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 (dB). Input level = 100 dB (at
50
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
).
Antenna in/Tuner out
– Yes/Yes
