To characterize the Mini-Circuits RF FC (Model UFC-6000) and plot Bode Plots at varying Modulation frequencies.
Here are the list of measurements(files attached) taken from FC using SRS(Model DS345) Synthesized Function Generator for a Sinusoidal signal at different Modulation Frequencies ranging from 0.01 Hz to 1 KHz:
Carrier Frequency Modulation Depth Attached measurement Folder
5 MHz Δ f = 5 MHz Bode_5
10 MHz Δ f = 10 MHz Bode_10
20 MHz Δ f = 20 MHz Bode_20
The measured data will be used to estimate:
1) Transfer Function of FC
2) Quantization noise from Power Spectral Density(PSD) vs Hz
To Do Next:
1)Complete interfacing the Pi with EPICS.
2)Make bode plots (Matlab script attached) and PSD plots and estimate the control parameters for optimal design of FOLL PID loop.
