4,5.2.25 Transmitting current test.
resistive load from the ANTENNA to the RCU case. press the DESTRUCT
key, then press the XMIT switch.' Measure the current into Pi-RED and
verify compliance with the requirements of 3.6.5.
With the supply set to 13 +
Transmitting Power test.
4.5.2.26
0.1 volts, press the DESTRUCT key then press the XMIT key. Measure the
power into the resistive load and verify compliance with the
requirements of 3.6.6.
4.5.2.27 Tuning (load
matching) capability test.
With each of
the
complex loads of 3.6.7, perform the following: connect the load
the ANTENNA to the RCU case; press the DESTRUCT key, then press
from
the
XMIT switch; measure the power into the SO ohm real component of
.
the
load and verify compliance with the requirements of 3.6.7.
cutoff test. Reduce the supply voltage at
4.5.2.28 Transmitter
Pi-RED to 10.55 + 0.05 volts. Press the DESTRUCT key and then press
.
the XMIT key. Verify transmission responses with the requirements of
3.6.8. Reduce the supply voltage to 9.45 + 0.05 volts. Press the
DESTRUCT key and then press the XMIT key. Verify transmission
response with the requirements of 3.6.8. Set the supply voltatge to 13
+ 0.5 volts.
4.5.2.29 Data retention test. "Turn the unit power switch off.
Turn the unit power switch on and key in "12345" in the next 15
seconds. Press the COPY key then press the TRANSFER key. Note the RCD
code, Turn the unit power switch off. Disconnect the positive SUpPly
terminal from Pi-RED. Wait 315 + 15 seconds. Reconnect the positive
supply terminal to Pi-RED. Turn the unit power switch on and key in
the correct STORE code in the next 15 seconds. Repeat the RCD transfer
test of 4.5.2.12. Verify that the RCD code is the same as noted just
before disconnecting the batteries. Turn the unit power switch off
then on. Key i n the correct SEND code in the next 15 seconds. Step
thru each group using the GROUP ID key. Verify that each group status
has retained the status just before disconnecting the battery in
compliance with the requirement of 3.6.9.
4.5.3 High
temperature test. Conduct the RCU performance tests
described in the paragraphs 4.5.2 - 4.5.2.29 with the unit under test
temperature stabilized at 145 (+5/-0) degrees F in compliance with
requirement 3.10.
4.5.4 Low temperature test. Conduct the tests listed in 4.5.3
with the unit under test temperature stabilized at -35 (+0/-5) degrees
F in compliance with requirement 3.11.
4.5.5 Tuning Electronic Components Assembly Performance test.
This section describes the performance tests for the Tuning Electronic
Equipment Components Assembly (Tuner), assembly number 9333578.
Unless otherwise specified, all testing shall be sequentially
performed in the order listed at room ambient conditions. Unless
otherwise specified, all test setup shall be retained throughout
.
subsequent
tests.
