DWDM Passive Component Test System 117
10 Testing Multiple DUTs with the
LabVIEW Application
The MultiPath Testing Option comes with a “prebuilt” application and with
a series of VIs and COM functions you can use to develop your own MPT
application.
If you choose to build your own application and you need information on
referencing the system, see Referencing the System with MultiPath Testing
Option on page 113.
The LabVIEW application provided with the MultiPath Testing Option
allows you to:
³
Reference and calibrate the system
Referencing and calibrating the system are necessary in order to
ensure optimum accuracy. References are saved to a file for future
tests. References are valid as long as rigid and semi-rigid patchcords
do not move, and no new power optimization is performed. Power
optimization deletes all the previous references, so they will have to be
taken again. Referencing and calibrating include:
³
performing a null measurement
³
optimizing power
³
calibrating the wavelength response of the system
³
calibrating the system for return loss (ORL) testing
³
performing reference measurements for IL, PDL and ORL.
³
Define the connectivity of the devices to be tested (DUT), save
connectivities and reload them.
³
Configure tests.
³
Perform tests on the defined DUTs sequentially.
³
View test results, export them and print them.
