4.4.3.2 Method of Measurement
1. Connect the access network to the access terminal antenna connector as shown in Figure
12
8.5.1-4. The AWGN generator and the CW generator are not applicable in this test. Connect a
13
spectrum analyzer to the access terminal antenna connector.
14
2. For an access terminal that supports Subtype 3 physical layer and two or more reverse CDMA
15
channels, configure the access terminal to transmit on the two carriers at the maximum
16
possible frequency separation (MaxReverseLinkBandwidth 1) between them.
17
3. Set up a Test Application session for Subtype 3 Physical Layer. Configure the Test Application
18
RETAP so that the Reverse Data Channel payload size corresponds to 256 bits with
19
Termination Target of 4 sub-packets for each of the channels. Configure the Test Application
20
FETAP (for Subtype 3 Physical Layer) so that the Forward Traffic Channel data rate
21
corresponds to the 2-slot version of 307.2 kbps, and the ACK Channel is transmitted at all the
22
slots for each of the channels. Set RAB to ‘0’ at all times for each of the channels.
23
4. Set Îor to –105.5 dBm/1.23 MHz for each of the channels.
24
5. Send continuously ‘0’ power control bits to the access terminal on each of the channels.
25
6. Set the resolution bandwidth of the spectrum analyzer to 30 KHz. The value of the occupied
26
bandwidth is calculated by an external or internal computer by summing all samples stored as
27
“total power”.
1 The maximum separation between the highest and lowest reverse link CDMA channels within a Band Class that
can be assigned to the access terminal in units of 2.5 kHz. See Table 7.9.7.1-1 in C.S0024-B v-2.0 for more
details

7. Measure the occupied bandwidth for each carrier.

8. For an access terminal that supports Subtype 3 physical layer and two or more reverse link
3
channels, configure the access terminal to transmit on two adjacent reverse CDMA channels at
4
a spacing of 1.23 MHz for BC 0 Subclass 2 and 3, 1.25 MHz for BC 3 and 6 between the center
5
frequencies.

9. Repeat steps 3 through 6 for setup 8 and measure the occupied bandwidth for two adjacent
carriers
10. For an access terminal that supports Subtype 3 physical layer and three or more reverse link
channels, configure the access terminal to transmit on three adjacent reverse CDMA channels
10
at a spacing of 1.23 MHz for BC 0 Subclass 2 and 3 or 1.25 MHz for BC 3 and 6 between the
11
center frequencies.
12
11. Repeat steps 3 through 6 for setup 10 and measure the occupied bandwidth.
13
12. For an access terminal that supports Subtype 3 physical layer and three or more reverse link
14
channels, configure the access terminal to transmit on the two carriers at the maximum
15
possible frequency separation (MaxReverseLinkBandwidth) between them, and also transmit
16
third carrier between two carriers. The third carrier shall be an adjacent carrier of rightmost or
17
leftmost carrier. This test is only performed the MaxReverseLinkBandwith can support this
18
transmission mode.
19
20
13. Repeat step 3 through 6 for step 11. The occupied bandwidth shall be measured for isolated
carrier and two adjacent carriers independently.
21
14. For an access terminal that supports Subtype 3 physical layer and three or more reverse link
22
channels, configure the access terminal to transmit on the two carriers at the maximum
23
possible frequency separation (MaxReverseLinkBandwidth) between them, and also transmit
24
third carrier between two carriers. The third carrier shall not be an adjacent carrier of
25
rightmost or leftmost carrier. The channel spacing shall be multiple of 1.23 MHz for BC 0
26
Subclass 2 and 3 or 1.25 MHz for BC 3 and 6. This test is only performed the
27
MaxReverseLinkBandwith can support this transmission mode.
28
29
15. Repeat step 3 through 6 for step 14. The occupied bandwidth shall be measured for each
isolated carrier.

4.4.3.3 Minimum Standard
2
In the multiple carrier transmission, the occupied bandwidth for each carrier still remains within 1.48
3
MHz. Based on this assumption, the following minimum standards are defined.
4
5
The occupied bandwidth for multicarrier transmission shall not exceed values defined in table x and
6
table y. If the carriers are not adjacent, or only partially adjacent, the occupied bandwidth of each
7
carrier or partially adjacent carriers shall not exceed values defined in table x and table y.
