Main features and technical specifications for the 9 /125 20 GHz optical zoom • optical channel wavelength range :1000-1600 nm • Typical rms noise : 8 μW (12.4 GHz of bandwidth ), 15 μW (20 GHz Bandwidth ) • reference receiver functions (155 Mb / s, 622 Mb / s, 2.488 Gb / s, 0.622/2.488 Gb / s or 2.488/9.953 Gb / s) using a 3.5 mm male input 20 GHz electrical channel • Typical rms noise : 0.25 mV (12.4 GHz bandwidth ), 0.5 mV (20 GHz of bandwidth ) • maximum input signal : ± 2 Vdc compatibility • 86100A/B/C Infiniium DCA / DCA-J host Description Agilent 86105A has two measurement channels : an optical channel and an electrical channel . Each channel has two bandwidth settings to choose from. In the 12.4 GHz low- bandwidth mode , the oscilloscope has an extremely good noise performance ; while in the 20 GHz mode , the oscilloscope can provide a higher fidelity of high-speed signals. Also has an optical path of the switchable filter for forming calibrated SDH / SONET reference receiver . Integrated optical channel abandoned when using an external receiver signal distortion required cables and connectors that can accurately characterize optical waveform , thereby reducing the mismatch loss variation . This optical path is calibrated on 1310 nm and 1550 nm wavelengths , the optical power unit can accurately display the received signal waveform and the average optical power measurements . Agilent provides support rate 155,622,2488 or 9953 Mb / s conformance testing switchable filter. Electrical measurement channels can be used to measure the slip signals, the receiver performance evaluation transceiver tests , measurements and other common measurements using Agilent 's various external optical receiver .
