Exfo IQS-1600 SERIES

High-Speed Power Meter Module for use with IQS-500 Intelligent Test System

With the automatic gain range feature, 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 as1 ms), with sampling rates as high as 4096 samples per second.
The synchronization capability of the IQS-1600 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. For both, synchronization of all optical channels (2- and 4-channel models) is simultaneous.
