The PTU-3 mod. 2 is a versatile trigger control unit designed for precise timing and synchronization in measurement, recording, and testing systems. It supports multiple trigger sources – optical, acoustic, voltage, and logical – and provides three independent output channels with two configurable input channels. Each output can be individually adjusted for delay, polarity, and pulse duration. The integrated graphical display ensures clear control and feedback during operation.
The device features Bluetooth / Wi-Fi connectivity for mirroring and remote control, a built-in QuickCharge 2.0 charger, and IPx4 protection. Powered by Li-Ion batteries, it combines high flexibility with portability, making it ideal for both laboratory and field applications.
