Legendary source stability
What it does:
High quality fiber pigtailed sources with low loss interchangeable connectors improve test source stability. For example, we specify the source re-connection repeatability as 0.1 dB.
We accurately set the laser power, so power meter referencing is a more reliable process. The actual power will be very close to the nominal power.
SM lasers have a tight 20 nm wavelength tolerance, for improved long distance test repeatability.
MM LEDs are mode controlled to meet Encircled Flux requirements with no additional conditioning patch leads.
The Autotest feature has high functionality with data transfer, This reduces laser warm up, so also makes measurements more stable.
User benefits
More accurate and repeatable loss test results under all conditions.
Save time with less referencing
For truly state-of-the art source stability, please see our Zero warm-up sources & loss testers, which take source stability to a whole new level for a modest extra cost.
