Voltage measurement in 50 ohm input impedance of high speed digitzer

[newbee9201]

Hello,

I want to measure voltage into 50 ohm input impedance of in high speed digitizer.

bandwidth of signal is upto 500Mhz and voltage is upto 250V peak.

Before buying digitizer, I checked effect of input impedance as 50 ohm, voltage used here 230V AC using active diffrential probe.

DSO showed 183V instead of 230V in 50 ohm termination.

I believe same thing will happen with digitizer, then how can i measure correct values in digitizer, cause it do not have 1Mohm input impedance.

500 MHz and up to 250 V into a 50 Ohm load?  Shure?

Get a 1.5 kW  20dB attenuator 😄 

Current  can make you small, black and ugly ...  

However I have the impression that you want something different... but dealing with high voltage and not really cheap digitizers  and don't know how to ask questions or define your requirements ....
