2.2 EVM Performance
The EVM performance test is performed using a high density DAC bench test board, an Agilent 3458A
digital multimeter, and a PC running LabVIEW software. The EVM board is tested for all codes of 65535,
and the device under test (DUT) is allowed to settle for 1ms 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.
