Abstract :
An assembly of a light emitting diode, optical fibre and photodetector is proposed for isolating the channels in radio frequency dual channel measurement systems. The isolation effects are verified in the experimental setup of a 10-100 MHz attenuation measurement system and satisfactory results are reported
