Acute TravelData TD3116E/TD3216E — 16-Channel USB 3.0 Digital Pattern Generator - 1Mb/ch

Product Code: TD3116B

Acute TravelData TD3116E / TD3216E Pocket Data Generators 1) Product Introduction The Acute TravelData TD3116E and TD3216E are compact, PC-controlled digital pattern generators. In plain terms, they create clean, repeatable digital signals so you can stimulate, debug, and automate your boards without writing firmware first. They’re designed for electronic design engineers who need to bring up ICs, verify interfaces, and reproduce tricky timing issues. Plug into USB 3.0, select a protocol template like I²C, I3C, SPI or PMBus, and start driving pins with precise timing. The main problem they solve is time. Instead of building test firmware or wiring ad-hoc signal sources, you load or draw the patterns you need and run them at up to 200 MHz clock rates. That gets you to root cause faster and with fewer spins. 2) Key Benefits Cut bring-up time. Replace days of temporary firmware with minutes of pattern editing. Prebuilt protocol templates and vector import let you stimulate devices immediately and iterate quickly.

Make bugs repeatable. Capture a failing sequence on a logic analyzer, convert to vectors, and replay it exactly to confirm the fix. Repeatable stimuli mean confident, measurable progress. Improve test quality. Control edges, timing, and sequence logic (loop, wait-for-event, jump). You can explore corner cases—faster clocks, missing ACKs, odd chip-select timing—without rewriting code each time. Smaller, simpler alternative. Compared with bench-top AWGs or home-grown FPGA fixtures, TravelData is pocket-sized, USB-powered, and focused on digital patterns. Less overhead, more engineering. 3) Technical Specifications Headline specs for the 16-channel TravelData family (E-series models mirror the electrical performance of current B-series—see datasheet links below): Parameter TD3116E TD3216E Notes Data output channels 16 16 Plus 3 event inputs for sequencer control Max data rate (per channel) 200 Mb/s 200 Mb/s Internal clock 1 Hz to 200 MHz Pattern memory (per channel) ~1 Mb ~256 Mb Depth varies by model for long sequences Output levels 0.9–4.5 Vpp + Hi-Z 0.9–4.5 Vpp + Hi-Z Programmable; CMOS-style drive Protocols (built-in templates) I²C, MIPI I3C, MIPI RFFE, PMBus, PWM, SPI, sync/async counters Draw your own or import vectors (VCD/CSV/Acute-LA) PC interface USB 3.0 (bus-powered) Windows 7/8/10/11 software Size / weight ≈ 123 × 76 × 21 mm / ~680 g Pocket-friendly form factor Reference: Acute TravelData TD3000 series datasheet and product pages linked in “Getting Started”. 4) Real-World Problem Solving Problem A — “I can’t talk to the new power controller yet.” The challenge: You’ve placed a PMBus/I²C power manager on a new board. Firmware isn’t ready, but you need to bring rails up in a safe order and confirm margins. Waiting blocks layout fixes and reliability testing. Why it matters: Days slip while software catches up. Each delay risks missing a thermal or sequencing issue that will cost a respin. How TD3116E/TD3216E solves it: Connect the 16 outputs to SCL/SDA and enables. Load the PMBus template, type your writes/reads, and schedule timing with the internal 1 Hz–200 MHz clock. Add waits on “Power Good” using the event inputs. In an hour you’re toggling rails, sweeping voltages, and logging results—no MCU code required. Example: Program 0x21 output to 1.05 V, poll status, then assert EN2 after 10 ms. Loop the sequence while measuring ripple. If a rail misbehaves, you can slow the clock or insert deliberate NACKs to test fault handling. Problem B — “The SPI device fails once a day and we can’t reproduce it.” The challenge: A sensor on SPI drops a bit every few hours. You captured one failing trace on a logic analyzer, but the team can’t trigger it again to test the fix. Why it matters: Intermittent bugs kill schedules. Without reproduction, patches are guesswork. How TD3116E/TD3216E solves it: Convert the LA capture to VCD/CSV and import it. Map CS/SCLK/MOSI/MISO to output channels. Now you can replay the failing transaction with the same timing jitter, loop it, and sweep parameters (CS setup, clock polarity, added delay). When the fix sticks through 10,000 repeats, you know it’s real. Problem C — “We’re migrating from I²C to I3C and need confidence fast.” The challenge: New silicon supports MIPI I3C for higher speed and in-band interrupts. You must evaluate behavior across clock rates and oddball edge cases. Why it matters: Interface changes affect dozens of boards and suppliers. One wrong assumption can ripple through production. How TD3116E/TD3216E solves it: Start with the I3C template, then push clocks and bus conditions well beyond typical. Inject malformed sequences, simulate slow turn-arounds, or force extended timeouts. Measure the device response and document margins. Because TravelData is scriptable, you keep every test as a repeatable asset. Problem D — “Production needs a quick go/no-go without firmware.” The challenge: Manufacturing wants to verify GPIOs, reset timing,
