This product has been discontinued
Overview
  • Fast and accurate optoelectronic measurements- The MS4640B VectorStar series VNAs, when calibrated using the MN4765B module, enable error-corrected Transfer Function, Group Delay, and Return Loss measurements of E/O and O/E components and subsystems
  • National Institute of Standards and Technology derived characterization - Magnitude and phase characterization is obtained using a primary standard characterized by NIST and held in the Anritsu Calibration Lab. The magnitude and phase data is provided on a USB drive with the module
  • Temperature Stable - The MN4765B is thermally stabilized to eliminate drift in photodiode performance over temperature
  • Internal Biasing - Accurate bias voltage to the photodiode is maintained internally. An external, multi-country, AC adapter is included for easy operation
  • High Linearity - Linear operating range to +6 dBm for transfer function measurement uncertainties of <0.45 dB @ 50 GHz and <0.7 dB @ 70 GHz (typical specifications for MN4765B-0070)
  • High Responsivity - 0.7 A/W and 0.5 A/W (Typical specification for MN4765B-0070 and -0110 respectively)
The MN4765B is a characterized, unamplified photodiode module. It is used as an optical receiver with the Anritsu MS4640B Series VectorStar VNAs to perform highly accurate and stable optoelectronic measurements of both modulators (E/O) and photoreceivers (O/E).

The MN4765B is the base calibration module part number only. Customers are required to also order an option to configure the bandwidth and wavelength coverage such as the MN4765B-0070 (Option 70), which configures the calibration module for 70 kHz to 70 GHz frequency and 1550 nm wavelength coverage. This option consists of an InGaAs photodiode that converts modulated optical signals to electrical signals, and includes additional circuitry for temperature and bias stability. The photodiode has exceptional bandwidth response to 70 GHz and a typical responsivity of 0.7 A/W. The MN4765B with Option 110 configures the module for 70 kHz to 110 GHz for 1550 nm. It is characterized in both magnitude and phase using a NIST derived calibration standard to 110 GHz.

Option 71 is characterized form 70 kHz to 70 GHz at 1310 nm, while Option 72 is characterized from 70 kHz to 70 GHz at both 1310 and 1550 nm.
