-The 5.6 MΩ series resistor is split up to reduce the voltage on each of them. The diode partially removes the noise spikes from the high voltage circuit.
+The 5.4 MΩ series resistor is split up to reduce the voltage on each of them. The diode partially removes the noise spikes from the high voltage circuit.
 
-This is the raw pulse at point A, about 2 V for 100 µs, then falling back to 0 V in the next several 100 µs. Remainings of the little noise spikes are still visible:
