Channel-to-Channel
Common Mode
Rejection, typical
100:1 at frequencies ≤50 MHz, measured on MATH Ch1 – Ch2
waveform, with test signal applied between signal and common
of both channels, and with the same VOLTS/DIV and coupling
settings on each channel
Channel-to-Channel
Crosstalk, typical
≥100:1 at 50 MHz, measured on one channel, with test signal
applied between signal and common of the other channel, and
with the same VOLTS/DIV and coupling settings on each channel

Capacitance, typical
55 pF
