Carrier ATSC

1. Basic

State

Double-click or use the drop-down menu to control the operating state of the carrier.

Format

The format of the carrier.

Frequency Offset

Range: -40.0 to 40.0 MHz

Set the frequency offset for the carrier relative to the signal generator’s frequency setting.

The valid range will be different for every format with various over-sampling ratio.

Initial Phase

Range: 0 to 359 degrees

Set the initial phase of the carrier.

Power

Range: -50 to 0 dB

Set the carrier’s power relative to the signal generator’s amplitude setting.

2. ATSC Settings

Number of Frames

Range:1 to 5000

Default: 1

Set the number of ATSC Data frames.

Modulation Type

Choice: 8VSB | 16VSB

Default: 8VSB

Double-click or use the drop-down menu to select the modulation type of ATSC.

Pre-Coder

Choice: ON | OFF

Default: ON

Double-click or use the drop-down menu to enable or disable the Pre-Coder.

This entry is only available when modulation type is 8VSB.

RS Encoder

Choice: ON | OFF

Default: ON

Double-click or use the drop-down menu to enable or disable the RS encoder. For ATSC, when the RS encoder is off, the payload is treated as the output of a RS encoder and fed into the convolutional interleaver directly.

Filter Type

Choice: Root Nyquist | Nyquist

Default: Root Nyquist

Double-click or use the drop-down menu to select the filter type of ATSC.

Roll-off Factor

Range: 0 to 1

Default: 0.1152

Set the roll-off factor of ATSC.

Multi-path Channel

Default: OFF

To enable static multi-path channel.

Click on in the right side of the cell, and Multi-path Channel configuration window will pop up.

3. Data Source Settings

Useful Bit Rate

The useful bit rate. The bit rate can be transmitted by current encoding, modulation and framing configurations.

Supported File Size

The maximum file size supported by 64MSa memory of MXG/EXG/ESG/PSG.

Payload

Data Source Type

Choice:

Normal: Test Pattern | Demo File | TS File | TS File Wizard

When RS Encoder is off: Test Pattern | TS File

For DVB-H: Test Pattern | TS File

For one-seg ISDB-T: Test Pattern | TS File | TS File Wizard

Default: Test Pattern

Double-click or use the drop-down menu to select which type to be used as the data source.

If TS File" is selected, "File Name" is required; If "TS File Wizard" is selected, "File Wizard" is available.

Learn more about the different Data Source Types, refer to the page Data Source Type.

Pattern Bits

The data bits used as test pattern.

Click the right button to open "Test Pattern Edit" dialog and select test pattern to use.

SYNC Insertion

Choice: True | False

Default: False

Double-click or use the drop-down menu to determine whether a SYNC byte (0x47) should be inserted into the test pattern.
