The Exfo IQ-3200B Return Loss Meter uses a low-drift InGaAs photodetector coupled to a source port and a measurement port. When connected to any stable source (0 dBm output power), it enables measurements down to an impressive -80 dB. Based on state-of-the-art optical components, sophisticated signal processing, a dark current nulling function and a detailed calibration procedure, the IQ-3200 provides accurate (± 0.35 dB), linear (± 0.015 dB), high-resolution (0.001 dB) measurements, ideal for demanding lab and production-floor applications.
