Transmitter Antenna

Transmitter

An enhancement to the integrity (ingress) test system is the function of the receiver

activating the transmitter only when measurements need to be made. Thereby reducing

vehicle power drain, transmitter heating, and general RF pollution. Additionally, the

activation signal from the receiver is encoded and the transmitter recognizes the encoded

activation signal. In this manner, false transmitter activation is eliminated. A multitude of

activation codes is available allowing multiple test systems to be in operation in the same

vicinity. Only the transmitter associated with a given receiver code activates when needed.

In practice the transmitter and activate antennas can be combined into one dual band antenna

with a diplex filter at the transmitter/receiver.

A further enhancement is the coding of the transmitter signal. In this manner, the receiver

can reject measurements not recognized as those from the test transmitter.

Other enhancements include: measurement data storage within the receiver for later retrieval

and analysis, integration with GPS system for location and time data, integration with a

cable modem or wireless device for data transfer to a central CATV location or internet

access.
