Optical power meter
The Model FM8515B Issue 2 optical power meter has a low-end dynamic range that has been extended to 70 dBm, and an upper end at +5 dBm. The original units were calibrated down to -60 dBm. The modification has been made possible by a microcontroller-based measuring circuit that assures linearity over eight logarithmic decades. Battery life has been extended to approximately 100 hours. The meter can be calibrated in less than 30 min. The model includes a reference-storage feature, as well as low battery indication, auto power off, and readings in dBm, dBr, and microwatts.
