Frequency Response Configuration
In the television demodulator system there are two levels of frequency
response adjustment. The first is factory set and cannot be adjusted
from the front panel. The second is the manual frequency response
item which allows minor adjustments to the frequency response.
Use caution when changing the manual frequency response and do so
only when connected to equipment that can measure the changes to
frequency response.
The changes to frequency response affect only the current active
frequency, which is shown on the top line of the frequency response
configuration display. You can adjust several frequencies which are
stored in the television demodulator non-volatile memory.
Due to memory limitations within the television demodulator, it is
impractical to store frequency response adjustments for every possible
frequency, so the adjustments are possible only for the range of
frequencies listed in Table 3–2.
