2 Purpose
This test verifies that the Pulse Width Modulator (PWM) in the SRI is converting pulses to analog voltages correctly.
3 Components Tested
The PWM is part of the table motion control function.
4 Requirements
None

7 Expected Results
Output values are judged pass or fail. In the event of failure, the details of the failure can be found in the GE System Log.
In the case of errors click the 1st Error number to see the nature of the error.
If this test fails with a NO-RESPONSE type error, use the SRI STIF LoopBack test to determine if the problem is in the SRI module or the fiber optic connections.
8 Etcetera
Click Calculate Time to get an estimate of the time it will take to run the selected diagnostics.
Other than Test Iterations, the Test Options settings should not be changed from their default settings unless instructed to do so by a GE Healthcare engineer. There are very few circumstances when these settings ever need to be changed.
