Timeslot (Basic)

To open the Timeslot node, click Timeslot in the tree view. The figure below shows the Timeslot node.

Timeslot Node Buttons

Click to open a window with a list of pre-defined timeslot configurations for GSM/EDGE/EGPRS2-A or EGPRS2-B. To replace the current configuration in the Timeslot node with one of these pre-defined configurations, select the desired configuration and click OK or double-click the desired configuration.

Click to open a drop down menu from which you can:

Timeslot Parameters

Select a timeslot from the list at the top of the window. The parameters that you configure at the bottom of the window apply to the selected timeslot.

Timeslot Number

Displays the number of the selected timeslot. The parameters you set apply to this timeslot.

State

Choice: On | Off

Default: On

Double-click or use the drop-down menu to set the state of the timeslot On or Off.

Power

Range: –70 to 0 dB.

Default: 0 dB

Enter a value to set the timeslot power.

Timeslot Type (GSM/EDGE/EGPRS2-A)

Choice: Normal GMSK Burst | Normal 8PSK Burst | Frequency Correction Burst | Synchronization Burst | Dummy Burst | Access Burst | Custom GMSK Burst | Custom 8PSK Burst | Normal 16QAM Burst | Normal 32QAM Burst | Custom 16QAM Burst | Custom 32QAM Burst

Default: Normal GMSK Burst

Double-click or use the drop-down menu to select the timeslot type.

Timeslot Type (EGPRS2-B)

Choice: HSR QPSK Burst | HSR 16QAM Burst | HSR 32QAM Burst | Custom QPSK Burst | Custom 16QAM Burst | Custom 32QAM Burst

Default: HSR QPSK Burst

Double-click or use the drop-down menu to select the timeslot type.

Modulation

Displays the modulation type (appropriate to GSM/EDGE/EGPRS2). This setting is not editable.

Multislot

Choice: On | Off

Default: Off

Double-click the cell or use the drop-down menu to set the multislot state On or Off . When multislot is on, the power level is maintained between timeslots.

This parameter is not active for symbol bit output.

Data Offset

Range: 0 to 32767

Default: 0 (timeslot 0) to 70 (timeslot 7) for single carrier waveforms.

The default data offset continues to increment by 10 for each successive timeslot in subsequent carriers when a multi-carrier configuration is selected from the Pre-defined Carrier Configurations. (For example, in Carrier 2 the default for timeslot 0 is 80, for timeslot 1 is 90, and so on.) If carriers are added manually, the default data offset for timeslots starts at 0 for every carrier.

Enter a value to set a data offset for the selected timeslot.
