2. SPECIFICATIONS
2.1 General
The LE 8682 can take waveform measurements of NTSC/PAL composite video signals.
The measured values can be retrieved using an application installed on a PC or using remote
commands.
2.2 Features
●
Measurement of NTSC or PAL composite video signals
The LE 8682 can measure the burst level, burst frequency, and so on of NTSC or PAL
composite video signals.
●
Automatic self check
The LE 8682 has a feature for calibrating its own measurement levels in the waveform
measurement section.
