The N7700A Photonic Application Suite Main Package
is distributed free and provides a powerful File Viewer program for analyzing measurement data. It has been designed for sharing measurement results throughout entire development teams or manufacturing groups. The library functions in this package also allow your programs to read and save data in the .omr file format for analysis with the File Viewer.

  • Display and overlay of traces from multiple
    channels and multiple measurement files
  • Scale switching between wavelength and frequency
  • Display of tabular analysis
  • Markers, zooming and analysis features of associated measurement engines
  • File loading, saving and data export
  • Direct launching of Excel and Matlab with data 

The N7700A IL/PDL Engine uses an advanced routine to measure polarization dependent loss and insertion loss spectra on one or multiple channels. The unique single-sweep Mueller Matrix routine reduces measurement time and is very robust against environmental disturbance like fiber movement and temperature drift, while maintaining high IL dynamic range, wavelength accuracy and freedom from bandwidth-limited distortions.

In addition to the measured IL and PDL traces, the Mueller Matrix data can be exported and analyzed to provide the polarization resolved IL traces for the device axes (TE/TM). See brochure for hardware details.

The IL/PDL Engine now supports automated switching of multiple lasers for extended wavelength range and polarization averaged return loss. The COM interface supports automated use. Devices with integrated photodiodes, like phase-shift demodulation receivers can also be measured with Agilent’s special N7745A-E01 with photocurrent inputs in the same setup. The software engine will determine spectra of photocurrent and wavelength responsivity as well as responsivity as TE vs. TM resolution. A bias voltage can also be applied to the photodiodes.
IL/PDL License available for purchase as N7700A-100. The program can be used free for 14 days and a free 60 day evaluation license can also be obtained from the download link.

Available Soon! The Fast Spectral Loss Engine provides insertion loss and power spectra at enhanced repetition rate compared to the basic IL Engine and is a valuable tool for tuning and calibrating devices with near real-time feedback. By making optimal use of the instrument features, repetition rates can be improved by as much as a factor 10. This engine is especially powerful in combination with the 81960A tunable laser which provides bidirectional sweeps and speeds up to 200 nm/s as well. Repetition rates of 1 to 3 scans per second can be attained, depending on the sweep range.

FSIL License available for purchase as N7700A-102. The program can be used free for 14 days and a free 60 day evaluation license can also be obtained from the download link.

The IL Engine performs very accurate swept-wavelength insertion loss measurements. This is a convenient GUI implementation of the widely used 816x Plug&Play MFlambdascan functionality. This can be used with all Agilent continuously swept tunable lasers, 816-series power sensor modules and heads and the N7744A and N7745A power meters. Nolicense required.

The Filter Analysis package performs analysis of measurements from the IL/PDL and IL engines for narrow-band components like filters and multiplexers. Analysis parameters include peak and center wavelength, wavelength offset from ITU grid, IL at ITU wavelength and center wavelength, bandwidth and channel isolation from adjacent and non-adjacent channels. Pass-bands of filters, interleavers and demodulators can be analyzed for PDf and PDλ. A convenient peak search function is also included.
License available for purchase as N7700A-101.

The Polarization Navigator package provides all the tools needed for your work with N778x polarization analysis and control instruments: measurement of Stokes parameters and degree of polarization (DOP) with representation on the Poincaré sphere, PER measurement, long-term monitoring, spike analysis, etc. Various functions for control, switching and scrambling the polarization of optical signals are also provided. The Polarization Navigator also makes robust single-sweep PMD, PDL and IL measurements with the N7788B and a tunable laser. Installation needs the N7700A main package. No license required.
