    Default Question on Power Measurements from Scope Vs Meter

    Let's say a meter that updates 10 times a second is being used to measure power. Every 1/10 of a second when the number updates, is that number representative of the instantaneous power at that moment or the average power over the span of 0.1 seconds?

    Same question applies to a scope. Let's say the oscilliscope updates like 1000 times a second. Is that power at a single point actually the instantaneous power at that point in time, or rather is it a generally good representation of instantaneous power while technically being average power over 0.001 seconds?

    Depends on how it's set. Could be peak, could be RMS, could be captured at that moment.
