Note:
1)
The RXFREQ parameter in the “FREQ” sub-menu specifies the off-air receiver channel frequency for
the internal tuner to receive the proper over-the-air UHF channel. This setting is used when the unit is
configured to operate as a Translator (“INPUT” set to TUNER) and is ignored when the unit is
configured to operate as an Exciter (“INPUT” set to TS).
2)
The TXFREQ parameter in the “FREQ” sub-menu specifies the channel frequency for the modulated
RF output signal of the exciter/translator.
3)
The "Hz" parameter provides a direct adjustment (offset) of the frequency of the TXFREQ RF output
signal. The range is -50,000 Hz to +50,000 Hz, with steps of 1 Hz. This feature is designed for up to
50 kHz spectrum shift as ATSC standard required, or adjustment of the output frequency for carrier
accuracy.

Note:
1)
The MODE sub-menu provides settings for the modulation mode selected. The ACT-5X
Exciter/Translator operates in ATSC Legacy (A/53) mode and as such always displays 8VSB under the
MODE menu. There is an optional ACT-5X series platform that operates as an ATSC MH Translator,
which presents additional parameters under this MODE sub-menu for MH (A/153) configuration.
