The results of the test will also be storedin an Excel .XLS file that can be used for further data analysis. Included inthe test report are the configuration settings for the test equipment, testexecution times, and comments for each test.Counting Bit Errors using Oscilloscope Error Detector, in DUT Receiver Loopback.Loopback Initiation and RetentionBefore the Receiver test can start, the device under test must be put in theproper test mode, called Loopback, where the DUT loops the incomingsignal at Rx directly to the Tx port. Once the Loopback is set on the DUT,then the Arbitrary Waveform Generator sends a Burst mode signal withrecommended patterns for all measurements. The M-PHYRX Automationsoftware will allow the user to configure the Loopback settings initially,and retain them for subsequent test executions by sending the signalcontinuously during the transition from one test to another.Ease of Testing with Pre-calibrated PatternsThe AWG (Arbitrary Waveform Generator) patterns are generated andfactory calibrated to ensure the impairments are within the specificationwith given golden accessories. This simplifies the number of patterns aswell as limits the time-consuming calibration routines. Both the AWG andOscilloscope Error Detector work together concurrently in Loopback mode,and pre-calibrated signals enable you to perform each measurement withinthree minutes of time.Pass/Fail ReportThe Report tab provides a view of test results along with Pass/Fail statusand bit error counts. Upon completion of the test, a comprehensive reportPowered by NI TestStandThe TekExpress automated compliance software uses NI (NationalInstruments) TestStand to manage and execute its test sequences. AWindows user interface is provided in the TekExpress software for simpleand complete operation of compliance measurements. However, ifyour validation and debug needs go beyond the features offered by theTekExpress software, a full version of NI TestStand can be used to develophigher-level automation sequences to control the TekExpress software.NI TestStand is the de facto industry-standard test managementenvironment for automating test and validation systems. NI TestStand isused to develop, manage, and execute test sequences, and to integrate testmodules written in any test programming language through an open andflexible architecture. Customers who own NI TestStand and purchase theTekExpress software will be able to write scripts using NI TestStand that callthe TekExpress software with a detailed list of commands. This commandset allows the NI TestStand user to recall and save TekExpress softwaresetups, control individual test parameters, control test selections, changeUI selections, change global parameters, start execution, query currentexecution status, and receive measurement results.For device validation, it’s often desirable to make multiple runs of a singledevice using different operating conditions such as temperature andpower supply voltages. This is sometimes referred to as ‘four-cornerstesting’, (testing to low-high temperature and low-high supply voltages).For four-corners testing, NI TestStand supports drivers for a wide rangeof temperature chambers and power supplies. NI TestStand can beused to control the temperature chamber and then call the TekExpresssoftware for a compliance test using the limited command set. Foradjusting power supply voltages, the power supply control sequencefile within the TekExpress software can be modified using a standardNI TestStand sequence file. So if your company already uses NI TestStandfor automation, your test engineers can incorporate commands to run theTekExpress compliance software directly into their test sequences.www.tektronix.com 3
