum input voltage for logic channels:
±40 V peak CAT I; transient overvoltage 800 Vpk
