EVM Performance Results
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 the
device under test (DUT) and 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 results.
