The TVMA-1, TV Wizard is a micro-processor controlled, digital baseband TV modulation monitor/analyzer that precisely measures peak modulation, peaks per minute, average peak modulation, modulation density, and more. The Wizard can operate with an existing TV modulation monitor, or it can accept 4.5 Mhz from a good TV visual demod. The Wizard Software (included with The Wizard) and an IBM compatible personal computer enable real-time graphing, logging, and remote operation through the RS-232 port.

The TV 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 built-in Audio Sentry audio failure alarm alerts you to loss of modulation.

SOFTWARE
The Wizard Software allows the Wizard to be accessed and controlled remotely using either a direct RS-232 connection, or a pair of modems and a dial-up telephone circuit. The front panels of the Wizard and all associated units may be simultaneously displayed and independently controlled on the PC screen. In the graphing mode, a moving window in time shows modulation levels over the preceding adjustable time window. Peak, average, minimum, and density of modulation may all be displayed in the time windows, with the readings scrolling across the PC screen, as well as in color bar-graphs. Modulation histograms, calculated using either a sliding or an infinite-length window, are also available. All collected data may be logged to disk for future reference and comparison. The Wizard software is fully password protected with three levels of security.
