Test Mode Operating Mode
Expected Burst
This parameter is only used when the test set’s operating mode is set to Test Mode or when the Cell Activated
state is set to Off. (If it is not set, the test set may not synchronize to the input signal’s midamble.) When
operating mode is set to Active Cell and the Cell Activated state is set to On, the test set automatically selects
the correct burst type.
A TCH can have one of eight midamble patterns. These patterns are called Training Sequence Codes (TSC).
The Expected Burst parameter allows you to set the test set to expect a certain midamble pattern (TSC0
through TSC7) from the mobile. Alternatively, selecting RACH for this parameter allows you to set the test set
to expect the special midamble pattern used by a RACH burst.
For details on the GPIB command see
. (If you are using the test set manually, the
Expected Burst field is in the Call Parms window, screen 3 of 3, F12.)
OUTPUT 714;”CALL:BURST:TYPE TSC5” !Sets the test set to expect a TCH with midamble
!pattern TSC5.
BCH Test Function Behavior
• The test set generates a BCH without a TCH. BCH configuration and timeslot configuration are the same
as when the operating mode is set to active cell.
command.
• By default, the test set expects the mobile station to transmit on the uplink BCH. The test set’s receiver
frequency can be set manually, which de-couples the automatic setting.
• Changes to the MS TX level will couple to the expected power, and the MS TX Level parameter will be
transmitted on the downlink BCCH.
• All measurements are available to the user, the same as if the operating mode was set to active mode.
