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.
5.2.16 Maximum Input Level (RCV/CA/06/C)
Goal
Verification of the receiver performance
Parameters
1. Hopping mode parameter specifies which hopping sequence will be used for the test.
Allowed values of the parameter are:
1 - single frequency (hopping is off)
5 - reduced hopping sequence
79 - hopping is on
2. BT channels are the RX 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 “0-20-40-60” means that the test case must be executed for
four frequency channels: 0, 20, 40 and 60, that is for the frequencies 2402 MHz, 2422 MHz,
2442 MHz and 2462 MHz. This parameter is meaningful only if the Hopping mode parameter
is equal to 1 (hoping is off)
3. RX power is expected power at the input of the DUT’s receiver, measured in dBm.
4. Number of samples is the minimum number of returned payload bytes from the DUT.
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:
Hopping mode: 1 (Hopping is off)
BT channels: 0-39-78
RX Power: -20 dBm
Number of samples: 200,000 bytes
Additional test conditions
Test mode is Loop back, hopping is off, whitening is disabled, the packet type is DH1, the
payload’s bit pattern is PRBS9.
Test Procedure
1. The tester calculates and sets the TX power to satisfy requirement of expected power at
the input of the DUT’s receiver. The TX power is calculated as P
TX
= P
RX DUT
+ PL, where
P
TX
is the TX power of the tester, P
RX DUT
is the expected power at the input of the DUT’s
receiver and PL is the path losses. To set the path losses value use Menu  Configuration
 DUT  More2/5  PathLoss.
2. If the DUT is not connected then the tester creates connection via access procedures
(paging and inquiry if necessary).
3. The tester will activate test mode (if the test mode is not activated yet) and will set all
necessary parameters of the test mode.
