Measurement & Test Services

Measure what is otherwise only assumed: radio and RF, thermography, measurement data transmission. We measure on site or in the lab – with our own spectrum analyser, thermal imaging camera and field-strength equipment –, set up and automate measuring stations. You get figures you can decide on. No accredited test reports, but reliable engineering measurements with a documented set-up.

Services

Two sides of one thing: we measure for you – and we get your measurement equipment running.

  • 01

    RF measurements

    Spectrum, levels, occupancy and interferers in the frequency domain: pre-measurements before the EMC test, analysis of interference in operation, assessment of antennas and cable routes. With our own spectrum analyser, on site or in the lab. Indicative measurements with a documented set-up – so you know where you stand before the accredited lab measures.

    Digital and analogue radio

    Measure and assess radio links: range, field strength, link quality, interference – for analogue and digital radio systems in workshops, along lines and on sites. Field-strength measurement with our own equipment, protocol analysis where digital schemes are involved.

    LoRa and mesh networks

    Plan, build and survey sensor networks: LoRa and mesh topologies for sites, plants and vehicles where Wi-Fi and cellular do not reach or are too expensive. Measure coverage, place gateways, carry the data path through to the dashboard.

    Measurement data transmission and telemetry

    Get readings to where they are needed: connect sensors, buffer and transmit data – wired, by radio or cellular –, acquire time-synchronously, store and visualise. From a single measurement set-up to distributed monitoring.

    Thermography

    Thermal images of control cabinets, assemblies, drives and plants under load: loose terminals, overloaded components, unbalanced phases and hotspots on circuit boards become visible before they fail. With our own thermal imaging camera, comparative measurement and documentation.

    Measuring stations and instrument service

    Instruments are only as good as their set-up: we set up measuring stations, remote-control oscilloscopes, generators, power supplies and data loggers (SCPI, Python), automate recurring measurements and document measurement uncertainty and set-up. Existing instruments are checked, configured and integrated into test procedures.

Typical assignments

This is what the requests look like that customers bring to us.

  • 01

    "The radio always drops out at the same spot."

    Measure coverage and interferers, show the cause, adjust antenna or location – with before-and-after measurement.

  • 02

    "We want sensors on the site, but without cables."

    LoRa or mesh pilot: measure range, place gateways, data into the dashboard – in weeks, not quarters.

  • 03

    "The device fails after two hours."

    Thermography under load shows the hotspot; an RF measurement shows whether an interferer is behind it.

  • 04

    "Before the EMC test we want to know whether we pass."

    Pre-compliance measurement in our own set-up, fix weak points, then into the accredited lab.

  • 05

    "An employee does the measurement by hand – every day."

    Automate the station: remote-control instruments, capture values, generate the report – reproducible instead of dependent on one person.

  • 06

    "The measurement data sits on the device and never leaves."

    Build the transmission chain: buffer, radio or cellular, timestamps, database, dashboard.
