Conditions
Measure the YNR addition level at T2 with VIN =
standard color bar signal 1 Vp-p and S30 = off
Measure the YNR addition level at edit mode T2
with VIN = standard color bar signal 1 Vp-p and
S30 = off
Input a standard multiburst signal (1 Vp-p) and
measure the 4 MHz response for 500 kHz at T11
10 MHz response for 500 kHz at T11 when
VIN = standard multiburst signal 1 Vp-p and
S30 = off
1 MHz response for 500 kHz at T2 when VIN =
standard multiburst signal 1 Vp-p and S30 = off
2 MHz response for 500 kHz at T2 when VIN =
standard multiburst signal 1 Vp-p and S30 = off
3 MHz response for 500 kHz at T2 when VIN =
standard multiburst signal 1 Vp-p and S30 = off
3.58 MHz response for 500 kHz at T2 when
VIN = standard multiburst signal 1 Vp-p and
S30 = off
4.2 MHz response for 500 kHz at T2 when
VIN = standard multiburst signal 1 Vp-p and
S30 = off
No input, use VR36 to adjust output frequency to
4 MHz, measure output level
Ratio of 8 MHz component to 4 MHz in the above
state
Measure amplitude of change in output frequency
when 2.6 V DC or 3.1 V DC is applied to T3,
2 x (f3.1 – f2.6)
Measure output frequency when 2.85 V DC
applied to T3, f2.85

Measure amplitude of change in output frequency
when SW35B is from on to off and SW35A is off
Measure amplitude of change in output frequency
when SW35A is on and SW35B is switch from on
to off
VIN = 0.5 mVp-p 10 kHz sine wave
Measure ratio of levels of input and output
amplitude at T4
VIN = 158 mVp-p 2 MHz sine wave
Measure ratio of levels of T4 and T3, difference
with GEMP
VIN = 50 mVp-p 2 MHz sine wave
Measure ratio of levels of T4 and T3, difference
with GEMP
VIN = 15.8 mVp-p 2 MHz sin wave
Measure ratio of levels of T4 and T3, difference
with GEMP
VIN = 15.8 mVp-p 2 MHz sine wave
Measure output amplitude at T4 in edit mode,
difference with GEMP
VIN = 500 mVp-p 2 MHz
Measure ratio of levels of T4 and T3, difference
with GEMP
VIN = 158 mVp-p 2 MHz
Measure ratio of levels of T4 and T3, difference
with GEMP
