The EXFO IQS-1643 Power meter module features automatic gain range, power fluctuations of up to 95 dB stabilize within 15 ms, and a continuous sampling rate of up to 256 samples per second can be achieved. You can also manually select the gain range for individual channels. In this case, dynamic range is limited to the selection; but in return, stabilization times are shorter (as little as 1 ms), with sampling rates as high as 4096 samples per second. The synchronization capability of the IQS-1643 High-Speed Power Meter complements the high sampling rates. This high-speed power meter provides two types of synchronization triggers, a power level trigger and a TTL voltage (electrical) trigger. The IQS-1643 comes with front panel InGaAs detectors, with an impressive -85 dBm sensitivity. Specifications. Number of detectors: 4. Detector type: InGaAs. Detector size: 1 mm. Wavelength range: 800 to 1700 nm. Power range: 9 to -85 dBm. Uncertainty: ±5% (0 dBm to -55 dBm). Linearity: ±0.015 (0 dBm to -55 dBm). Power resolution: 0.001 dB (9 dBm to -40 dBm). Wavelength resolution: 0.01 nm. Stabilization time automatic range: < 12 ms (9 dBm to -85 dBm). Sampling rate (sample/s/channel) fast acquisition mode: up to 4096. Fiber type: 5/125 to 62.5/125 µm. External trigger input voltage: 0 to 5 V (TTL).
