7. Whilst observing the oscilloscope,adjust the deviation and balance potentiometers.V R 521 to
obtain a good square at the following deviation:
12.5K Hz channel spacing<=2.5K Hz dev
25K Hz channel spacing<=5K Hz dev
8. It may be necessary to alternate the adjustment of the two potentiometers.
9. S weep the signal generator between 100Hz and 3K Hz.R ecord the peak deviation. The peak
deviation should be as above.If necessary adjust the potentiometers to achieve this.
