KEYSIGHT N7781C 1240 to 1650 nm Polarization Analyzer

The Keysight N7781C Polarization Analyzer is a compact high-speed polarization analyzer that provides comprehensive capabilities for analyzing polarization properties of optical signals. This includes representation of the state of polarization (SOP) on the Poincaré sphere (Stokes parameter). The on-board algorithms together with the on-board calibration data ensure highly accurate operation across a broad wavelength range. Its real time measurement capability of 1 M samples/s, the instrument is well suited for analyzing disturbed and fluctuating signals as well as for control applications requiring real time feedback of polarization information. It comes in a compact form factor of just one rack height unit, with LAN and USB interfaces.

Bit Error Ratio (BER)
Bit Error Ratio (BER) is the ratio of errors caused by the number of bits in a data stream that have been altered due to noise, interference, distoriton or bit synchronization errors.

Flatness
Variation of insertion loss on the passband of an optical device.

Polarization Dependent Loss (PDL)
Polarization Dependent Loss is the difference between the maximum and minimum values of loss due to the variation of the polarization states of light propagating through a device. PDL is expressed in decibels. Calculated by; PDL = 10 log10 (Ep/Es), where EP and ES are the measured diffraction efficiencies for P- and S-plane polarized incident light, respectively.

Return Loss (RL)
Return Loss (RL) is the ratio of the incident power to the reflected power expressed in dB. RL = 10log (Pin/Pback)

Wavelength Resolution
Wavelength Resolution is the smallest possible displayed wavelength increment/decrement.
