Abstract

The present invention discloses a system and method for testing a plurality of data packet signal transmitters with a wider data packet signal bandwidth using a plurality of data packet signal testers with a narrower data packet signal bandwidth. Using multiple packet signal testers with narrower receiver bandwidths to process the respective portions of the wider bandwidth of the packet signal generated by the device under test (DUT) enables the use of lower cost, narrower bandwidth test equipment to Test wide bandwidth signals.

Description

Background technique [0001] The invention relates to testing a data packet transceiver, in particular to testing a broadband data packet signal transceiver using a narrowband testing instrument. [0002] Many of today's electronic devices use wireless technology for both connection and communication purposes. Because wireless devices transmit and receive electromagnetic energy, and because two or more wireless devices may interfere with each other's operation due to their signal frequencies and power spectral densities, these devices and their wireless technology must comply with various wireless technology standard specifications. [0003] When deciding on these wireless devices, engineers take extra care to ensure that the devices meet or exceed the specifications set by the standards for each of the wireless technologies they include. In addition, when these devices then enter mass production, they are tested to ensure that manufacturing defects will not cause improper ope...
