Wrong voltage dysplay
I 'm new here and have little knowledge of thing. I have an pulse generator and would like to measure the signals with PicoScope. I have set the voltage of signal to 1V and can see that in analog oscilloscope as well. But picoScope shows me always 2V. What could be the cause?
Re: Wrong voltage dysplay
What is the output impedance of the pulse generator, and what is the input impedance of the analog oscilloscope ?

Re: Wrong voltage dysplay
Output impedance of the pulse generator is 50 ohms, and the input impedance of the analog oscilloscope is 50 ohms too.
Re: Wrong voltage dysplay
As our scopes have a 1 MOhm input impedance you would read a 1V output from a 50 Ohm pulse generator at around 2V.

Oh, sorry, i founded it. I must select 50 ohms dc
