AntennaVoltageTool is a app that helps you plan and check RF and optical setups fast. It estimates loop antenna voltage and turns field values into easy numbers you can use. You can find laser diode limits and slope, and plan cable current injection for lab tests.

Set up WDM channel spacing with guard bands, and pick the right fiber length to fix delay. Check photodiode gain and headroom so your output does not clip.

Measure coupler split and loss from input and two outputs in seconds. Verify VCSEL eye margins and keep links within spec. See your optical signal-to-noise clearly and build a safe OSNR budget.
