Setting Up Your Multifunction Loss Tester

16 FTB-3930

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).
