Chapter 4 Field Bus Measurements Introduction Fieldbuses are bi-directional, digital, serial control networks used in process control and industrial automation. The test tool can indicate the status of the following aspects of the OSI model Physical Layer: • Voltage levels (bias, high level, low level) • Bit width - baud rate • Rise and fall time • Distortion Moreover the test tool can show the bus signal waveform in the Eye-pattern mode, see page 4-7. The test tool operates in full automatic (ranging and triggering) mode. Test limits are preset, but can be changed, see page 4-8. For supported bus types and protocols see Chapter 10, section Fieldbus Measurements. Note You can perform resistance measurements and capacitance measurements using the Scope/Meter mode. 4-1
