Auto TFC (MB-OFDM)

Menu Path: MeasSetup > MB-OFDM Demod Properties > Format tab

Default: Selected (See MB-OFDM Standard Setups/Presets Table.)

Range: 1 to 10

The Auto TFC checkbox, when selected, automatically sets the Time Frequency Code from the Sync sequence. The Time Frequency Code parameter chooses a Time Frequency Code (TFC Transport Format Combination) from 1 to 10 specific to your signal under test.  

The Auto TFC selection in the Preset to Standard automatically selects this checkbox and a manual TFC selection in the Preset to Standard clears the checkbox.

Band symbols are transmitted in a six-symbol sequence that is determined by the TFC. The Table below shows the six-symbol sequences for Band 1 and each TFC 1 to 10. To learn more about the TFCs, see the Time-Frequency Code topic in the Overview section.
