Walsh Code

Range: 0 to 63

Default: 0

Sets the Walsh Code for the selected channel.

Data

Allows you to select or specify the data for the selected channel. The icon at the right of the entry box opens the ClosedData Source Selection dialog box

The Data Source Selection dialog box allows you to select from Random, PN9, MAC Data, Sync Standard or User Defined Bits.

To select from the following data types, click the desired radio selection:

Random

Provides random signal generator data. If this is the selection, you are returned to the Channel Setup pane.

PN9

Provides a pseudo-random bit sequence containing 511 bits (29-1). When there are not enough bits left in the PN sequence to fill a frame, the software repeats the data sequence. When the maximum length is reached, it truncates any remaining data. If this is the selection, you are returned to the Channel Setup pane.

Sync Standard

provides the configuration of Protocol Revision Level, Minimum Protocol Revision Level, System Identification, Network Identification, Frequency Assignment .

User Defined Bits

Opens the Closeduser data entry area, which lets you customize the transmitted data.

The user data entry area contains buttons to import, export, or clear user data along with the ability to insert PN9 data. Optionally you can manually insert or delete data. To manually insert data, simply place the cursor within the data entry area or highlight existing bits, and insert data. There are three ways to insert data: 

(The key board shortcuts Ctrl+C and Ctrl+V work for user data entry.)

To delete data, simply place the cursor at the desired location within the data or highlight bits, and delete the data. The key board shortcut Ctrl+Z also deletes highlighted data.

The maximum number of bits for the user data entry area is 65,536, which is also the maximum file size.

The expanded area has four buttons that can be used to manipulate data for the channel.

The five buttons in the expanded area are:

Import

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 user data entry area. The software accepts the following file types:

The maximum file size is 65,536 bits. If the imported file is larger than 65,536 bits, the software truncates the bits to conform to the maximum file size.

Export

Saves the current data pattern, showing in the user data entry 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 selected file types:

Clear

Clears all data showing in the user data entry area.

Insert PN9

Inserts a fixed pattern pseudo-random bit sequence containing 511 bits (29-1) into the user data entry area. The software generates this fixed pattern in accordance with the CCITT recommendation O.153. Repeated clicking of this button adds additional PN9 sequences until the software attains the maximum file size of 65,536 bits. The software truncates data in excess of the maximum file size.

To edit the data pattern, insert the cursor at the desired point in the file and click Insert PN9, or enter the information manually using the keyboard keys 1 and 0. The software inserts the data at the cursor position and truncates all data in excess of 65,536 bits.

Channel Coding

Selections: On, Off

Default: Off

This setting is only for the paging channel and sets whether the paging channel uses coded or uncoded data.

On

The channel uses uncoded data.

User Defined Bits

Opens the Closeduser data entry area, which lets you customize the transmitted data.

The user data entry area contains buttons to import, export, or clear user data along with the ability to insert PN9 or PN15 data. Optionally you can manually insert or delete data. To manually insert data, simply place the cursor within the data entry area or highlight existing bits, and insert data. There are three ways to insert data: 

(The key board shortcuts Ctrl+C and Ctrl+V work for user data entry.)

To delete data, simply place the cursor at the desired location within the data or highlight bits, and delete the data. The key board shortcut Ctrl+Z also deletes highlighted data.

The maximum number of bits for the user data entry area is 65,536, which is also the maximum file size.

The expanded area has four buttons that can be used to manipulate data for the channel.

RPC Number of Steps

Range: 1-80

Enter the RPC Number of Steps value when RPC Pattern 'UP/Down' or 'Down/Up' is used.

FPC MODE

Displays Forward Power Control mode.

Frame Offset

Displays Frame Offset.

Graphs

CDP

Shows the Code Domain Power (CDP) graph. This graph shows the position and power level of each channel, relative to the Walsh Code applied. Select the channel setup in the Closedtree view to view the CDP distribution for that carrier.

Click on a Closedchannel in the graph to view the parameter selections for that channel.

Hold the cursor over any individual channel to view a Closedtool tip showing the channel number, type, Walsh Code, rate, and power.

Bit Reverse / Hadamard

Toggles between two code order display formats, Hadamard and Bit Reverse.

Hadamard uses an algorithm that displays each Walsh code in sequence and the composite representation of the traffic channel.

Bit Reverse uses an algorithm that rearranges the location of the bits of data such Closedthe bit in most significant bit (MSB) position is rearranged and placed into the least significant bit (LSB) position and so on until all of the bits are rearranged.

Each channel is also displayed as a bar where the height of the bar is proportionately representative of the channel's power and the width of the bar is proportional to the data rate.

CCDF

Shows the Complimentary Cumulative Distribution Function (CCDF) graph. This graph shows the plot and peak-to-average values for the current carrier. This topic describes the CCDF functionality using the graph in the Channel Setup view.

The CCDF graph displays the probability (in percentage) of the generated carrier's calculated peak-to-average power ratio (measured in dB) meeting or exceeding a certain level. The table to the left of the CCDF plot displays the calculated peak-to-average values for the carrier. For additional information, see Understanding CCDF Curves.

Click Generate or Generate and Download from the main tool bar to generate an I/Q waveform and plot the CCDF graph using the current channel configuration. Any changes to the channel configuration setup do not appear on the graph until you generate the waveform. The status bar at the bottom of the screen shows waveform generation progress.

Each time you adjust parameters and generate a waveform, a plot is added to the Closedgraph. The graph retains your three most recent plots (in shades of gray), allowing you to make comparisons of waveform characteristics.

Use the buttons shown below to plot the Gaussian data, reference data and generated waveform data to the CCDF graph. The graph's initial state shows only the Gaussian curve (blue) until you generate a waveform.

Gaussian

Toggles the view of the band-limited Gaussian noise curve (blue).

Reference

Toggles the view of the reference curve (red). The reference appears as a flat line until you generate a waveform and click the Acquire Ref. button

Acquire Ref.

Sets the current waveform curve to yellow and the reference curve to red. Click the Reference button to view the reference curve.
