Methods of Measurement of the Electromagnetic and Operational Compatibility of UPCS Devices
8.1.2
8.1.3
Access criteria functional test (47CFR15.323(c)(6) option not implemented)
This test is to verify that transmission restarts on a different access channel if the access criteria are not met
again on the old channel, for EUTs that transmit control and signaling channels and that do not use the
provisions of 47CFR15.323(c)(6).
The test procedure is as follows:
a) Use frequency administration commands or out-of-operating-region interference (using the
procedures in 7.2.3) to restrict operation of the EUT to two carriers designated f
1
and f
2
. If the
EUT communications protocol uses TDMA to provide multiple channels per carrier, it may be
necessary for test-result observability to additionally use frequency administration commands or
out-of-operating-region interference to further restrict EUT transmissions to a single timeslot of
the usable timeslots available in the TDMA frame structure. If necessary, the manufacturer shall
supply means by which to synchronize the interference with the timeslot structure of the EUT.
The interference shall be timed so as to occur centered within the timeslot.
b) Activate the EUT. The EUT, if it transmits, must do so on one of the two open channels. Note
the channel used. Apply interference on the channel used by the EUT at the level T
U
+ U
M
or
T
L
+ U
M
as appropriate for EUTs that do or do not meet the requirements for using the upper
threshold. Verify that after the next pause, the next EUT transmission occurs on the other open
channel.
Access criteria functional test (47CFR15.323(c)(6) option implemented)
This test is for EUTs that transmit control and signaling channels and that use the provisions of
47CFR15.323(c)(6), thus to verify that the EUT (if in deferral) waits for a channel to go clear, then
implements a 10 ms to 150 ms holdoff prior to using the channel.
The test procedure is as follows:
a) Use frequency administration commands or out-of-operating-region interference (using the
procedures in 7.2.3) to restrict operation of the EUT to a single carrier designated f
1
. If the EUT
communications protocol uses TDMA to provide multiple channels per carrier, it may be
necessary for test-result observability to additionally use frequency administration commands or
out-of-operating-region interference to further restrict EUT transmissions to a single timeslot of
the usable timeslots available in the TDMA frame structure. If necessary, the manufacturer shall
supply means by which to synchronize the interference with the timeslot structure of the EUT.
The interference shall be timed so as to occur centered within the timeslot.
b) Activate the EUT with no interference present. The EUT must transmit on f
1
. Then apply CW
interference on f
1
. The interference level shall be at T
U
+ U
M
or T
L
+ U
M
as appropriate for EUTs
that do or do not meet the requirements for using the upper threshold. The EUT must stop
transmitting within 30 s.
c) Cancel the interference. Measure the time interval between the end of the interference
transmission and the beginning of transmission by the EUT.
d) Repeat step b) and step c) 100 times. If each of the time intervals measured is equal to or greater
than 10 ms and less than or equal to 150 ms and the measured time intervals vary uniformly
between 10 ms and 150 ms, the EUT passes the test.
