2.2 EVM Performance
PCB Design and Performance
Figure 6. Drill Drawing
The EVM performance test is carried out using a high-density DAC bench test board, an Agilent 3458A
digital multimeter, and a personal computer running the LabVIEW™ software. The EVM board is tested for
all codes of 65535, and the device under test (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 7 shows the INL and DNL characteristic plots.
