Description
Turns on and off Rapid Eye data acquisition, which significantly reduces the time required to acquire the waveform samples. Rapid Eye employs several techniques that improve measurement efficiency. Use the :INTerval child command to select the number of UI (Unit Intervals) to acquire the data from. The database is expanded as required, while keeping the displayed eye (usually 1.6 UIs) unchanged. All acquired samples, even those residing in an incomplete UI area, are properly applied. For example, after an Auto Scale, 1.6 UIs are displayed and 40% of the samples occur before or after the UI area. With Rapid Eye on, these sample points will now be recorded and included in their proper position within the UI. Use the :TIMebase:BRATe command to enter the symbol rate.
When multiple eye diagrams are displayed, use the :ALIGn child command to enable the Auto Scale command (:SYSTem:AUToscale) to align the eyes using software delay. This is especially useful if you are using multiple DCA-M Sampling Oscilloscopes or a DCA-M with an N1000A.
Rapid Eye requires FlexDca be placed in Eye/Mask mode without pattern locking.
