Im trying to get the cut-off frequency at the capacitor of this EKG assignment we are completing for class, I completed the by hand solutions but im not sure on how to get frequency response simulation in pspice, I tried the trace ----> Measurements but I keep getting an error.

It is ac analysis.

.AC LIN NP FSTART FSTOP
.PROBE
I think i got it but the frequency seems to be off from my calculated, im getting a cutoff at around 100Hz but my calculated was 15.92hz, my voltage gain seems to be right

I am getting cutoff at 52 kHz.
Max amplitude of -61.284 dB, -61.284 dB-3 dB=-64.284 dB this is where we look for cutoff frequency. At -64.32 dB I get 52.784 kHz.
