OH4VNA RU - Remote Unit


The Remote Unit serves as the interface between the 2-port network analyzer and the optical head and is the photonic power supply to the optical head responsible for:

  • conversion of the RF output from port 1 of the VNA to an optical signal sent to the optical head 
  • conversion of the return signal from the optical head to an RF input signal sent to port 2 of the VNA
Frequency Range 500 MHz – 6 GHz
Fiber Optic Channel Configuration 1 Optical Head power-over-fiber channel (forward link)
1 Optical Head RF-over-fiber channel (forward link)
1 Optical Head RF-over-fiber channel (reverse link)
