2.2 EVM Performance
PCB Design and Performance
Figure 8. Drill Drawing
The EVM performance test is performed using a high-density DAC bench test board, an Agilent 3458A
digital multimeter, and a PC running the LabVIEW™ software. The EVM board is tested for all codes of
65535, and the DUT is allowed to settle for 1 ms before the meter is read. This process is repeated for all
codes to generate the measurements for INL and DNL.
Figure 9 shows the INL and DNL characteristic plots.
