Approximate input impedance (//164pF) for reference:
At direct input
50Vac (typical) from quiescence:
>8M

@ 50Vac
At direct input >>50V (typical) from quiescence:
Initial impedance is approximately 2.1k
. Impedance increases abruptly within a
fraction of a second as display voltage (hard signal) is much higher than 50V (typical).
Final impedances vs display voltages typically are:
