Abstract
A real time apparatus for testing a DTV antenna transmitting system, wherein the DTV antenna transmitting system transmits an original signal from a DTV transmitter to a DTV transmitting antenna, is disclosed that includes a probe, wherein the probe is connected in series with the DTV antenna transmitting system, and senses signals traversing the DTV antenna transmitting system. An error detector of the testing apparatus compares the received signal to the original signal to identify the magnitude and location of errors.
Claims20
A real time apparatus for testing a DTV antenna transmitting system, wherein the antenna transmitting system transmits an original signal from a DTV transmitter to a DTV transmitting antenna, comprising:
- a probe, wherein the probe is connected in series with the DTV antenna transmitting system, and wherein the probe senses a signal traversing the DTV antenna transmitting system in real time and generates a received signal;
- an error detector which compares the received signal to the original signal to identify an error, and wherein the error detector identifies the magnitude and location of the error;
- and
- a processor, wherein the processor compares the magnitude of the error to a predetermined value.
A real time apparatus for testing a DTV antenna transmitting system, wherein the DTV antenna transmitting system transmits an original signal from a transmitter to a transmitting antenna, comprising:
- means for sensing in real time a signal traversing the DTV antenna transmitting system and generating a received signal;
- and
- means for comparing the received signal to the original signal to identify an error, and wherein the comparing means identifies the magnitude and location of the error.
