Color Digital oscilloscopes provides long record capture (standard unit has more than 100X the capture time than other oscilloscopes in this class) and unparalleled documentation and connectivity capability. These oscilloscopes offer both two and four channel instruments with bandwidths of 200 MHz, 350 MHz and 500 MHz. It capture waveforms and settings from digital storage oscilloscopes. Color Digital oscilloscopes perform harmonic analysis up to 51 Harmonics. It can store waveforms, pictures, settings and notes. It also exchange waveforms and data with other windows application software. It restore waveforms and settings to digital storage oscilloscopes
