The LV 7700 is capable of displaying the monitor waveform, image, and other data of HD-SDI and SD-SDI signals on an external display (SD-SDI signals only on the LV 7720). Display items include waveform monitor, vectorscope, audio monitor, simple picture display, as well as multi display on which these items can be arranged on a single screen. Its 1U half rack size reduces space consumption in broadcasting installations, etc. In addition, complete digital processing of SDI signals enables highly accurate measurements. It is also suitable as a monitoring device that monitors signals and detect errors via the network through the support of SNMP.
