Lesson 3 – TIA Test Method Programming and Test Execution
3-3
TIA Example Test Method
You will now see an example of a test method for a TIA test. The
test method contains all the basic elements and uses the API
function that have been discussed in the previous sections.
The test method performs a frequency test at input channel 1 (pin
tia_in4) of the TIA. The external trigger signal is used to arm the
TIA.
The following figure shows the front-end and TIA setup for the
test.
Front-End and TIA Setup for Example Test Method
The frequency measurement will be performed once (Sample Size
=1) after the external trigger signal has been received (Source =
EXTERNAL).
The frequency result is determined by measuring the time of 120
periods (Stop Count - Start Count = 120) and then calculating the
frequency from it.
