5.2.6 TX Output Spectrum – Adjacent channel power (TRM/CA/06/C)
Goal
Verification if the emissions inside the operating frequency range are within the limits.
Parameters
1. Test mode: Transmitter test, Loop back.
Note. The test case cannot be executed in Null packets Test mode.
2. BT channels are the TX frequency channels of the DUT, which are selected to test. The
frequency for each channel is calculated as (2402+ch) MHz, where ch is the frequency
channel. The frequency channel is the value from 0 to 78. Any quantity of the frequency
channels can be selected in the TC-3000C. The list of selected channels must be
separated by “-“. For instance, the record “20-40-60” means that the test case must be
executed for four frequency channels: 20, 40 and 60, that is for the frequencies 2422MHz,
2442MHz and 2462MHz.
3. Data length parameter specifies which length of the packet’s payload will be used for the
test case. If the parameter is equal to 0 then the tester will read LMP features of the DUT
and the longest supported length of a packet will be chosen for the test case.
Note. This parameter is ignored in Null packets test mode.
4. Number of sweeps is the number of sweeps parameter of spectrum analyzer.
If the flag “Use Default” is selected then all of displayed values of parameters are ignored and
the listed above values will be assigned automatically:
Test/Normal mode: Transmitter
BT channels: 3-39-75
Data length: 27 (the longest length of DH1 packet)
Number of sweeps: 1
Additional test conditions
Hopping is off, whitening is disabled and the payload’s bit pattern is PRBS9.
Test Procedure
1. If the DUT is not connected then the tester creates connection via access procedures
(paging and inquiry if necessary).
2. The tester will activate test mode (if the test mode is not activated yet) and will set all
necessary parameters of the test mode depending on the parameters Test Mode, Data
length.
3. The tester checks whether the DUT transmits at maximum power. If not and the DUT
supports power control, then the tester will consecutively send LMP_incr_power_req
requests until the LMP_max_power response would be received from the DUT. The time
delay between two consequential LMP_incr_power_req requests depends on the
Pow.SetTime parameter (to modify the value use: Menu  Configuration  DUT 
More3/5  Pow.SetTime, default value is equal to 1 second).
4. The DUT is set to transmit on the given frequency channel. The transmit frequency is
defined by the index M (f(M)=(2402+ch)MHz). In the same way the measurement
frequency is defined by the index N.
