Capture App
Port: Specify a port number to capture only
traffic from that UDP or TCP port. For example,
select port 80 to capture HTTP traffic only.
NOT: Touch the toggle to enable this setting,
which directs the EtherScope NOT to capture
the values you have entered in the filters above.
For example, if you have set up a filter to
capture traffic to and from IP 10.250.0.70 on
Port 80 and you enable NOT, all traffic is
captured except traffic to and from 10.250.0.70
on port 80.

MHz width.

packets going to or from the target device.
