d
25 V/ns Differential Input
DC Attenuation ~2.2:1 (–6.9 dB)

Propagation Delay ~6.15 ns
a Decreased rise and fall times mainly due to phase correction performed in the DSO80000 series, not due to DSP
boosting (except in DSO81304A).
b Vcm_term is the voltage supplied to the common mode termination port of the N5380B. If a shorting cap is in place, this
voltage is zero.
c SR max of sine wave = amplitude x 2 x p x frequency OR SR max of a step approximately equal to the amplitude x
0.6/trise (20-80%).
d Use of X:1 SMA coaxial attenuators in front of SMA probe head will: 1) Increase by X the max input signal slew rate,
dynamic range, offset range, common mode range, noise referred to the input, DC attenuation, and maximum input
voltage, 2) Most likely improve return loss or input TDR if attenuators are high quality, and 3) Not affect bandwidth and
rise time if attenuators are high quality.
