|
To configure the FPGA design to acquire samples in SETS, the GUI has to send the necessary parameters using a protocol.
|
|
|
This is done as soon as the user leaves the time base in which the ADCs are able to sample at real time.
|
|
|
Because of the selected ADCs, the maximum real time sample rate is 2.5 MSa/s. This sample rate is used, if the user selects 20 μs/div as time base.
|
|
|
A time base smaller than this will require a higher sample rate which is only achievable using the SETS mode.
|
|
|
After receiving the necessary parameters from the GUI, the FPGA starts capturing the first samples of the measured signal.
|
|
|
The process of capturing the first sample in relation to the timing behavior of the ADC is illustrated in Figure 1.
