1. OFDM Settings

P2 Type

Choice: SISO| MISO

Default: SISO

Displays the P2 type.

Bandwidth

Choice: 1.7MHz| 5MHz| 6MHz| 7MHz| 8MHz| 10MHz

Default: 8 MHz

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

PAPR Type

Choice: No PAPR| TR-PAPR

Default: No PAPR

Double-click or use the drop-down menu to select the PAPR type. To allow for processing time, the iteration number of the TR algorithm is 10, which is more effective for a small FFT size.

Guard Interval

Choice: 1/128| 1/32| 1/16| 19/256| 1/8| 19/128| 1/4

Default: 1/128

Double-click or use the drop-down menu to select the guard interval. The available choices are determined by the FFT Size setting.

FFT Size

Choice: 1K| 2K| 4K| 8K| 16K|32K

Default: 32K

Double-click or use the drop-down menu to select the FFT size.

Pilot Pattern

Choice: PP1 to PP8

Default: PP7

Double-click or use the drop-down menu to select the pilot pattern. The available choices are determined by the FFT Size and Guard Interval settings as shown in the table below.

Carrier Mode

Choice: Normal | Extended

Default: Extended

Double-click or use the drop-down menu to select the carrier mode. For an FFT Size from 1k to 4k, only normal mode is available. For an FFT Size above 8k, both normal and extended mode are available.

2. Frame Settings

Data Symbol Number (Ldata)

Range: different settings correspond to different range values.

Default: 59

Set the data OFDM symbol number.

Number of Frames per SuperFrame

Range: 1 to 4

Default: 2

Set the frame number per super frame.

L1 Modulation Type

Choice: BPSK | QPSK | 16QAM | 64QAM

Default: 64QAM

Double-click or use the drop-down menu to select the Layer 1 modulation type.

Network ID

Range: 0 to 65535

Default: 12421

Set the network ID for the DVB-T2 signal.

Cell ID

Range: 0 to 65535

Default: 0

Set the cell ID for the DVB-T2 signal.

T2 System ID

Range: 0 to 65535

Default: 32769

Set the T2 system ID for the DVB-T2 signal.

3. Interface Settings

Input Stream Synchronization

Choice: On| Off

Default: Off

Double-click or use the drop-down menu to enable or disable input stream synchronization.

Stream Mode

Choice: High Efficiency Mode| Normal Mode

Default: High Efficiency Mode

Double-click or use the drop-down menu to select the stream mode.

Null Packet Delete

Choice: On| Off

Default: Off

Currently displays the null packet delete state.

4. MultiPath

Multi-path Channel

Choice: Off | 1 Path | 2 Path | 3 Path | 4 Path

Default: Off

Click on the right side of the cell to open the Multi-path Channel dialog box. Use the dialog box to configure up to 4 static paths. For each path, you can set amplitude attenuation (r), time delay (t [ms]), phase offset (q [rad]), and frequency offset (w [kHz]).
