Hi
What does it mean when it says that a signal generator (or, some other equipment) has an output impedance of 600Ω?
For example, theoretically, an op-amp has infinite input impedance and zero output impedance. To me, this means that an op-amp needs extremely low current from the signal applied to its input but it can deliver, ideally, infinite current to anything connected on its output.
So, perhaps, it means that a signal generator always has its own internal impedance of 600Ω in series with any load connected to its output.
Please help me with it. Thank you.
Regards
PG
