Micsig MS320IT

Main advantages of MS300IT series are isolated inputs, Serial-Bus Decoder for UART,LIN,CAN,SPI,I2C and continuous oscilloscope measurement record. Handheld oscilloscopes Micsig stand on first place at its price segment. MS300 series offers great features of professional tools for an incredible price. Scopmeter MS320IT offers bandwidth 200MHz with sampling rate 1GSa/s. The measurement results, compared to competing products in this price range, are more than wonderful. Micsig MS300IT offers huge LCD Touch screen 5.7", 640*480 in addition.

Isolated Inputs

Isolated inputs are great choice whenever there is a need of multi channel differential measurement, for example in switching supplies, or measurement on mains supply side. Micsig offers maximum input voltage with respect to ground 1000V CAT Ⅱ and 600V CAT Ⅲ.

Serial Bus Decoder

Serial Bus Decoder is powerfull tool for serial communication debugging. Recognized serial protocols are UART, LIN, CAN, SPI and I2C. Decoder can be fully configured including various trigger conditions based either on the state of the bus or on data. Decoder has two operating modes - graphical mode and text mode. See demostrations for more details.
