Figure 2.15. Circuit Model Corrected for FGEN Output Impedance
Just considering the case where you used a DC signal source, you can now simulate the circuit again. Figure 2.16 shows
the results of your new circuit model.
Figure 2.16. DC Voltage Measurements of the Corrected Circuit Model
From Figure 2.16, you can see that you now measure 3.898 V across your simulated circuit, which is much more aligned
with the measurements that you took with the DMM (3.909 V). Repeating the same process with your AC signal (5 Vpp,
60 Hz sine wave), you can see from Figure 2.17 that you now measure 1.378 V
rms
across your simulated resistor network,
which is again closer to the actual value you measured with the DMM.
