Case study / Power Test & ATE · US + UK Twin Sites
Intepro Systems.
Two sites, two rulebooks: a US test-equipment catalogue where every spec cites its clause, and a British twin engineered never to copy it.

What the project
needed to do.
Intepro Systems has built programmable power and automated test equipment since 1981, from Tustin, California and Sandhurst, England. Campbell Digital Studio rebuilt its American site as a 128-URL, standards-first catalogue at inteprosystems.com — a parametric equipment finder, ten standards pages where every limit cites its clause, and application × standard pages for aerospace, defence, EV, grid and semiconductor test — and built inteprosystems.uk as a separate 77-URL site for British programmes: G98/G99, UKCA, Def Stan and DEFCON, written in British English and gated at build time against becoming a copy of the .com.
Intepro sells to engineers who have to prove equipment against a named standard — and its old site made them do the proving. Specifications sat in PDFs, the standards the hardware exists to satisfy were barely named, and the company's own engineering was hard to tell apart from the partner hardware it integrates. The UK side of the business had been served by a near-identical mirror of the American pages: no Def Stan, no G99, no UKCA, not a pound sign. Two countries, two regulatory regimes, and one site pretending they were the same market.
Engineers can verify every limit against the standard itself — the site earns trust the way a datasheet does, not the way a brochure tries toWhat moved the needle
What it looks like,
on screen.
The deliverables,
line by line.
Two sites that share a family resemblance and nothing else. inteprosystems.com is a standards-first catalogue: a parametric finder across 25 systems, ten standards pages whose every limit cites its clause, application × standard pages for the sectors Intepro actually serves, product pages that attribute partner hardware to its manufacturer, a support library of 34 documents and a 145-term glossary, and a legacy redirect map so none of the old site's search equity is thrown away. inteprosystems.uk is a separate build for Intepro UK Limited in Sandhurst — compliance briefs on G98, G99 Issue 2, UKCA, Def Stan, DEFCON 658 and JOSCAR, a calendar of the dates the market misquotes, and systems pages that lead with Intepro's own IP. Both run on Next.js with no CMS, and both refuse to deploy if a figure loses its source.
- Two live sites on two domains — inteprosystems.com (128 URLs) and inteprosystems.uk (77 URLs), verified on both sitemaps 2026-09-22
- Parametric equipment finder — filter every system by power, application, test standard or part number
- Ten standards pages with cited limits — MIL-STD-704F, DO-160G §16 and §17, MIL-STD-461G CS101, IEEE 1547.1, LV 123/148, ISO 16750-2, JEDEC, IEC 61000 — each value tied to the clause, table or figure it comes from
- Application × standard pages — avionics, military ground and shipboard, EV batteries, traction drives, power semiconductors, grid-tied inverters, PSU manufacturing, medical
- Product pages across ATE systems, AC sources, DC supplies and electronic loads, with own-IP and partner hardware attributed to the company that actually makes it
- Competitor-replacement pages for six legacy instruments engineers are looking to replace
- Support library — 34 downloadable documents and a 145-term glossary
- Legacy URL map — the old site's indexed URLs redirected to their new homes, checked against the built output before every deploy
- inteprosystems.uk — Intepro UK Limited, Sandhurst: eleven compliance briefs covering G98, G99 Issue 2, UKCA, GB/EU/Northern Ireland market access, Def Stan 61-005, 59-411 and 05-138, DEFCON 658 and JOSCAR
- A UK compliance calendar — thirteen dates the British market commonly gets wrong, each with the correction and its source
- Build-time divergence gate — every UK page is fingerprinted against the .com and fails the build above 40% five-word overlap
- British-English gate that catches Americanisms and the over-corrections a careless pass introduces
- Statutory-disclosure gate — the UK company's registered details must render, or the build stops
How the build
earns the call.
The search surface is the one competitors can't copy: the standards themselves. Part numbers are contested by every reseller; 'MIL-STD-704F power testing' and 'G99 type-test bench' are not. Each application × standard page exists only where the pairing is real — invalid intersections were pruned rather than published. On the UK side, the divergence gate is the SEO strategy: two domains saying the same thing collapse into one in Google's index, so the build measures the overlap on every deploy. Conversion is engineer-to-engineer — request a quote on the .com, talk to an engineer on the .uk — with the requirement pre-filled from the page the buyer is standing on.
A defence-adjacent engineering company now presents itself the way its customers evaluate suppliers: by evidence. The American site gives buyers a specification path from the clause they must satisfy to the system that satisfies it, and the British site gives Intepro UK a credible, independently indexable presence in its own regulatory language. Both sites are newly live, so this is the foundation rather than a results report — built so that every claim on it survives an engineer checking.
The engineer who specifies a 400 Hz aircraft power source doesn't read adjectives — they read the clause. So this build treats every number like evidence: each limit on a standards page carries the table, figure or paragraph it came from, and the build refuses to ship a figure that can't prove its source. Then it does the harder thing twice. America and Britain test the same physics against different documents — MIL-STD-704 and IEEE 1547 on one side, Def Stan 61-005 and G99 on the other — so Intepro got two sites, not one site with a flag switcher. The British site is measured against the American one at build time and fails if it starts to sound like a copy.Studio rationale
