TGF4000 Series Arbitrary Function Generators

The TGF4242 is a high-performance dual-channel arbitrary function generator, delivering advanced signal generation capabilities from 0.001 mHz to 240 MHz. Featuring two identical, full-performance output channels, the instrument supports independent, coupled, or tracking operation, ideal for complex multi-channel applications.

For engineers demanding accurate signal synchronization, the TGF4242 offers ultra-precise channel-to-channel phase control with 0.001° resolution, ensuring reliable phase alignment. A vibrant 4.3-inch high-resolution color display enhances usability, with each channel clearly differentiated by distinct colors for easy visual recognition during configuration and operation.
