MHE PID (Hex)
Requires "Coding > General > M/H State > On".
Sets the MHE PID of MPEG-2 packets that contain ATSC M/H data. The PID is a four-
digit value in hexadecimal format.
Since the packets must be treated separately in the postprocessor, the correct specifi-
cation is essential. The parameter is important for the M/H transmission.
If you set the wrong PID or if the fed-in data stream does not contain an M/H element,
a warning is displayed. An ATSC-M/H receiver cannot lock in on the emitted signal, but
the 8VSB standard can still be received.

RF Watermark
Enables/disables the RF watermark.
The standard ATSC A/110 specifies, that you can overlay the RF signal with a water-
mark. For this purpose, the modulator calculates a specific Kasami sequence from the
TX address and the network ID.
The Kasami sequence modulates BPSK and is added to the payload signal as buried
spread spectrum. Thus, a unique watermark is provided for each transmitter.

TX Address (Hex)
Requires "RF Watermark > On".
Sets the TX address that underlays the RF signal as a watermark.
Remote command:
[:SOURce<hw>]:BB:ATSM:TX:ADDRess

Network ID (Hex)
Requires "RF Watermark > On".
Sets the network ID for the watermark. The network ID is a three-digit value in hexa-
decimal format.
