7.2.1.3 Application Curves
An example pulse measurement using the device is shown in Figure 7-2. The setup follows the example LiDAR system requirements with a 5-ns pulse captured at 800 MSPS. The applied pulse has a rise and fall time of approximately 1 ns. A sub-sampling technique is used to interpolate data points to form an equivalent 25.6 GSPS capture of the pulse for more accurate details and multiple capture averaging is used to suppress noise. A negative DC bias is applied to the ADC to enable use of the full dynamic range of the ADC for unipolar pulses. The pulse is spanning almost the full range of ADC codes. The extracted pulse parameters are given in Table 7-3. The analog front-end is not included in this measurement.
