2 Getting Started and Using Masks
Getting Started and Using Masks Telecommunications (telecom) and data communications (datacom) industries have established standards for equipment manufacturers. One of these standards defines the electrical parameters for waveforms. By applying these standards, both telecom and datacom equipment manufacturers can ensure that their equipment will operate properly together by first certifying waveform integrity.
Getting Started and Using Masks Make a copy of the Mask Test disk How Infiniium does Mask Testing When you start the mask test, Infiniium creates a database that has unique locations for every pixel in the waveform viewing area. Each location in the database has a 21-bit counter for a maximum count of 2,097,151. Each time a data point from a channel memory illuminates a pixel in the waveform viewing area, the counter for that pixel is incremented.
Getting Started and Using Masks To install the Standard Masks To install the Standard Masks Use the copy of the Mask Test disk to install standard masks onto the Infiniium hard drive. The Mask Test disk contains many of the available standard masks that you may need to use during mask testing. 1 2 3 4 Insert the copy of the Mask Test disk in the floppy drive. From the oscilloscope main menu, select Analyze, then Mask Test. In the Mask Test Setup dialog box, select the Enable Mask Test control.
Getting Started and Using Masks To calibrate the oscilloscope To calibrate the oscilloscope Your Infiniium should be at optimum performance when performing mask testing. If your Infiniium has not been calibrated in the last year or if the Calibration ∆Temp is greater than ±5 °C, you should recalibrate the oscilloscope before performing a mask test. You can find the Calibration ∆Temp in the Calibration dialog box by clicking on the Utilities menu and selecting Calibration.
Getting Started and Using Masks To choose a proper probe for Mask Testing To choose a proper probe for Mask Testing You can use any oscilloscope probe that fits your application. Depending on the type of waveform you are testing, you may need to use one of the probe adapters. Calibrating the probe adapter Depending on the requirements of your Telecom or Datacom industrial standard, you may need to use the E2622A 75 Ω probe adapter or the E2621A differential probe adaptor.
Getting Started and Using Masks To get your waveform on the oscilloscope display To get your waveform on the oscilloscope display When doing mask testing, you will try to fit the mask to your waveform. This is how you will verify whether your waveform meets the acceptable electrical parameters defined by the standard mask. By having your waveform displayed on the oscilloscope screen before doing mask testing, when you load and use the mask, you will know immediately if the waveform passes the mask test.
Getting Started and Using Masks To enable the Mask Test To enable the Mask Test 1 Click Analyze, then Mask Test to access the Mask Test Setup dialog box. 2 In the Mask Test Setup dialog box, click Enable Mask Test to checkmark the box. When enabled, a Mask Test tab appears beneath the waveform viewing area. Checkmark to enable the Mask Test.
Getting Started and Using Masks To load a Mask To load a Mask 1 Click Analyze, then Mask Test to access the Mask Test Setup dialog box. 2 Make sure the mask test is enabled. 3 Click the Load Mask... button. 4 In the Load Mask dialog box, click the Mask Test Source field to select an oscilloscope channel for the mask test. The active channel is the default. 5 Click the Drive: field and select the drive where the mask you want to load is located.
Getting Started and Using Masks To align a Mask to the waveform To align a Mask to the waveform 1 Access the Mask Test Setup dialog box and make sure the mask test is enabled. 2 Locate the Use File Setup When Aligning option.
Getting Started and Using Masks To start and stop the Mask Test To start and stop the Mask Test 1 Access the Mask Test Setup dialog box and make sure the mask test is enabled. 2 At the bottom of the Mask Test Setup dialog box, locate the start and stop mask test buttons. • The green triangle starts the mask test. • The red square stops the mask test. Starts mask test in the Mask Test Setup dialog box. Stops mask test in the Mask Test Setup dialog box. Starts/stops mask test from the Mask Test tab.
Getting Started and Using Masks To understand the Mask Test tab description area To understand the Mask Test tab description area After you have enabled the mask test in the Mask Test Setup dialog box, you will see a Mask Test tab on the lower left of the oscilloscope screen, beneath the waveform viewing area. The description area below the Mask Test tab shows: • Mask title • Amplitude specifics (for ANSI T1.
Getting Started and Using Masks To run the Mask Test conditionally To run the Mask Test conditionally 1 Access the Mask Test Setup dialog box and make sure the mask test is enabled. 2 Click the Run Until selection arrow to view the options. a If Stop on Failure is disabled, you can stop the mask test based on the following conditions: • Forever The mask test will run continuously. This is the default selection.
Getting Started and Using Masks To stop the Mask Test on the first failure To stop the Mask Test on the first failure 1 Access the Mask Test Setup dialog box and make sure the mask test is enabled. 2 Click Stop On Failure to checkmark the box. 3 Run the mask test. When the mask test encounters the first failure, the test will stop and the failure result will be displayed in the Mask Test tab description area.
