The Lock-in Instrumentation R&D in the MESEL

Several desktop Lock-in Amplifiers and Analysers and Vector Voltmeters were designed at the Chair (in fact by the research groups existing before the establishment of the Chair) during the years 1977-1990: Vector Voltmeter TB5-78
Vector Voltmeter TB5-79
Vector Voltmeter TB5-80 and TC5-80A
Vector Voltmeter TB5-83
Vector Voltmeter TC5-85
Vector Analyser  TC5-89
Lock-in Oscillator Quadralyser TG5-90
