The T344 is a compact 4-channel, 32 MHz arbitrary waveform generator. It incorporates four DDS waveform synthesizers that may be used independently or synchronously to produce polyphase signals. Waveforms include sine, triangle, sawtooth, noise, and precision square/PWM outputs. User-loaded arbitrary waveforms may be generated.
Test relays allow any output to be diverted to a test connector for in-system calibration verification. Built-In-Self-Test is provided.
