Mixed Signal Oscilloscopes — MSO2000B Series, DPO2000B Series
Triggering on a specific data packet going across an I
2
C bus. The yellow waveform is
clock and the blue waveform is data. A bus waveform provides decoded packet content
including Start, Address, Read/Write, Data, and Stop.
Serial Triggering and A nalysis (Optional)
On a serial bus, a single signal often includes address, control, data, and
clock information. This can make isolating events of interest difficult. The
MSO/DPO20
00B Series offers a robust set of tools for debugging serial
buses with automatic trigger, decode, and search for I
2
C, SPI, CAN, LIN,
and RS-232/422/485/UART.
Serial Triggering
Tr igger on packet content such as start o f packet, specific addresses,
specific data content, unique ident ifiers, etc. on popular serial interfaces
such as I
2
C, SPI, CAN, LIN, and RS-232/422/485/UART.
Bus Display
Provides a higher-level, combined view of the individual signals (clock, data,
chip enable, etc.) that make up your bus, making it easy to identify where
packets begin and end and identifying su bpacket components such as
address, data, identifier, CRC, etc.
Bus Decoding
Tired of having to visually inspect the waveform to count clocks, determine
if each bit is a 1 or a 0, combine bits into bytes, an d determine the
hex valu
e? Let the oscilloscope do it for you! Once you’ve set up
Event table showing decoded Identifier, DLC, DAT A, and CRC for every CAN packet in
alongacquisition.
a bus, the MSO/DPO200 0B Series will decode each packet on the
bus, and display the value in hex, binary, decimal (LIN only), or ASCII
(RS-232/422/485/UART o nly) in the bus waveform.
Event Table
In addition to seeing decoded packet data on the bus waveform itself, you
can view all captured packets in a tabular view much like you would see in
a software listing. Packets are time stamped and listed consecutively with
columns for each component (Address, Data, etc.).
Search
Serial triggering is very useful for isolating the event of interest, b ut once
you’ve captured it and need to analyze the surrounding data, what do
you do? In
the pa s t, users had to manually scroll through the waveform
counting an d converting bits and looking for what cau s ed the event. With
the MSO/DPO2000B Series, you can have the oscilloscope aut omatically
search through the acquired data for user-defined criteria including serial
packet content. Each occurren ce is highlighted by a search mark. Rapid
navigation be tween marks is as simple as pressing the Previous (←)and
Next (→)
buttons on the front panel.
