Preparing the Test Setup
Before performing a test, you have to specify the parameters to be used.
The application offers you two types of tests:
³
Generic: Useful to quickly test a DUT by using the default values
provided. Some analysis can be done with this option, but no Pass/Fail
status will be given.
³
Specified: Useful to perform a test using predefined parameters and
Pass/Fail limits. When selecting this test, the DUT Identification group
box is displayed (see Identifying the Current DUT on page 54).
You can specify the values for the scan parameters to be taken into
account during tests. These values include:
³
The number of channels to be tested: By default, the application
displays the total number of available power meter channels. However,
if you do not intend to work with all of the available channels, EXFO
recommends that you indicate the actual number of channels you are
using. This will save some testing time and a lot of disk storage space.
³
The tested wavelength range (in nm): By default, the application
displays the full range of the source in use. Changing this to a smaller
range will save disk storage space and may also reduce testing time.
