HP 83485B option 040 module for DCA

Agilent HP 83485B 30 GHz optical / 40 GHz electrical module Plug-in module Compatible with the Agilent 83480A and 86100A/B/C mainframes.

The HP 83485B is an optical/electrical module. It incorporates two measurement channels, one optical 30 GHz Channel and one electrical 40GHz channel . The Electrical Channel also has a reduced-bandwidth setting of 18 GHz for improuved noise performance.


  • 12.4 GHz and 20 GHz Optical Channel
  • 12.4 GHz and 20 GHz Electrical Channel
  • Switchable SDH/SONET filter for transceiver compliance testing
  • Trigger channel input to the mainframe

The integrated optical channel reduces mismatch loss variation by eliminating signal distorting cables and connectors associated with the use of external receivers in order to accurately characterize optical waveforms. The optical channel is calibrated at 1310nm and 1550nm to provide both accurate display of the received optical waveform in optical power units and measurements of the signal average power. In addition, the user cal feature provides for consistent accuracy at any wavelength between 1200nm and 1600nm using a source and power meter. The HP Agilent 83485B optical/electrical plug-in module includes a reference receiver path, similar to the 83485A, for 10 Gb/s transmitter test. Although no industry standards exist for 10 Gb/s testing, the HP 83485B has been designed to meet anticipated future standards.
