Methods of Measurement of the Electromagnetic and Operational Compatibility of UPCS Devices
The test described as follows is intended to verify that the EUT makes its channel selection decision on the
basis of a recent power level reading:
a) Allow EUT transmission on only two carrier frequencies, which will be designated f
1
and f
2
.
This limitation to carriers f
1
and f
2
is performed preferably by administration commands for the
EUT, or alternatively by applying by a multicarrier interference generator uniform interference
on all system carriers except f
1
and f
2
, at a level of T
U
+ U
M
, in-band per carrier. Set the
interference level to the EUT on f
1
to a level of T
U
+ U
M
, and let there be no interference applied
on f
2
.
b) Initiate transmission and verify that the EUT transmits on f
2
. If a connection was made,
terminate it.
c) Apply interference on f
2
at a level of T
U
+ U
M
, in-band, and immediately remove all interference
from f
1
and immediately (but not sooner than 20 ms after the interference on f
2
is applied) cause
the EUT to attempt transmission. The EUT should now transmit on f
1
, if it transmits.
d) If the EUT transmits on f
2
, it fails.
7.4
7.4.1
Threshold monitoring bandwidth
If the monitoring is made through the radio receiver used by the EUT for communication, the intended
bandwidth requirement on the monitoring system is met. The manufacturer shall declare and provide proper
evidence that the monitoring is made through the radio receiver used for communication.
If a dedicated monitoring receiver is used, monitoring bandwidth tests are required. See the test procedures
in 7.4.1 and 7.4.2.
Using either frequency administration commands or out-of-operating-region interference (using the
procedures in 7.2.3), restrict operation of the EUT to a single carrier frequency f
1
, and verify that the EUT
can establish a connection.
When a companion device is required, see 7.3 for set-up guidance.
Simple compliance test
This test may be used to verify that the EUT complies with the rules. While it verifies compliance using a
simple test, failure does not indicate that the EUT fails to comply with the rules. If this test fails, the more
complex test of 7.4.2 may be used to demonstrate conformance to the requirements of 47CFR15.
Using either frequency administration commands or out-of-operating-region interference (using the
procedures in 7.2.3), restrict operation of the EUT to a single carrier frequency f
1
, and verify that the EUT
can establish a connection with no interference applied on f
1
. Turn on the interfering signal centered at a
frequency above the center of the emission of the EUT separated by 30% of the emission bandwidth of the
EUT and with a level 10 dB + U
M
above T
U
or T
L
, as appropriate for EUTs that do or do not meet the
requirements for using the upper threshold.
19
The bandwidth of the interfering signal must be equal to or
greater than B
limitL
. Verify that the EUT will not transmit. Repeat with the interference centered at a
frequency below the center of the emission of the EUT separated by 30% of the emission bandwidth of the
EUT and with a level 10 dB + U
M
above T
U
or T
L
as appropriate for EUTs that do or do not meet the
requirements for using the upper threshold. Verify that the EUT will not transmit.
19
The calculated upper threshold limit shall be used if the EUT system has more than 40 channels and implements the LIC. Otherwise,
the calculated lower threshold limit shall be used.
