Sync Separator with AFC LVA519

* AFC output delay time (td)

Set SW1 at A and adjust TP5 output to 15.73kHz. Then set SW1 to B

and measure td from TP2 and TP5 waveforms. (specified at 50% of

sync signal amplitude)

* AFC output pulse width (Pw)

Set SW1 at A and adjust TP5 output to 15.73kHz. Then set SW1 to B

and measure Pw from TP5 waveform. (specified at 50% of sync

signal amplitude)

* Schmidt trigger threshold

(VthH) (VthL)

Measure VthH and VthL at TP3 and TP4.
