Setting Up Your Multifunction Loss Tester
16 FTB-3930
Setting Pass/Fail Thresholds
Setting Pass/Fail Thresholds
You can define groups of thresholds to specify acceptable power (in W or
dBm), power reference (in dB), F
ASTEST loss (in dB and dB per distance
unit) and ORL values (in dB) for each wavelength.
Thresholds are supplied by system manufacturers and depend on the
system deployed.
Measurements exceeding a threshold are shown with an exclamation
mark. In the test tabs, these measurements also have a red background.
Note: When transferring results from handheld unit to computer, thresholds are
not transferred along with results.
IMPORTANT
Thresholds are not saved with measurements. Results are compared
to the threshold group currently associated to the file (for F
ASTEST
results, not necessarily the master unit).
