IF F x

sets the first IF filter to one of the filter index values below:

•

0 - 12.0 MHz

•

1 - bypassed

Examples:

Auto IF filter select enabled

First IF filter (0) 12.0 MHz

Second IF filter (5) 2.0 MHz

IF F 0 Sets the first IF filter to 12.0 MHz

IF 9

Sets the second IF filter to 10.0 MHz

2.1.1.29 Low Density Parity Check

LDPC

The LDPC command displays and controls Forward Error Correction settings.

LDPC [M <m>|A <t>|I <s>]

M <m> - Sets LDPC mode to <m>. LDPC mode is stored and transferred if the (waveform) Mode changes.

where: <m> - LDPC Mode
