Description: The HP Agilent 83485A is a reconditioned Optical/Electrical Plug-In Module that incorporates two measurement channels, one optical and one electrical.

Product Specs:
Each channel has two selectable bandwidth settings. In the lower bandwidth modes of 12.4GHz, oscilloscope noise performance is excellent, while the 20GHz mode allows greater fidelity for high speed signals.
The unit also is a calibrated SONET/SDH reference receiver that is measured to comply to ITU-TS (formerly CCITT) G.957 and Bellcore GR-253-CORE frequency response requirements for transmitter compliance testing.
