Abstract
A margin testing device includes at least one interface structured to connect to a device under test (DUT) one or more controllers structured to create a set of test signals based on a sequence of pseudo random data and one or more pre-defined parameters, and an output structured to send the set of test signals to the DUT. Methods and a system for testing a DUT with the disclosed margin tester and other testing device are also described.
Claims20
A margin testing device, comprising:
- at least one interface structured to connect to a device under test (DUT);
- one or more controllers structured to create a set of test signals based on a sequence of pseudo random data and one or more pre-defined parameters;
- and
- an output structured to send the set of test signals to the DUT.
1 more element
A method of operating a margin tester, comprising:
- generating a pseudo random binary data sequence;
- creating a set of test signals based on the generated sequence of data and one or more pre-defined parameters;
- and
- sending the set of test signals to the DUT.
1 more element
A testing system, comprising:
- a device under test;
- an oscilloscope coupled to the device under test through one or more data probe through which the oscilloscope may capture signals on the device under test;
- and
- a margin testing device, including:
- at least one interface structured to connect to the device under test,
- a pseudo random binary sequence generator configured to generate a sequence of data,
- a controller to generate test signals that represent the generated sequence of data,
- an operating envelope definer to limit the test signals to one or more pre-defined signal parameters, and
- an output structured to send the limited test signals to the device under test.
