    Abstract: An integrated circuit is operable in two modes, including a test mode in which a pattern of variation is injected into a receiver's sampling clock and used to simulate jitter. Adding frequency offset, jitter or both, to this clock can be equivalent to adding jitter of an equal magnitude but opposite sign in a transmitted test signal. In this way, a clock can be produced that simulates timing variations that can be encountered during mission function operation of the device under test, while test input data is applied by local pattern generators or other data sources that, under test conditions, do not, or need not, exhibit such variations.

  • Patent number: 10263869
    Abstract: A network administrator utilizes a user client device to connect to a server within a network and provide a test plan comprises various tests to be performed on pairs of devices having physical connections within the network. The server selects, from the various pairs of devices, a pair of devices that are to be tested. Subsequently, the server transmits to each device of the selected pair of devices, instructions that may cause each device to perform the tests specified within the test plan. Once the tests have been completed, the server obtains the test results from the pair of devices and compiles these results.

  • Patent number: 10122442
    Abstract: A test and measurement system is disclosed. The system includes a data store with a data description of a received in-phase (I) quadrature (Q) symbol. The received IQ symbol is received from a transmitter associated with impairments, and the received IQ symbol is modified from a corresponding ideal IQ symbol by the impairments. A computer processor is coupled to the data store and generates an Error-Vector Magnitude (EVM) function that describes a difference between the received IQ symbol and the ideal IQ symbol in terms of a plurality of impairment parameters indicating the impairments. The processor then determines values for the impairment parameters that quantify the impairments. The values are determined by selection of values for the impairment parameters that minimize the EVM function.

  • Patent number: 10104582
    Abstract: In an example, a wireless communication system and apparatuses thereof are described. In an example long-term evolution (LTE) network, a first base station hands over a connection to a second base station. The first base station may be a (femto) home eNodeB (HeNB) or (macro) eNodeB. The second base station may also be a HeNB or eNodeB connected to a different gateway. The first base station may send “Handover Request” on an X2 connection, identifying the gateway that the second base station is connected to as the correct gateway. After sending a “Handover Request Acknowledgement,” the second base station correctly establishes a tunnel to a connected gateway device.

  • Patent number: 9918242
    Abstract: A dynamic channel selection approach for wireless communication networks is provided by measuring an ineffective communication metric on a currently-used channel. The network can switch channels if the ineffective communication metric from a device on the network satisfies a channel selection condition. To change the wireless communication network to the new channel, all network devices in the wireless communication network are instructed to switch to the new channel. As network communications start on the new channel, the ineffective communication metric measurements begin again on the new channel. Communications on the new channel continue until the channel selection condition is satisfied on the new channel, at which point another random selection of a channel is executed. The process continues in such iterations during the operation of the network and its network devices.
