hopping is off. The hopping is on in all of another cases.
Test Procedure
1. If the DUT is not connected then the tester creates connection via access procedures
(paging and inquiry if necessary).
2. If the Test Mode parameter is equal to “Transmitter test” or “Loop back” then 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, Packet type and
Measurement method. The LMP_test_control command is used to set the parameters in
the DUT.
3. For the given frequency channel the tester measures average power from the start to end
of a packet (see details in the Output Power (TRM/CA/01/C) test case). If the
Measurement method = 1, the tester measures the average power for all of frequency
channels, described in the BT channels parameter.
4. 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).
5. The tester repeats step 3 until minimum possible output power step of the DUT is reached
(LMP_min_power response is received from the DUT). The tester records the power step
size (difference between two nearest output power measurements) and the power at the
minimum power step. The path losses value is added to the last result. To set the path
losses value use Menu  Configuration  DUT  More1/5  PathLoss.
6. The tester increases DUT's output power one step using LMP_incr_power_req command.
The output power at the given power step is measured and step size is recorded by the
tester.
7. The tester repeats step 6 to the maximum possible output power setting of the DUT. The
tester measures and records the maximum power.
8. If the Measurement method = 0, then the tester repeats steps 3 to 6 for each frequency
channel (see the “BT channels” parameter).
Test Results
Pmin is the minimum average output power of the DUT for given frequency channel,
measured in dBm.
Pmax is the maximum average output power of the DUT for given frequency channel,
measured in dBm. The result has only informative character and is not used to reach a verdict.
Pst_min is the minimum power step size for given frequency channel, measured in dB.
Pst_max is the maximum power step size for given frequency channel, measured in dBm.
To reach a verdict the test results are compared with the limit parameters:
“Upper Limit of the minimum power”
“Upper Limit of maximum power step size”
“Lower Limit of the minimum power step size”
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.
