[. . . ] The Limit Test Application Software (Option LT) makes it easier to validate how your signals are performing compared to a known good condition. The Mask Test Application Software (Options MTH and MTM) enables testing against a well-defined telecommunication or computer standard providing automated statistical analysis of signal quality. Option LT ­ Limit Test Application Software A common method for understanding your signal quality is to compare against a known good or "golden" waveform. You can apply horizontal and vertical tolerances to the golden waveform to create a template that can be used for quick, accurate Pass/Fail testing. [. . . ] Clock recovery allows you to perform more reliable and accurate mask testing. The oscilloscope can reduce setup time for making a mask test measurement by performing an Autoset for vertical, horizontal, and trigger parameters on the source signal. Additionally, to reduce the chance of failures, the oscilloscope can Autofit the waveform to the mask to minimize hits within the mask. It can do this a single time following an Autoset or it can perform an Autofit after every triggered acquisition. The Mask Test Application Software provides flexible test definitions enabling you to tailor the test to your needs. You can run a test for a user-defined number of waveforms (up to 2. 14×109). The Repeat Test and Pretest Delay capability enables swapping of test locations before proceeding with a test over multiple cycles of the test. You can set the number of violations that can occur before a test status is considered failed. The oscilloscope can also perform a number of actions when a test fails or completes. Actions the oscilloscope can perform when a test fails include stopping the acquisition, e-mailing a message indicating the test has failed, Detailed mask test results show statistical information for the test. The results include information on test sample size, failures, total number of hits, and the number of hits in each mask segment. saving a waveform to file, logging the date and time of the failure, printing a waveform, sending a GPIB SRQ, and sending a trigger out pulse. Actions the oscilloscope can perform when a test completes include sending a GPIB SRQ and sending a trigger out pulse. The Mask Test Application Software provides statistical results from each test conducted. The results include Pass/Fail status of the test, number of waveforms/samples tested, number of violations found, and the total number of hits within the mask. A secondary display shows the total number of hits in each segment of the mask providing further insight into any mask violations. www. tektronix. com 3 Data Sheet Characteristics Option LT ­ Limit Test Characteristics Characteristic Description Option MTH, MTM ­ Mask Test Characteristics Characteristic Description Test Source Template Storage Template Creation Margins Lock Template to Waveform Highlight Hits Limit Test Status Limit Test Control Reset Actions on Limit Test Failure Any Ch1 ­ Ch4, Math1 ­ Math4, R1 ­ R4 Limit test template can be saved into any R1 ­ R4 location or to a file Vertical tolerance from 0 to 5 divisions in 0. 1m (1/10, 000th) division increments Horizontal tolerance from 0 to 5 divisions in 0. 1m (1/10, 000th) division increments Note: Use Average acquisition mode to help create a smoother limit test template Lock ON: Template automatically re-scales with source channel settings changes Lock OFF: Template does not re-scale with source channel settings changes Highlight Hits ON: Visually highlight any samples that fall outside of the limit test template Highlight Hits OFF: Samples that fall outside of the limit test template are not visually highlighted Passed: No samples from the test source have fallen outside of the limit test template Failed: At least one sample from the test source has fallen outside of the limit test template ON: Limit test is active and hits are being tracked OFF: Limit test is not active and hits are not being tracked Clears all violations in preparation for another test Stop Acq: When Stop Acq is ON, the instrument stops acquiring if a limit test fails Beep*1: When Beep is ON, the instrument beeps if a limit test fails E-mail: When E-mail is ON, the instrument sends an e-mail if the limit test fails Save Waveform: When Save Wfm is ON, failed waveform data is saved to a file Log Date: When Log Date is ON, the date and time for each failed limit test is recorded to a file Print: When Print is ON, the instrument sends the waveform to a printer if a limit test fails SRQ: When SRQ is ON, the instrument sends a GPIB SRQ command if a limit test fails Test Source Mask Creation *1 Not available on MSO/DPO5000 Series.
