Laser RIN measurement with Atelase RT40
RT40 adds colors to "RIN: <155 dB/Hz" spec sheets.
The RT40 Difference: Built-in Calibration Source. High accuracy enables measuring RIN that is a fraction of a dB above the fundamental shot noise RIN limit.

How It Works
We provide an optional laptop that controls both RT40 and your ESA to quickly start measuring RIN. The RT40 can also be part of your test rack, remotely controlled with VISA-type commands. The video below shows how a $260 TinySA ESA can be used to measure RIN with shot-noise-limited sensitivity.
