3 Test Procedure

Test procedure used to obtain LMK0033x's PCIe compliance report results is as follows:

  1. After powering up the device, the differential outputs are connected directly to an oscilloscope for time domain measurements, or to a PNA through a balun for frequency domain measurements.
  2. An output trace file is captured from the PNA or oscilloscope. Note that the oscilloscope capture requires both the positive and negative traces, so two output trace files from the oscilloscope are required.
  3. The file/files generated is/are run through TI's PCIe Compliance Tool (Section 4 contains more information about this tool).
