- Abstract:
- An universal coaxial multiplexer for switching one measurement device between several measurement points is described. The coaxial multiplexer consists of independent switch modules (channels), which are controlled via optical fibres. The off-state isolation of multiplexer was measured to be better than -185 dB at 1 kHz. Properties of the multiplexer enable to use it in automation of high precision 2-TP and 4-TP coaxial a.c. bridges or other precise measurement applications.
