The HD TAB 9 has an "F" coaxial input to provide RF measurements. There are also ASI IN and OUT BNC connectors for looking at a transport stream. An optical/electrical converter to carry out power and attenuation measurements is optional. There is a common interface slot and an HDMI output (useful for connection to a monitor, or video projector, to reproduce what is being shown on the display). Two 3.5mm AV IN and AV OUT jacks with stereo audio function like the HDMI OUT, but only supplies a SD picture. There are two USB sockets for firmware upgrades, memory plan management and the recording of screenshots. On the right side, there are two RJ-45 sockets for TS input over IP (optional) and LAN Ethernet. The IPTV option provides an input for a transport stream over IP which will de-encapsulate the contents of the IP stream, carry out quality measurements and decode the services transported.
