PASS/FAIL AUTO TEST FUNCTION
|
|
The waveform can automatically be judged to PASS or FAIL against specified conditions.
Using Template function upper and/or lower limits for the assessment can be set
and measured waveform can automatically be compared.
It is an effective way to reduce time and human error in assessment,
especially for production line tests.
The template data can be created and stored in the AQ6370B.
It can be edited using a spread sheet on an external computer as well.

13 AUTO ANALYSIS FUNCTIONS |
|
|
Thirteen types of built-in analysis functions for popular applications
can be selected by using Analysis function key on front panel
or by mouse operation.
The functions automatically perform designated analyses and provide results.
The results can be saved in a storage device.
· WDM analysis (OSNR)
· WDM-NF analysis (EDFA)
· DFB-LD analysis
· Filter analysis, etc.

Analysis Parameter Window
All parameters for an individual analysis are displayed in a dialog box for easy setup.

7 TRACES & CALCULATION FUNCTIONS |
|
|
|
The AQ6370B has seven individual traces for measurement data.
Some traces can be used for calculations (two-trace subtraction and addition),
MAX/MIN hold, averaging, and curve fitting.
|
|
Enhanced Curve Fit function
The Curve fit function is an approximation technique
to exclude an influence of noise and/or signal overlapping on the waveform.
Curve fit method can be chosen from Gaussian, Lorenz, 3rd Poly, 4th Poly, and 5th Poly.
Curve fit can be applied to an individual trace.
Fitting area can be set by line markers (L1 and L2).
|
|
- Analysis mode
When WDM or WDM-NF analysis is executed, one of the curve fit methods
is used for a baseline measurement.
The curve fit method can be specified in the parameter window of each analysis.
|
|
- Example of curve fitting in selected areas
Noise level of amplified WDM signal can be estimated by using the curve fit in selected areas,
even if noise between signals cannot be seen due to a limit of signal separation performance.
|
|
- Marker fitting
The fitting curve can also be applied to the marker positions set by user.
For example, this can be used to measure a modulated signal spectrum.
