– Audio modulation factor, temperature stability ±12%

– Audio carrier, temperature stability ±15 kHz

– Video output level temperature stability 66 ±3 dB

– Audio output level difference 50 ±4 dB

– Synchronous level, temperature stability

V/S = 7 ±0.5/3 ±0.5

– Differential gain, temperature stability 15% (MAX.)

– Differential phase, temperature stability 15° (MAX.)

• Overall picture and total quality

– Operation shall be problem-free. This paragraph is

subject to sensory tests; therefore, any discrepan-

cy arising between the parties concerned regarding

final judgment shall be settled by mutual consent.

(Limit standards shall be specified as needed.)

• Power source

– Input voltage 5 VDC ±0.2 +B (MOD)

– Allowable ripple voltage: 50 mVp-p MAX.

– Current consumption 30 mA (MAX.), 20 mA (TYP.)

Booster

• Insertion loss – ANT IN → TV OUT 6.5 dB (MAX.)

– Measure at 55 MHz to 890 MHz

• Distribution loss –ANT IN → TUN OUT 6 dB (MAX.)

– Measure at 55 MHz to 890 MHz

• Isolation 60 dB (MIN.), fs, fp

• VSWR, measure at 55 MHz to 890 MHz

– ANT IN 4 (MAX.)

– TUN OUT 3 (MAX.)

– TV OUT

– MOD OFF 4 (MAX.)

– MOD ON 3 (MAX.) fs, fp

• Cross Modulation (dBµ). Input level = 100 dBµ (at

50 Ω terminal)

– f1 = 183 MHz, f2 = 189 MHz, f(IM) = 177 MHz

– 55 (MIN.)

– f1 = 183 MHz, f2 = 189 MHz, f(IM) = 195 MHz

– 55 (MIN.)

• Switching operation

– ANT IN → TV OUT

– Ground +B terminal

– MOD OUT → TV OUT

– When +5 V is applied across +B terminal

Durability Test

• Vibration test

– Apply vibration of 2 mm full amplitude, 1,500

times/minute from three directions for 15 minutes

each: there shall be no looseness, etc., and all

performance requirements shall be satisfied.

• Impact test

– Apply a 70 G impact using an impact tester; no

damaged parts or looseness shall be observed,

and performance shall not be remarkably affected.

• Moisture resistance

– Test samples shall be left in an environment with

temperature at 40°C ±5°C and relative humidity at

90 +0, -3%, for 500 hours, then left at normal tem-

perature and humidity for 40 minutes. The unit

shall then operate normally without malfunction.

• High temperature resistance

– Test samples shall be left in a 70°C ±2°C bath for

500 hours, then at normal temperature and hu-

midity for 40 minutes. The unit shall then operate

normally without malfunction.

• Low temperature resistance

– Test samples shall be left in a -20°C ±2°C bath

for 500 hours, then at normal temperature and

humidity for 40 minutes. The unit shall then oper-

ate normally without malfunction.

• Thermal shock resistance

– 10 test cycles shall be conducted under the fol-

lowing conditions (see Figure 2) and test samples

shall then be placed in a normal temperature and

humidity atmosphere, cleared of excess water,

left for 40 minutes. Subsequent operation shall be

trouble-free.

Operating Conditions

• Operating guarantee conditions

– Operation shall be trouble-free under ±0°C to

60°C and 85% RH MAX.

• Storage conditions

– Temperature -10°C to 70°C

– Humidity 90% RH (MAX.)

Electrostatic Test

• Electrostatic test (15 kV (+) and (–) polarities, 10

times each) shall be conducted on ANT IN and TV

OUT terminals. Subsequent operation shall be trou-

ble-free (C = 200 pF, R = 500 Ω).
