摘要:
A method for testing a radio frequency (RF) receiver as a device under test (DUT) with one or more test instruments to provide a plurality of relative power correction factors, a plurality of received signal strength indication (RSSI) calibration factors, or both.
摘要:
A method and apparatus for testing a data signal amplifier having an output signal power dependent upon multiple signal power control parameters, e.g., signal gain control and amplifier bias current control.
摘要:
Methods for measuring the sensitivity of a data packet signal receiver are provided by varying the power level or modulation or both of a received data packet signal in a predetermined controlled sequence of data packet signals.
摘要:
An apparatus and method of operating automated test equipment (ATE) in a networked environment of multiple external test controllers. The system resources responsible for coordinating the shared uses of the ATE by the multiple external test controllers are centralized within the ATE. As a result, programming of the respective test controllers is simplified since the test controllers no longer need be responsible for communicating among themselves to coordinate or otherwise determine how and when access to the ATE is granted to any particular test controller.
摘要:
A method and apparatus for generating a reference transmission signal for use in testing a communications system. A data packet transmission signal containing a plurality of reference data is captured and digitized, following which reference data is retrieved. The retrieved data is used to modulate a carrier signal to produce a digital transmission signal, which is stored for later use, such that impairments in a signal from a traditional trusted unit are substantially removed, thereby minimizing uncertainty during later testing using such signal.
摘要:
A distributed test equipment system for testing analog communications systems. One or more analog signal receivers and one or more computers are connected via a packet-switched network such that each computer can remotely control and receive signal data from each receiver. Analog signal data measured by each receiver is available for relaying to each computer where it is processed for analysis in conformance with respective user commands.
摘要:
A radio frequency (RF) transceiver for providing substantially coincident communication of RF and related baseband control signals. Baseband circuitry within the transmitter and receiver sections provides for storage of related control data which can be used in real time to control processing of the transmitted or received data, respectively.
摘要:
The present invention relates to variants of a parent alpha-amylase. The present invention also relates to polynucleotides encoding the variants; nucleic acid constructs, vectors, and host cells comprising the polynucleotides; and methods of using the variants.
摘要:
A method of manufacturing a nicotine delivery product comprising nicotine and a cation exchange resin. More precisely, to a method for preparing a nicotine delivery product said method comprising (a) mixing nicotine, a cation exchange resin, an organic polyol and water to form a mixture wherein the total amount of water is from 26 to 45% by weight of the total mixture, and (b) removing water from the mixture to produce said nicotine delivery product.
摘要:
The invention relates to a method of relieving nicotine craving comprising the steps of providing at least one chewing gum comprising tobacco alkaloid to a user, providing relief of nicotine craving to said user by transferring of tobacco alkaloid from the chewing gum to the human body of said user by chewing of said chewing gum, said chewing of said chewing gum comprising a chewing process involving a transfer of tobacco alkaloid from said chewing gum above a threshold transfer rate in the period of about ½ minute to about 2½ minutes from initiation of said chewing process.
