Tescom TC-3000C - TX Output Spectrum - Frequency Range (TRM;CA;04;C)

Appendix B. RF Test Cases of the TC-3000C
218
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 should be enabled (for
Transmitter Test and Loop back Test Modes).
5.2.4 TX Output Spectrum – Frequency range (TRM/CA/04/C)
Goal
Verification if the emissions inside the operating frequency range are within the limits.
Parameters
1. Test mode: Transmitter test, Loop back, Null packets (simple connection).
2. 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.
3. 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:
Data length: 0 (longest supported length)
Number of sweeps: 1
Additional test conditions
In Transmitter test and Loop back test mode the hopping is off, whitening is disabled, 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. 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.
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. If the Test Mode parameter is equal to “Transmitter test” or “Loop back” then the DUT is set
to lowest TX frequency. The tester measures spectrum. The spectrum analyzer settings
are:
