BGP1 Burst gate pulse timing 1
BGP2 Burst gate pulse timing 2, BGPW Burst gate pulse width
FH Horizontal free running frequency
Measure the output frequency at pin 10 when no signal is input .
FPH1 Horizontal pull-in range 1
FPH2 Horizontal pull-in range 2
Change the frequency of SGc and measure the frequency at the
moment when the output signal at pin 10 and the input signal at pin
42 are pulled in. The horizontal pull-in range is measured by
comparing with 15.734kHz.
HPT1 Horizontal pulse timing 1
HPT2 Horizontal pulse timing 2
HPT3 Horizontal pulse timing 3
HPT2 = Hphase data ( 0 ) - HPT1
HPT3 = Hphase data (15) - HPT1
TH Horizontal pulse width, VH Horizontal pulse amplitude
HSTO Horizontal pulse stop function
Confirm that the horizontal output is high when the horizontal stop
switch is on.
AFCG AFC gain
1. Measure AFC on which is the output amplitude of pin 12 when
AFC switch is on and AFC off which is that when the switch is off.
2. AFCG is defined as follows:
FV Vertical free running frequency
Measure the output frequency at pin 14 when no signal is input.
SW Service SW operation
Measure the output DC voltage at pin 14 when the service switch is
on.
FPV Vertical pull-in range
Decrease the frequency of SGd and measure the frequency when
output waveform at pin 14 is pulled in.
VW Vertical pulse width (free running)
VBLKW Vertical blanking width
WVSS Vertical sync.detection minimum width
Change the input pulse width of SGd and measure the input pulse
width at the moment when the output signal at pin 14 is pulled in.
FBPI FBP inv OUT
Measure the Hi and Lo voltages of the pin 13 output pulse.
