Hello guys,
Appreciate your comment about why the below results are happening.
I've recently got the ADALM2000 and have been testing my lab assignments in Scopy v1.1.2. I am testing the following multisim setup at 1.76Vrms (5Vpp)
However, the Vrms I get in Scopy (~590mV) are not what I was expecting (~1.7Vrms)... Sine source of 5Vpp at 1kHz.
In several other experiments it's the same situation: the Vpp and Vrms results are Not what I was expecting in my calculations and multisim simulations.
This voltage discrepancy only happens with AC, not DC.
Thank you
The signal generators (AWG) in the M2k have 50 ohm source impedance. In your simulation you are using an ideal voltage source (I'm guessing with 0 ohms source impedance) driving 21 ohms as the load. Try…

Thank you very much Doug,
I'll will be considering the source impedance in the future.
This is the simulation reading results:
