Frequency Input Module for SCXI


8-Channel Frequency Input Module for SCXI—The SCXI‑1126 is an isolated frequency input module for SCXI. Each channel includes a frequency‑to‑voltage conversion circuit with programmable input range, threshold, hysteresis, and filtering. The output voltages of this module are multiplexed onto a single channel of a data acquisition device, so you can scan and acquire multiple frequency and analog input signals within a single high-speed scan operation.
