Managing Measurement Parameters
To set the histogram window width for NRZ and RZ formats:
1. From the main window, select the Measure menu.
2. Select Window width.
3. Enter the desired values for the window.
Note: In the case of short RZ pulses with a low duty cycle, you must decrease the
RZ window width to a small value. For example, if the duty cycle is only
10%, EXFO recommends that the window width is set to 1 %; if the duty
cycle is only 1 %, the window width should be set to 0.1%.
4. Click OK to close the window.
To remove all measurements from the window:
From the main window, select the Measure menu, then Remove all.
