Hello Forum,


I've keyword searched the scope forum here and still have not found exactly what I am looking for. As the topic says it all, I'm trying to determine what probe attenuation ratio will show the actual circuit voltage.


I understand that reading higher voltages in circuits is followed suit by greater probe attenuation at the scope probe setting. My question is this:


In reading the Measurements (Amplitude) on the scope with a attenuation rate set at 10:1 am I seeing the true circuit voltage or is this reading nulled by a factor of 10? Taking in to account the voltage being measured and applying the correct probe attenuation I am looking for a "best setting" that will truly represent the circuit voltage present at the probe tip. I hope I didn't confuse myself.


Any assistance is greatly appreciated from the community.
