i have been analyzing signal response from a DUT (a resonator) using network function in waveforms. For comparison, i ran the same setup and parameters on the actuation signal using a lock-in amplifier (MFLI) separately. Both responses are attached below. So far i have been getting very similiar response (from frequency and phase shift perspective), but with a significantly different amplitude.

Hi,
i have been analyzing signal response from a DUT (a resonator) using network function in waveforms. For comparison, i ran the same setup and parameters on the actuation signal using a lock-in amplifier (MFLI) separately. Both responses are attached below. So far i have been getting very similiar response (from frequency and phase shift perspective), but with a significantly different amplitude.

(for some reason i kept failing to upload directly here
)
The parameters of the reference signal were:
Ampltude: 3V
DC-Offset: 2V
Frequency: 203.31 kHz
I am quite new to signal processing (especially working with an ADC), so i might miss some details that should have been taken into account.
Could someone help me explain, what could possibly influence the amplitude different shown on each response?
I appreciate your time and response greatly!
Regards,
Jody
