inserting and/or removing, by the adapter, one or more delay characters between the two consecutive data units based on a timing jitter of a clock signal of a first transmission line for transmitting data units of the plurality of data units according to the first transmission rate and/or a second transmission line for transmitting data units of the plurality of data units according to the second transmission rate.
11. The method of claim 8 , further comprising:
determining, by the adapter, a delay value based on the at least one delay character received.
12. The method of claim 8 , wherein a data unit of the plurality of data units is a data frame or a data packet.
13. A method for transmission rate adaptation of one or more data units performed by a test system comprising an adapter being located between a test device and a device under test, the method comprising:
receiving, by the adapter comprising an adaptation circuitry, a plurality of data units according to a second transmission rate;
inserting, by the adapter, one or more delay characters between two consecutive data units based on a timing jitter of a clock signal of a first transmission line for transmitting data units of the plurality of data units according to a first transmission rate and/or a second transmission line for transmitting data units of the plurality of data units according to the second transmission rate; and
transmitting, by the adapter, each data unit of the plurality of data units received according to the first transmission rate and the one or more delay characters separating the two consecutive data units to the test device.
