The "Swiss Army Knife" for the network engineer is often called such devices. Two representatives of this family are e.g. our LanExpert devices. They combine all essential test functions for an Ethernet network in a single compact, robust and very easy to use handheld device. The device is easy to operate via a color touch screen and combines complete test and analysis functions in a portable, robust device.
Test options include simple basic cable testing, such as determining wiring diagram, cable length and Power over Ethernet load capability. On the active page you will find the simple network tests, which follow up connections in the network by means of ping, trace route and hub activation and enable the recording of network devices such as switches and routers and terminal devices.
The higher-value test options include VoIP analysis of operating data and VoIP quality, packet capture and recording for subsequent (external) analysis with WireShark. Graphical representation of network statistics supports protocol analysis. To top it all off, these devices also contain traffic generators to even perform stress tests according to RFC 2544.
