1.3.3.4 Pulse Width Test

To perform the pulse width test, follow these steps:

  1. To capture the signal on the rising edge of the signal, set the trigger of the oscilloscope.
  2. Measure the pulse width. Measured pulse width must be within the specified range. Otherwise, the programmer is out of calibration and needs servicing.

    The following figure shows the allowable range of the pulse width test.

  3. To terminate the test, on the SS4 programmer, press the START push button.
  4. Remove the test probes from the SM48D adapter module.
  5. To ensure that there was no programmer damage during the verification of calibration test, perform programmer diagnostics test with the SM48D.

  6. To exit the Sculptor Software, close its window or go to File and click Exit. At this point, the programmer turns-off.
