Load transient test: sweep 5-20 V, capture CH1

I’ll sweep the USB-PD levels inside a loop, step the dynamic load, and capture the scope response at each level.

one workflow that reruns

TestFlow Agent turns a plain-English request into automation that drives the instruments already on your bench

from plain English to a running bench, and back

Describe it, review what the agent wrote, run it on real hardware, and keep the workflow. The next revision reruns the same thing.

Download TestFlow

connect any instrument on your bench

TestFlow speaks to any instrument from any vendor, so the workflow you write today survives the hardware you buy next year

plain English and automation, one language

The agent writes the workflow it runs. Nothing is lost between what you described and what drives the bench

how it works

AI-native automation for electronics validation

Four steps, one workflow. TestFlow maps the bench, writes the test from a sentence, runs it on the real instruments, and keeps every result against the same workflow.

01.

Connect your instruments

TestFlow scans the bench, answers every VISA address it finds, and maps each instrument automatically. No drivers to write.

02.

AI generates your test workflows

Describe the test in plain English. TestFlow returns a structured workflow and the executable behind it, both editable before anything runs.

03.

Execute in the lab

Run it on the real instruments and watch the sweep, the log, and the limit checks resolve live.

04.

Review, analytics, and insights

Every run lands against the same workflow, so pass rates, drift, and out-of-spec parameters are history rather than a spreadsheet.

features

Everything your validation team needs to move faster

TestFlow gives your engineers a complete AI-native platform to plan, generate, execute, and report on chip validation, electronics testing, and systems testing. From first spec to final report.

Stop juggling tools. Start running reusable test flows.

Drop the tools you don't need anymore. TestFlow has instrument control, test sequences, data capture, and reporting built in.

Every tool speaks its own language. Nothing you set up in one carries into the next.

Validation work scattered across disconnected tools, spreadsheets, and hand-written scripts
