I hope this is true, however this probe work perfectly for the big DPO7254 where its input capacitance is 13pF. There is no strim on the x100 probe.rather old Gould probe being designed for a scope with much higher input capacitance (30pF) whereas the 4227 has about 15pF input capacitance
Thank you for this, the generator is isolated, I only work with the low voltage arm (but still high for me and the scope!). I tried one active HV differential probe and also a 20db attenuator but what I recieved is not the impulse.Apart from that, please be very careful, +/-1MV is a lot of voltage, both for you and the scope!
