Hameg HOO12 protocol analysis

Apart from functions like parameters with statistics, Hameg Instruments provides the option HOO12, which allows triggering and decoding of CAN and LIN protocols. Combined with the options HOO10/11 for I²C, SPI and UART/RS232, Hameg provides users in the automotive, medical, aircraft and automation industries with a complete solution for the development of embedded systems.

The HMO series oscilloscopes decode 2 CAN buses simultaneously, hence they are especially useful for system designers. A table presentation for the decoded values of all protocols has been implemented which presents all information of a message telegram in one line. Special trigger properties allow the precise isolation of single messages. For individual measuring tasks, the 2/4 analog channels and 8/16 digital channels can be annotated. Users who are mainly interested in the protocol level may even use the least expensive oscilloscope of the HMO series, the 70 MHz HMO722 and the CAN option to analyse this bus.

In accordance with the protocol analysis of the CAN bus, Hameg has a 200 MHz differential probe HZO40 and a 800 MHz differential probe HZO41. Both have good electrical properties (3.5 pF resp. 1 pF input capacity, 1 MΩ resp. 200 kΩ input resistance), a variety of practical accessories and customisable power supply options. Combined with the respective HMO series oscilloscope (or any other one), many measurements on differential signals are possible without loading the signal.
