shows the probe head, together with the optional clip-on x l0
attenuator tip, which extends the input range to 10mV to 2V per
division (in 1, 2, 5 steps) and the common mode linear dynamic
range to +50V.
While a 10:1 passive divider probe greatly reduces loading on the
circuit under test compared with a similar length of screened cable,
its effect at high frequencies is by no means negligible. Figure 10.5 ...
