Subject: successfully use ifr2023 to track the frequncy drift of the beat 

  The drift in the demodulated signal (beat frequency x local oscillator) can be tracked by using ifr2023 and sr560. We successfully set the control loop, but

the detail about how ifr2023 works will be reviewed for clarity. The SR560 is set at gain -100, low pass at f = 10Hz. The power spectrum of the drift can be seen from the attachment.
