DPCCH Transmission Pattern Selection for Advanced UL

Use this dialog box to select a Continuous power level for all slots or with the user-defined selection, configure a customized data bursting pattern for up to 15,330 slots.

Descriptions

This list enables you to quickly access the different areas of the Transmission Pattern Selection dialog box.

Continuous User Defined Burst Pattern Import Export

Clear Transmission Pattern Tool

Continuous

The signal source transmits the data at the power level set in the Power cell.

User Defined Burst Pattern

This selection enables the dialog box editor and allows the user to customize a data bursting pattern for each slot within a frame for up to 1022 frames.

Import

This button loads a user-defined pattern from a selected location. When you select this button, the Open user defined data dialog box appears for navigating to and selecting the desired file. An imported file automatically updates the Transmission Pattern area. The software accepts the following file types:

• ASCII text

• comma separated values (csv)

To create a file, enter four values per slot: frame number, slot number, power level, and state (0 or 1):

For example, to set slots 0 and 3 for frame 0, and slots 2 and 5 for frame 2, use the following format:

0,0,-10 dBm,1,0,3,-5 dB,1,2,2,1 dB,1,2,5,5 dB,1

The power unit, and the space between the power value and dB is not required. If desired, place each slot setting on a separate line:

0,0,-10,1,

0,3,-5,1,

2,2,1,1,

2,5,5,1

The maximum file size should not exceed the data required to set the maximum number of slots (15,330) and the number of configured slots cannot exceed the waveform length.

Export

This button saves the current burst pattern, showing in the Transmission Pattern area, to a file. When you select this button, a Save user defined data dialog box appears for navigating to the location where you can save the file. The software saves the user data as one of the following user-selectable file types:

• ASCII text

• comma separated values (csv)

Clear

This button clears the Transmission Pattern table of all entries and resets the Power column to 0.00 dB for all slots..

Transmission Pattern

Use this table to manually set the state (on = checked) and power level for each slot.

Frame

Displays the frame number (0–1021). The frame number increments after every 15 slots.

Slot

Displays the slot number (0–14) for each frame. The slot numbers repeat after every 15 slots. The software supports a maximum of 15,330 slots, and the number of configured slots cannot exceed the waveform length.

State

Manually set the state to either on (checked) or off for each slot. When left unchecked (off), the slot is DTX.

Power

Range: -60 to 20 dB

Manually set the power level for each slot. The bursting pattern uses the RMS of the carrier power as the absolute burst amplitude. During the power search the signal source uses the highest amplitudes of the channels (slot power + channel power) to find the RMS value. When you download the waveform, the software initiates an instrument power search. 

Tool

Use this table to set up and apply a repeating bursting pattern for a single power level.

Tool Descriptions
Start Step Repeat	Power Apply Pattern

Start

Range: 0 to 15329

Set the starting slot number offset. While the Transmission Pattern table slot numbers (0–14) repeat for each frame, the Start values continuously increments up to the maximum range value. For example, to start the pattern on frame 2, slot 10, set this cell's value to 40. To set slot 5 in frame 8, set the Start value to 125.

Step

Range: 0 to 15329

This cell sets the pattern of transmitted slots by setting the interval of active slots. For example with a value of two, the software sets a repeating pattern for every other slot starting with the slot identified in the Start cell and ending with the number of repetitions identified in the Repeat cell. The software supports a maximum of 15,330 slots, and the number of configured slots cannot exceed the waveform length.

0	The pattern consists of only the slot identified with the starting value and ignores the repeat value
1...15329	The value determines whether the pattern transmits all slots from the Start value to the Repeat value or includes an integer number of DTX slots between each transmitted slot: 1—transmits all slots from the Start value to the Repeat value 2...15329—includes DTX slots

Repeat

Range: 0 to 15330

Sets the end slot number for the pattern.

0	No slots are set.
1...15330	The value determines the number of configured slots. 1—sets only the slot identified by the Start value. 2...15330—sets the number of slots

If this value is larger than the number of remaining slots from the Start value to the last slot, then all remaining slots are included in the pattern. The number of configured slots cannot exceed the waveform length. 

Power

Range: -60 to 20 dB

Sets the power level for the slots in the pattern. If needed and after applying the pattern, manually adjust the power level on individual checked slots. The bursting pattern uses the RMS of the carrier power as the absolute burst amplitude. During the power search the signal source uses the highest amplitudes of the channels (slot power + channel power) to find the RMS value. When you download the waveform, the software initiates an instrument power search. 

Apply Pattern (Button)

Applies the repetition pattern to the Transmission Pattern table.
