Apparatus for measuring electric networks. Technician operating a PNA (precision network analyser), which is a member of the VNA (vector network analyser) family of instruments. VNAs are used to measure an electrical network's scattering parameters (S-parameters), which are the properties associated with the reflection and transmission of electrical signals. Photographed at the National Physical Laboratory, in Teddington, UK.
