MODEL RELEASED. 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.
