HP 70810B Lightwave Section, 100 kHz to 22 GHz

The HP 70810B lightwave section is a lightwave receiver module for the HP 70000 modular measurement system (MMS). Consisting of an optical attenuator, broadband photo-detector, microwave preamplifier, and optical power meter, the module combines with HP 70000 series spectrum analyzers.

The lightwave section has a wavelength range of 1200 to 1600 nm, a detected modulation bandwidth of 100 kHz to 22 GHz, and a built-in RF amplifier.

The lightwave section requires an HP 70004 display (recommended) or an HP 70001 mainframe.

Analog power meter display (with the HP 70004 display)
Optical to electrical conversion with variable optical attenuation and amplified RF output

[ Specifications ]

The HP 70810B lightwave section is generally for use with the HP 71400C and 71401C lightwave signal analyzers
or the HP 71210C or 71100C spectrum analyzers.  It can also be used as a standalone optical-to-electrical
converter housed in an HP 70004 display or HP 70001A mainframe.
