The Data Integrity (DI) allows you to check data integrity of
transmitted/received packets. To enable the data integrity check of transmitted
packets, check the check box in the Transmit field. To enable the data integrity
check of received packets, check the check box in the Receive field.
When this function is enabled and the transmitting packet flow reaches
wirespeed, a 1 byte-time of frame gap will be inserted after a certain amount of
packets are transmitted. This can reduce packet loss caused by crystal
frequency differentials between DUT and test instrument. Enabling Elongated
Frame Gap can compensate crystal frequency differentials by around 30 ppm as
simulation.
This function is specially designed for XM-RM881. Enable this function to
ensure the packets not of an integer multiple of 4 bytes to approximate the wire
speed. Or these packets may fail to reach the wire speed.
