GL7-HSV   High-speed Voltage Module

Dynamic high speed recording module inputs voltage signal from displacement sensors to proximity sensors that fluctuates in high speed.  The signal recorded by a high resolution 16-bit Analog-to-Digital converter samples the measurement data at maximum 1MS/s (1µs) interval.
