IMPORTANT In the General tab, you can set the default channel parameters.
Setting Up the Instrument in Drift Mode Setting Up Drift Analysis Parameters 2. Select the General tab.
Setting Up the Instrument in Drift Mode Setting Up Drift Analysis Parameters 3. Under Default channel settings, define the following parameters as needed: OSA Clear the Activate default channel selection, to use the currently defined channel for analysis. This reduces the analysis time by eliminating the peak detection over the complete spectral range. The peaks outside the defined channel list will not be analyzed.
Setting Up the Instrument in Drift Mode Setting Up Drift Analysis Parameters Channel width (GHz or nm): indicates the limit inside which the power values will be considered in the channel. For default channels, the channel width that sets the limits of the channel, should be the same as the channel distance or smaller (channel distance is defined while creating a channel list).
Setting Up the Instrument in Drift Mode Setting Up Drift Analysis Parameters Noise for OSNR: indicates which calculation method to use for OSNR value. Fixed range IEC based (IEC): The IEC method uses the interpolation of noise measured on both sides of the signal to estimate the noise level. The position at which the noise is estimated from the center wavelength is given by the OSNR distance.
Setting Up the Instrument in Drift Mode Setting Up Drift Analysis Parameters Fifth order polynomial fit (Fit): The fifth order polyfit method calculates the noise curve and thus the signal to noise ratio. The OSA will approximate the noise curve using a fifth order polynomial fit. This fit definition relies on fit and exclusion zones. Only the points in the fit zones are used to calculate the fifth order polynomial fit.
Setting Up the Instrument in Drift Mode Setting Up Drift Analysis Parameters 4. Under Global analysis parameters, define the following parameters as needed: OSA Peak detection level (dBm): indicates the minimum power level from where the peak can be considered as a signal. RBW for OSNR (nm): indicates the resolution bandwidth selected for the OSNR calculation. This parameter is generally set to 0.
Setting Up the Instrument in Drift Mode Setting Up Drift Analysis Parameters Wavelength offset (nm): indicates the offset value applied on the wavelength. This does not replace a calibration performed at EXFO, but it can help you temporarily sharpen the specifications if you have determined that, for example, your modules are used beyond the normal allowed use.
