Frequency A
The ASM card tunes by the L-band frequency rather than the transponder frequency
or local oscillator value. The L-band frequency (950 – 2150 MHz) is the difference
between the downlink transponder frequency and the LNB local oscillator
frequency.
Note: If the values of "Freq" and "LO Off" result in a frequency that is out of the L-
Band, an active error ("Band Freq Error") will be present while the tuning setting is
outside of the L-Band.
1 Use the Up and Down buttons to move the cursor to "Freq," then press the Enter
button.
2 Use the Left and Right buttons to select the column to edit and use the Up and
Down buttons to change the frequency (950 MHz – 14500 MHz), then press the
Enter button to save the selection.
Local Oscillator Offset A
The ASM card offers an offset for the Local Oscillator frequency. This means that the
D9887B receiver will calculate the actual frequency in which the card tunes; saving
the user time and possible miscalculation errors. Follow the steps below to change
the offset or set to zero for manual calculation.
1 Use the Up and Down buttons to move the cursor to "LO Off," then press the
Enter button.
2 Use the Left and Right buttons to select the column to edit and use the Up and
Down buttons to change the Local Oscillator Offset (0 – 12000 MHz), then press
the Enter button to save the selection.
