MODEL V500 Fiber Optic 
Analog Receiver

The Optiphase V500 Fiber Optic Analog Receiver Leads the Field in both Hand Held and Lab Bench Optical Receivers. It offers exceptionally high performance combined with an operational feature set which puts it in a class by itself. Its highly ergonomic layout and industry standard interfaces will have Rubes and Rocket Scientists alike up and running in the field or lab in a matter of minutes. Compare the V500 with what you currently use. At $950 You can't afford not to have one or more of these units. Feature Highlights Include.

• Frequency Response 500 kHz
