Hi everyone,
I am using a signal generator in series with a RLC circuit, generating an AC signal at 1kHz.
I have my probes connected across the resistor
When I change the timescale the Fres bandwidth changes on the spectrum analyzer.
At 1mS the resonant bandwidth is from 25kHz-50kHz
At 2mS the resonant bandwidth is 13kHz-24kHz
At 5mS the resonant bandwidth is 4.9-9kHz
Can anyone here explain why the resonant bandwidth is changing when I change the timescale on the spectrum analyzer? And how I can find the actual resonant frequency of the circuit?
Am I doing something wrong here?
