Subject: Characterization of UFC-6000 RF Frequency Counter 


To characterize the Mini-Circuits RF FC (Model UFC-6000) and plot Bode Plots at varying Modulation frequencies.

Work Done:

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.
