Influx current measured at pin 41 in power save mode
Sum of influx current at pins 36, 41, 47, 76 measured;
5V: pins 36, 41, 47; 7V: pin 76
T38 output level measured with
VIN = 1.0 Vp-p video signal (PAL)
T38 output level measured with
VIN = 1.0 Vp-p video signal (NTSC)
Ratio of VEE and T38 output level with
VIN = 2.0 Vp-p video signal
Ratio of VEE and T38 output level with
VIN = 0.5 Vp-p video signal
T38 SYNC level measured with
VIN = 700 mVp-pLUMI, 600 mVp-p SYNC
T38 SYNC level measured with
VIN = 700 mVp-pLUMI, 150 mVp-p SYNC
T37 output pulse crest value measured with
VIN = 1.0 Vp-p video signal
T37 output pulse width measured with
VIN = 1.0 Vp-p video signal
Delay of output SYNC vs. input SYNC measured with
VIN = 1.0 Vp-p video signal
Input level gradually attenuated and measured when
output pulse width becomes larger than PWSYR by 1 µs
Potential measured with VIN = 1.0 Vp-p video signal,
under following conditions.
T38 sync tip level: LSYN
Pedestal level: LPED
White peak level: LWHT
T38 DC level measured with 2.7V DC applied to T33.
Using this as LHDR, differential to LPED (see above) is
calculated.
T38 DC level measured with 1.3V DC applied to T33.
Using this as LWHR, differential to LWHT (see above) is
calculated.

VIP = 1 Vp-p standard color bar signal
input
1 MHz response of T25 vs. 500 kHz with VIN = 1 Vp-p
standard multiburst signal
2 MHz response of T25 vs. 500 kHz with VIN = 1 Vp-p
standard multiburst signal
3 MHz response of T25 vs. 500 kHz with VIN = 1 Vp-p
standard multiburst signal
