That’s a brill video thanks. And shows exactly what mine was doing.
Another question. Without measuring what would you say is the max current draw I will be able to achieve from the sig gen? 100ma? Or does it depend on the frequency etc. New to sig gens. Many thanks
The signal generator has a 50 Ohm output, which means a 50 Ohm resistor in series with the output (between the output amplifier and the jack). So when it outputs e.g. 5 V (e.g. the peak of a 10 Vpp wave), into a short circuit, the current will be 5V/50R = 100 mA. The RMS current will be around 71 mA for a sine wave. The same signal into a proper 50 Ohm load will give 5V/(50R+50R) = 50 mA peak. The terminating resistor is in series with the source resistor.
In contrast to a power supply, which has a "zero" output impedance, drawing current from the 50 Ohm signal generator output will reduce the amplitude of the output.
