5. Tester sets N := 0.
6. Tester sets j := 0.
7. The tester measures spectrum. The spectrum analyzer settings are:
- Spectrum measurement method: FFT
- Center frequency: f(N)
- Span: 2.5 MHz
- Resolution Bandwidth: 10 kHz
- Trigger: start time of the RX slot
- Detector: Average
- Mode: Maxhold
- Trigger: start time of the tester’s RX slot
- Sweeptime: tester’s RX slot
- Number of sweeps: 1
Tester integrates the spectrum data from f(N)-500KHz to f(N)+500KHz for each 100KHz
bandwidth and each calculated power is recorded as P
ij
.
8. Tester increments j and repeats step 7 until j < Number of sweeps.
9. For each i the tester searches maximum value of the power within sweeps: P
maxi
= max(P
ij
).
10. Tester calculates and records the power of N channel: P(N)=

value is added to the result. To set the path losses value, use
11. Tester increments N and repeats step 6 to 10 for 79 channels, N=
78,0
.
12. Steps 4 to 11 are repeated for each specified TX frequency channels of the DUT (see the
“BT channels” parameter).
Test Results
M is the number of the TX frequency channels of the DUT
P(N) is the power, measured in dBm, in the N
th
adjacent channel for given TX frequency
channels of the DUT
To reach a verdict the test results are compared with the limit parameters:
“Upper Limit of the power in a channel M-N=2” (in dBm)
“Upper Limit of the power in a channel M-N>=3” (in dBm)
“Max. number of excepted channels”
“Upper Limit of the power in excepted channels” (in dBm)
To change the parameters, use the Edit menu of the test case. If the flag “Use Default” is
selected then all of displayed values of parameters are ignored and the values according to RF
Test Specification [1] are assigned automatically.
Requirement to Initial Condition of a DUT
If the DUT can be controlled through HCI, the DUT must be connected to an appropriate HCI
port of the tester and correct value of the HCI Port parameter must be specified in DUT
configuration (Menu  Configuration  DUT  More1/5  HCIPort).
If the DUT does not have HCI then the DUT must be in the Inquiry Scan/Page Scan state
(maximum activity of the scan mode is desirable) and Test Mode must be enabled.
