Test 2.1 Jitter Tolerance Test
The purpose of this test is to verify that the jitter tolerance test is within specification limits . To do this the PeRT
3
output must first be calibrat ed. Specified previously, as of the release of this version of QP HY-USB3-Tx -Rx, the
receiver test calibration portion of the specification has not yet been finalized. Once, the PeRT
3
output is
calibrated, the PeRT
3
sets the PUT into loopback mode and performs the jitter tolerance test on the 8 required
points: 50MHz, 33MHz, 20MHz, 10MHz, 4.9MHz, 2MHz, 1MHz and 500kHz.
