Introducing TestFlow Agentsdescribe the test in plain English,the agent drives your instruments

TestFlow Agents read the bench you actually have, write the automation and the test plan from your request, and run it on the real hardware. Editable test automation, not code snippets.

speaks to the instruments already on your bench

what shipped

Three things had to be true at once

An agent that writes test automation is only useful if it knows the bench it is writing for, and only trustworthy if you can read and run what it wrote. This release is all three.

the agent

Plain English in, real automation out

Ask for a VI sweep from 0 to 3.3 V in 100 mV steps and the agent writes the instrument automation and the structured test plan behind it. Both are editable before anything runs, and both are yours to keep.

the bench

Grounded in the instruments you own

The agent writes against the bench it can see: your models, your VISA addresses, your channels. Any vendor, over USB, LAN, GPIB, or serial. It is not generating a snippet for a datasheet it was trained on.

the run

It executes, then it reports

Values stream in against their limits step by step on real hardware, and the run ends in a report rather than a spreadsheet someone assembles on Friday. The next revision reruns the same workflow.

the loop

The request, the workflow it wrote, and the run

The chat, the workflow the agent generated, the ATOMS script behind it, and the executor stepping through it against the limits. Every panel here is the product’s own.

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.

PSU Load Transient.pdf · written by the run

how it works

From the request to the report, in four steps

Connect your instruments

Pick the manufacturer and model, paste the VISA address. Any vendor, no NI hardware required, no drivers to write.

Tell the agent what to test

In plain English. Or ask it what to test for a power-management device and pick from what it proposes.

Read what it wrote

The workflow and the executable automation arrive in seconds, side by side. Nothing is hidden between what you described and what will drive the bench.

Run it in the lab

Click Run. TestFlow drives the real instruments, checks every reading against its limit, and hands back the results.

available now

Put the agent on your bench this week

Connect one instrument, ask for one test, and see what it writes. That is the whole evaluation.
