High frequency<\/h2>\n

The high-frequency department is all about the science of measuring electrical voltages, currents, and powers that change rapidly, such as with radio frequencies (RF), microwaves, and electromagnetic fields.<\/p>\n

 <\/p>\n

High-frequency signals find their use in communication technologies such as mobile phones, radars, and satellites, but there are also many applications in the automobile industry, healthcare, and semiconductor industry, like the production of chips. It is crucial for these technologies and advancements to be able to measure high-frequency signals reliably and accurately. <\/p>\n

 <\/p>\n

VSL offers, among other things, unique facilities aimed at the growing need for accuracy and traceability for on-wafer, high-frequency systems and quantum systems, but also the more classic Vector Network Analyzer (VNA) systems and RF power measurements.[\/vc_column_text][\/vc_column][vc_column width=”1\/3″ css=”.vc_custom_1757064515093{margin-top: 0px !important;margin-right: 0px !important;margin-bottom: 0px !important;margin-left: 0px !important;padding-top: 0px !important;padding-right: 0px !important;padding-left: 0px !important;}” el_class=”full_width_responsive tablet_expert”]

VNA calibration services<\/h2>\n

VSL provides the most accurate RF measurements in the Netherlands. To guarantee this, the high-frequency department is split up into several facilities: <\/p>\n

<\/h4>\n

RF Power<\/h4>\n

The RF Power facility at VSL has the capability to make precision measurements for power sensors in a frequency range from DC to 50 GHz. Here, powers from 1 \u03bcW to 10 mW can be measured where absolute uncertainties of 5.0E-3<\/sup> to 1.5E-2<\/sup> can be achieved. The facility is designed to measure various connector types (2.4 mm, 3.5 mm, 2.92 mm, APC, and N-type connectors). Typical measurements made in this state-of-the-art laboratory include determining the calibration factor and absolute power of power sensors and signal generators. <\/p>\n

 <\/p>\n

S-parameter measurements of coaxial components<\/h4>\n

VSL operates high-quality VNA measurement setups, capable of covering a frequency range from 10 Hz to 50 GHz. These setups allow for the calibration of items such as calibration kits, attenuators, and other VNAs by measuring reflection and transmission parameters (S-parameters). Calibrations of multiport devices are also possible. S-parameter measurements are offered for various connector types, including 2.4 mm, 3.5 mm, 2.92 mm, APC, and N-type connectors. For more information about the uncertainties we can achieve at VSL, please refer to our . ISO\/IEC 17025:2017 accreditation.<\/span><\/p>\n

 <\/p>\n

S-parameter measurements of on-wafer components<\/h4>\n

VSL houses state-of-the-art measurement facilities for characterizing the electrical properties of on-wafer components up to 110 GHz. Our on-wafer measurements are performed using VSL\u2019s fully automated probing system powered with our autonomous measurement software, redefining RF probing. Our primary calibration substrate establishes SI traceable S-parameter measurements up to 110 GHz, supported with a detailed uncertainty analysis. Feel free to contact us with your on-wafer measurement challenges. <\/p>\n

 <\/p>\n

S-parameter measurements at cryogenic temperatures<\/h4>\n

VSL supports the technological evolution of the quantum supply chain with its state-of-the-art high-frequency characterization facilities operating at 77K and 4K temperatures. VSL can provide calibrated S-parameter measurements of quantum components and circuits mounted with 3.5 mm and 2.92 mm coaxial connectors up to 40 GHz. All cryogenic measurements are supported with detailed uncertainty analysis. <\/p>\n

 <\/p>\n

RF attenuation<\/h4>\n

VSL can provide RF attenuation calibration services for RF attenuator standards operating at dedicated frequency points, including 50 MHz, 100 MHz, and 1 GHz. Attenuation measurements up to 80 dB are supported with an uncertainty of 0.02 dB.[\/vc_column_text][\/vc_column][vc_column width=”1\/6″][\/vc_column][\/vc_row][\/vc_section][vc_section el_class=”dg-padding-mid brand_element_small”][vc_row][vc_column width=”5\/6″ el_class=”dg-padding-none full_width_responsive”][vc_column_text css=””]<\/p>\n
