Abstract
Methods and apparatuses for displaying information for analyzing a signal transmitted in a communication system. The method can include displaying digital diagnostic data received from a monitoring interface of a transceiver. An eye-diagram for the signal is also displayed. The digital diagnostic data, network protocol analysis results, and/or the eye-diagram can be selectively displayed using a combined unit or stand alone units. Additionally, results of network protocol analysis can also be displayed with the digital diagnostic data and eye diagram.
Claims20
In a communications system, a method for displaying information describing a signal transmitted in the communication system, the method comprising the following:
- receiving the signals with a tapping device;
- transmitting the signal to a transceiver, the transceiver including a monitoring interface for performing digital diagnostic analysis of the signal, including real time access to access describing signal parameters;
- sampling the signal at a percentage of the harmonic frequency of the signal, the harmonic frequency of the signal being equal to the bit-rate divided by an integer;
- identifying a target as a midpoint between a maximum signal sample and the minimum signal sample;
- constructing an eye-diagram using the target as a reference point by identifying a point where multiple waveform crossings are displayed simultaneously in an overlaid time base;
- and
- displaying the digital diagnostic data received from the monitoring interface of the transceiver together with the eye-diagram for the signal.
An apparatus for displaying digital diagnostic data along with an eye-diagram, the apparatus comprising:
- a transceiver configured to receive the signal, the transceiver including a monitoring interface providing digital diagnostic data including real time access to information describing signal parameters;
- a processor including computer executable instructions that cause the processor to generate an eye-diagram when the computer executable instructions are executed;
- and
- a display configured to receive and display the digital diagnostic data along with the eye-diagram.
