The Sync Mode in Logic Analyzer of Analog Discovery & Digital Discovery


BDS

Question

In the sync mode of the logic analyzer of both the Analog Discovery Kit and Digital Discovery Kit I am getting the following options:

   * Samples

   * Rate

    * Enable

    * Edge with which to sample

 

What is the purpose of "rate" here. Shouldn't the sampling happen with the "edge with which to sample". I am seeing that the signals are sampled at the "Rate" rather than with the "edge with which to sample". Attached is the snapshot where it ignores DIO 0 rising edge and samples at 400 kHz. When I change rate to 1 MHz it samples at 1 MHz. When I export the data I see that the values are 1us apart when Rate=1 MHz. I am using Waveforms 3.14.3 64-bit Qt5.9.7 Windows 10 (10.0) version. Am I doing something wrong?
