"THE WIZARD", MODEL AMMA-1
PRECISION DIGITAL AM MODULATION MONITOR AND ANALYZER
The Wizard is a microprocessor controlled, digital AM modulation monitor/analyzer that precisely measures positive and negative peak modulation, peaks per minute, average peak modulation, modulation density, and more. The Wizard Software (included with The Wizard) and a personal personal computer running DOS enable real-time graphing, logging, and remote operation.
The Wizard features user-defined parameters and settings for maximum flexibility. The two large UP/DOWN menu keys are used to cycle the 16 digit alphanumeric display to the desired menu; the UP/DOWN parameter keys are then used to select the desired setting. The configuration can be saved to non-volatile memory in the unit in the event of a power loss.
A unique "Normal Modulation" indicator allows you to ensure that your modulation is within the parameters that you specify.
An Audio loop-thru permits you to "touch up" your modulation remotely, through the RS-232/RS-422 port.
A built-in Audio Sentry audio failure alarm alerts you to loss of modulation.
The Wizard Software can operate the AMMA-1 remotely and is also used to display real-time graphs. A direct connection or a pair of modems and a phone line may be used. The software is fully password protected with three levels of access.
