DAC in the foreground trace (yellow) which has removed all frequencies above 5.5 kHz.

FilterVu also captures and displays high-frequency glitches up to the full bandwidth of the

oscilloscope in the background trace (orange).

Serial triggering analysis (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/DPO2000B Series offers a robust set of tools for debugging serial

and RS-232/422/485/UART.

Serial triggering

Trigger on packet content such as start of packet, specific addresses,

specific data content, unique identifiers, etc. on popular serial interfaces

clock and the blue waveform is data. A bus waveform provides decoded packet content

including Start, Address, Read/Write, Data, and Stop.

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 subpacket 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, and determine the hex value?

Let the oscilloscope do it for you! Once you've set up a bus, the MSO/

DPO2000B 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

only) 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, but once

you've captured it and need to analyze the surrounding data, what do you

do? In the past, users had to manually scroll through the waveform counting

and converting bits and looking for what caused the event. With the MSO/

DPO2000B Series, you can have the oscilloscope automatically search

through the acquired data for user-defined criteria including serial packet

content. Each occurrence is highlighted by a search mark. Rapid navigation

between marks is as simple as pressing the Previous (←) and Next (→)

buttons on the front panel.
