The device EL_BULT14 is able to produce TTL trigger pulses out of analog signals from optival (Laser), reluctance or capacitive and eddy-current sensors.
Each of the 14 channels has a corresponding input (Probe In) and trigger pulse out (Pulse Out) BNC connector on the rear side of the device.
The channel selectors can be used to route the amplified as well as the trigger pulse signal from one of the 14 channels to the front BNC connectors for monitoring purposes.

The amplifier EL-LNA-2 is designed as a differential low noise amplifier with two gain stages of x10 and x100 with a full bandwidth of 20 MHz (at G=10)

While the EL-LNA-2 is matched to connect to an Elsys highprecision Transient Recorder it is also suitable for any 3rd party data acquisition system.
