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/DPO4000B Series will decode each packet on the bus, and display
the value in hex, binary, decimal (USB, Ethernet, MIL-STD-1553, LIN, and
FlexRay only), signed decimal (I
2
S/LJ/RJ/TDM only), or ASCII (USB,
Ethernet, and 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.). You can save the event
table data in .csv format.

Search (serial triggering)
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. 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.
Power analysis (optional)
Ever increasing consumer demand for longer battery-life devices and for
green solutions that consume less power require power-supply designers to
characterize and minimize switching losses to improve efficiency. In
addition, the supply’s power levels, output purity, and harmonic feedback
into the power line must be characterized to comply with national and
regional power quality standards. Historically, making these and many
other power measurements on an oscilloscope has been a long, manual,
and tedious process. The optional power analysis tools greatly simplify
these tasks, enabling quick and accurate analysis of power quality,
switching loss, harmonics, safe operating area (SOA), modulation, ripple,
and slew rate (di/dt, dv/dt). Completely integrated into the oscilloscope, the
power analysis tools provide automated, repeatable power measurements
with a touch of a button; no external PC or complex software setup is
required. The optional power analysis functionality is offered free for a 30-
day trial period. This free trial period starts automatically when the
instrument is powered on for the first time.
