During this summer Ventspils University of Applied Sciences (VUAS) performed free testing services for local SME called Cryogenic and Vacuum Systems (CVS) in the framework of project “Laboratory network for testing, characterisation and conformity assessment of electronic products developed by SMEs” (abbreviation – TEST-4-SME).
The aim of the testing is for the laboratory to iteratively develop and improve testing procedures, quality and efficiency of testing in order to speed up the process of product development for electronic SMEs. In total, testing was performed 3 times – on 2nd of July, 23rd of July and 5th of August.
During these tests dedicated Vector Network Analyser (VNA) in the possession of VUAS was calibrated and used to measure S parameters of radiofrequency (RF) equipment like RF cable, RF low pass filter and RF attenuator according to EIA-364-108 standard. In total all 4 S parameters were measured. These include Input Reflection coefficient (S11), Forward transmission (insertion) gain (S21), Reverse transmission (insertion) gain (S12) and Output Reflection coefficient (S22).
After each testing a testing report was compiled and delivered to SME that summarized all measured parameters. After each testing the measurement procedure was improved that yielded better quality and speed of testing. Future testing is planned to further improve testing capabilities of VUAS testing facility.
