The Acute Technology TravelData TD3116E/TD3216E is a compact, PC-based digital pattern generator for exercising and validating digital interfaces. Via USB 3.0, it provides up to 16 data output channels plus dedicated event inputs for flexible triggering and synchronisation. A programmable clock supports very low rates for bring-up through to high-speed operation, while deep per-channel memory allows long, repeatable stimulus sequences.
The TravelData family includes multiple variants. If you need a smaller channel count, see the related TD3008E 8-channel model. All models use the same Windows application for editing vectors, importing user patterns (e.g., VCD/CSV) and generating common bus protocols such as I²C, SPI, PWM and others. Typical use cases include protocol emulation, state machine testing, power-up sequencing, and regression stimulus during firmware iteration.
Why consider TravelData?
Engineers choose TravelData when they need a portable digital stimulus tool that exceeds the capabilities of simple GPIO toggling or microcontroller test code. Compared with bench instruments, it offers a small footprint, deep vector memory, multi-channel correlation and an affordable route to complex, protocol-aware testing—ideal for lab or field use with a laptop.
