Theory of Operation

There are no user replaceable parts within the probe or the
compensation box; however, this theory of operation is provided to
assist you in isolating failures to either the probe or the host
oscilloscope. Refer to Figure 4–1 for the probe's simplified
schematic.

Probe Head and Cable Assembly

The probe head assembly contains an active amplifier circuit that
buffers and amplifies the input signal. The amplifier receives power
and an offset level from the compensation box assembly via the
cable assembly.
