[TSM] Index Time Display on OI

[vincent.lai@tctechinc.com]

Hi All

I am customizing TestStand semiconductor module OI and would like to show indext time on it.

During my development, I have two questions:

1. How do I get the index time?

    I searched TestStand and TSM help.  It seems TSM API doesn't offer get index time method.

    TSM APIs provide "GetAverageSockerTime()", "GetAverageCycleTIme()", "GetWindowAverageCycleTime()", and "GetWindowAverageSocketTime()" methods but not "GetAverageIndexTime()". 

    Shall I subtract GetWindowAverageSocketTime() from GetWindowAverageCycleTime?

2. What is the index time I get from 1?

    Based on the help page http://zone.ni.com/reference/en-XX/help/373892H-01/tssemiconductor/execution/

    I assume the GetWindowAverageCycleTime() - GetWindowAverageSocketTime() returns me "handler index time".  In some situation, let me assume I have a very fast handler with a very short index time, while my test plan is long and it takes TestStand long time to generate test reports for each Batch , i.e handler index time > tester index time; in this case, what do I get from "GetWindowAverageCycleTime() - GetWindowAverageSocketTime()".

Thank you

Vincent

You are correct that subtracting the Cycle Time from the Socket Time will give you the Handler Index Time, and I think that is probably the best way to do it with the current API.

As for your second question, I believe that since the handler/prober driver is waiting for the Controller Execution to call StartOfTest, it will not be able to notify a start of test until the full Tester Index Time has completed. Because of that, you'll still end up with the Handler Index Time.
