Patent ID: 8112669

Claim:
A test system for measuring operating parameters of a distributed system, said test system comprising: a testing device including a connector for connection to a test point, a memory for storing instructions for a plurality of test sequences, a short range communication structure capable of transmitting said results of said collecting and analyzing data, and a processor responsive to commands for executing said instructions to perform said test sequences, collecting and analyzing data responsive to said test sequences and storing results of said collecting and analyzing data; and a controller physically separate from said testing device including a manual input arrangement, a display, a processor responsive to said manual input arrangement for controlling storage and execution of said instructions for a plurality of said test sequences in said testing device and receiving, storing and further analyzing results of said collecting and analyzing by said testing device, a communication link complementary to said short range communication structure between said testing device and said controller for communicating control signals and said instructions for a plurality of said test sequences from said controller to said testing device and communicating said data collected and analyzed by said testing device to said controller when said testing device is within communication range of said controller over said communication link including said short range communication structure and communicating said data collected, analyzed and stored by said processor of said testing device during at least periods when said testing device is not within communication range of said controller over said communication link including said short range communication structure when said testing device is brought within said communication range, and a display for displaying said results of said collecting and analyzing, when received from said testing device, and results of said further analyzing of said results.
