T14A T14A input burst level measured when output goes off
and compared to standard input level, with VIN = 1 Vp-p
standard color bar signal and chroma signal being
gradually attenuated.

above.
T14A
From killer condition as described above, T14A input
burst level is measured when output goes on with input
chroma level being gradually increased. This is
compared to standard input level.

T14A Input signal: 50% white signal superimposed with
4.4336 MHz 300 mVp-p CW. After checking that T14A
output is on, CW frequency is raised until T14A output
goes off. Frequency then is gradually reduced.
CW frequency when T14A output goes on: f1
T14A Same as above, CW frequency is lowered until T14A
output goes off. Then frequency is gradually raised.
CW frequency when T14A output goes on: f2
T51 300 mVp-p, 15.6 kHz pulse train with 5 µs pulse width
is input. Pulse train frequency is raised until T51 output
waveform is impaired. Then frequency is lowered.
Pulse train frequency when T51 waveform becomes
normal: f1
T51 Same as above, pulse train frequency is lowered until T51
