a. Center Wavelength (λc)

For JS-VISG-M-S, λc is typically 1310 nm or 1550 nm (telecom O- or C-band) or 1064 nm (fiber laser version). The manual warns that operation even ±20 nm outside the specified band will cause isolation to drop from >30 dB to <5 dB. js-visg-m-s manual

11. Troubleshooting

• No signal: verify Source.type and data shape; check sampleRate mismatch.
• Slow rendering: switch to 'event' framePolicy, lower FFT size, enable webgl.
• Blurry canvas: set devicePixelRatio in createComponent to window.devicePixelRatio.
• Colors not matching: supply a custom colormap array of 256 RGB triplets.
