Iperf3 test method:
Figure 6. Iperf3 test Schematic diagram with SK202
Refer to the figure 6 to connect to the network. The network adapters of two PCs
need the same speed, such as Gigabit Ethernet controller. IP address of PC-A is set to
192.168.10.2, IP address of PC-B is set to 192.168.10.3. Please use at least Cat5e-type
cable for testing
PC-A as a server, run command: iperf3 --server
PC-B as client, run command: iperf3 --udp --bandwidth 1G --client
192.168.10.2 --time 100 --len 63k
IPERF3 will test 100 seconds through UDP protocol with 1G bandwidth, and
there will be BER and jitter result output as the blow picture.
At server side:
At client side:
If you care about the output of iperf3 test, a comparison test is necessary. You can
change the SK202 modules to a RJ45 connector to directly connect two PCs, and use
the same command for comparison test.
