The VectorStar ME7848A opto-electronic network analyzer (ONA) provides a modular approach to optical measurements of O/E, E/O, and O/O devices operating at 850, 1310, and 1550 nm wavelengths. There are two configurations available: the VectorStar ME7848A-100 series includes the MN4765B O/E calibration module and the VectorStar ME7848A-200 series adds the MN4775A E/O converter.
The VectorStar ME7848A-200 series provides the ability to quickly switch between O/E, E/O, and O/O measurements with specified traceable measurements established by the MN4765B O/E calibration module.
The VectorStar ME7848A ONA can be easily modified to different wavelengths by adding the appropriate MN4775A E/O converter and MN4765B O/E calibration detector. The VectorStar ME7838A-100 series can be upgraded to a 200 series by including the appropriate MN4775A E/O converter.
Measurement Capabilities
With the addition of the two modulators, VectorStar, along with a 110 GHz O/E photodetector, can make the following measurements. The inherent advantages that we had on the 70 GHz system are still applicable to the 110 GHz system, namely upgradability, flexibility of making opto-electronic and E/E measurements, and NIST traceability on the reference calibration photodetector.

Electrical to Optical Converter MN4775A
The MN4775A is an electrical to optical converter that uses an RF input signal to intensity modulate an internal laser. The E/O converter is used in conjunction with the VectorStar MS464xB or the Shockline MS4652xB series VNAs and the MN4765B optical to electrical (O/E) converter to perform highly accurate and stable optoelectronic measurements of both modulators (E/O) and photoreceivers (O/E). The MN4775A includes a laser, an optical Mach-Zehnder intensity modulator and a variable optical attenuator to control its output power. Internal circuitry provides various power and modulation configurations as well as stabilizes overall performance.
