C, SPI, CAN or LIN – in terms of interaction with the outside world for
embedded systems, it is safe to say that these are the most commonly used
communication protocols. The R&S®HMO1002 oscilloscopes offer you hardware-
accelerated signal triggering and decoding for all of these protocols. You can
upgrade your instrument via software licence keys with those functions required
to develop your application:
❙ HV110: Analysis of I

C, SPI and UART/RS-232 signals
on analog and logic channels
❙ HV111: Analysis of I

C and UART/RS-232 signals
on all analog channels
❙ HV112: Analysis of CAN and LIN signals
on analog and logic channels
Serial bus trigger types:
