Instruction Manual
5.8 RF OUT
The unit delivers a fully-modulated QAM rF output. There are two modes that determine the upconversion programming.
NTSC: The NTSC mode permits programming the rF output using a standard NTSC channel number.
Mhz: The Mhz or Frequency Tuning mode permits programming the rF output to the desired frequency.
5.9 Output
In the NTSC Mode it can be upconverted in 6 MHz increments to any NTSC standard channel, 2-135 (center frequency). See
Appendix A for Frequency details.
in the Frequency Mode it can be upconverted to any desired frequency in 12.5 khz increments. Press the (uP) or (DN)
buttons to increment or decrement to the appropriate desired value for each digit, or press and hold the button to scroll.
5.10 QAM Out
The unit has three QAM modes.
NorMAL: The NorMAL QAM mode outputs a QAM modulated signal.
iNVerTeD: The output spectrum is inverted.
oFF: The oFF QAM mode outputs no signal from the module.
Cw: The Cw QAM mode outputs a Cw signal that is useful for measuring the output level of the unit.
(See Appendix A for more detail).
5.11 Output Level
The AQM features electronic output level control.
The output level can be adjusted in any of the QAM modes listed above.
The output level is displayed and measured as an average value. (See Appendix A for more detail).
The output level for a QAM CW is a true representation of a QAM signal level.
The output level range is +30 dBmV to +40 dBmV.
5.12 Bit Rate
This is the actual input date rate that the QAM signal is locked to. This is only displayed in the QAM Out Normal Mode.
5.13 Factory Reset
The unit has a built-in “Factory reset” capability that allows a user to erase all the current programming information for
the AQM and restore it to its factory default setting.
To perform this function, press and hold simultaneously, the eNTeR and
▼
(DN) buttons until the LCD displays “Factory
Reset.” This will cause the unit to reset the programmed information to the factory default settings shown in section 4.3.
