Interface Configuration and Interpretation
IF Spectrum This can be set to Normal or Inverse, to allow for frequency conversions in the signal chain. Conversions that use difference frequencies invert the spectrum; additive conversions do not.
Channel State Available options are auto, static, dynamic and fast dynamic. Using these options you can match the receiver equalizer to the expected channel conditions. The recommended default setting is auto.
NTSC Rejection Filter
This setting gives you control over the integrated cochannel NTSC reject filter. Options are on, off and auto. The recommended default setting is auto.
Carrier Lock This setting allows you to control the carrier lock range. The Normal setting allows lock over a ±150 kHz range; Wide extends the range to ±500 kHz. The recommended default setting is Normal.
Tuner Phase Noise
Normal and High. This control modifies the carrier loop bandwidth to allow the acquisition of nosiy carriers. Normal mode is recommended for general use.
Signal Detection NTSC (National Television Standards Committee) and VSB (Vestigial Side Band).
Front End Lock If full lock is acquired onto the channel and it is receiving the signal correctly, the Front End Lock (FEL) indicator will light up green. When a signal is present but no lock is achieved, the indicator is red. When no signal is found, the indicator is gray.
