AQM - Agile QAM Modulator Main Interactive Sequence The main interactive sequence is where all the core module programming is performed. This sequence is accessed anytime a user depresses one of the t (L) or u (R) and ▲ (UP) ▼ (DN) arrow navigation keys. The following diagram depicts the LCD screens available in the main interactive sequence. Note: Factory Reset Default values depicted in illustration. 21
AQM - Agile QAM Modulator Programming a Variable 1. When a user arrives at a screen whose variable needs to be changed, the user depresses the ENTER button until the blinking cursor is displayed. 2. After the blinking cursor is displayed the user simply presses the ▲ (UP) or ▼ (DN) arrow buttons to increment or decrement to the appropriate desired value. 3. When the user reaches the desired setting the ENTER button is pressed again to save the change, then the corresponding AQM module stores the new information. Interactive Sequence Detail QAM Mode The AQM can be set to comply with the ITU-TJ-83 Annex A & Annex B specifications. ITU-A - is used for DVB operation ITU-B - is used for DigiCiper II operation Encoder The Encoder selection is only used in ITU-A Mode. If set to ITU-B Mode, then the Encoder shows NONE. QAM The QAM modulation type is user selectable. If the unit is set to ITU-B Mode, then only QAM 64 or 256 are available. Alpha The Alpha setting is used to set the roll-off factor. Settings are typical depending on the Operation Mode. The standard settings are as follows: ITU-A - 15% ITU-B - 18% 22
