The A0010A RIN measurement system consists of SYCATUS optical receiver, RIN measurement software, Keysight X-series signal analyzer and digital multimeter.
The optical receiver of A0010A RIN measurement system converts the optical signal from DUT to amplified electrical signal. The noise power density in the signal is measured by the signal analyzer. The photo current of the optical signal is monitored by the digital multimeter. SYCATUS applied a unique technique to calibrate the whole system from the input of the optical receiver to the display of the Signal Analyzer, which enables accurate repeatable RIN measurement.
RIN measurement software and is installed in the signal analyzer. External PC is not required. Optionally the optical attenuator is attachable to the system to control the optical power into the RIN optical receiver. This stabilization contributes further repeatability and the protection of the RIN optical receiver from excessive optical power. RIN measurement software supports RIN-OMA test for IEEE 802.3 standards.
