Decode

The Most Intuitive Decode

Advanced software algorithms

decon struct the waveform into

protocol information, then overlay

the decoded data on the waveform.

Decode information condenses

or expands depending on the

timebase/zoom ratio setting, so

understanding messages is easy.

Various sections of the protocol

are color-coded to make it easy

to understand, especially for users

new to I2C, SPI, UART, and RS-232

serial data. The decode operation is

fast—even with long acquisitions.

The user can choose to decode into

Hex, Binary, or ASCII formats.

Teledyne LeCroy’s decode algorithms

allow the CLOCK signal to be input to

the external channel, which saves

valuable channels for other signals.

Or, if the CLOCK signal is input to

a channel, it can be turned OFF as

desired to reduce display clutter.

Powerful Conditional

Data Triggering

Completely isolate speciﬁc I2C,

SPI, UART, or RS-232 message

events for better understanding

and debug. Use a conditional DATA

trigger to select a range of DATA

values to trigger on, not just a single

DATA value. Oftentimes, I2C utilizes

DATA bytes to specify sub-addresses

for accessing memory locations in

EEPROMs. Condi tional DATA trigger

allows triggering on a range of DATA

bytes that correspond to reads or

writes to speciﬁc sub-address memory

blocks in the EEPROM. It can also

aid in monitoring DATA outputs from

I2C-based sensors, such as analog-to-

digital con verters, and triggering

when DATA is outside a safe operating

range. In both cases, verifying proper

operation becomes a simple task.

Of course, all the basic I2C and SPI

triggering capability you would expect

is also included.

Full UART and RS-232

Capability and Customization

Complete support for any conﬁgura-

tion of UART and standard RS-232.

Generic UART is commonly used

as the backbone for proprietary

protocols, and the ﬂexible setup

conﬁguration allows deﬁnition to meet

your exact need.

Key Features

• I2C, SPI, UART and RS-232

Trigger and Decode

• Color-coded decode overlaid

on the waveform is intuitive

and easy to read

•

Powerful and ﬂexible

conditional DATA triggering

(=, not =, >, >=, <, <=, <>, in

range, out of range).

• Hex, Binary or ASCII decoding

• Decode information expands

as the timebase is adjusted

or zoomed

• Convenient table display with

quick “zoom to message”

capability

• Quick search capability for

speciﬁc messages

• Set an ACK condition (ACK,

NO ACK, Don’t Care) in all

frame trigger setups (I2C)

• Decode does not require clock

trace to be displayed (I2C, SPI)

• Supports UART address (9-bit)

Byte triggering

• Supports trigger and decode

of user deﬁned proprietary

protocols based on a UART

backbone

Color-coded overlaid protocol decode makes it easy to understand your serial data messages.

POWERFUL TRIGGERING, INTUITIVE DECODING

Flexible Triggering

I2C, SPI, and UART all have special

use cases and the Teledyne LeCroy

Trigger and Decode solutions address

these cases. The I2C trigger can be

conﬁgured for 7 or 10-bit addressing

with out without inclusion of the R/W

bit. The SPI trigger can be conﬁgured

for a range of CPOL and CPHA set-

tings as well as the Simpliﬁed SPI

protocol. With the UART trigger 8 and

9-bit (8+1) formats are supported.

Convenient Table Display

Summarizes Results

Turn your oscilloscope into a protocol

analyzer with the Table display

of protocol information. Custom

conﬁgure the Table to display

only the infor mation you want, and

export Table data to an Excel ﬁle.

Touch a message in the table and

auto matically zoom for detail. In

all cases, the Table never obscures

your waveform data.

Search and Zoom

I2C, SPI, UART, and RS-232

messages can be quickly located

by search ing on Address (I2C) or

DATA (I2C, SPI, UART, RS-232).

Pressing an arrow button advances

the single zoomed message view

one message to the right or left

of the current message. Search through long record of decoded data by entering the message

or address you are looking for and clicking the right or left search

arrows.

Display your values in an easy-to-understand table. Touch a row to zoom, or export to

Excel with one button push.

Simultaneously decode up to 4 serial data buses. When using the MSO option on

WaveRunner Xi or WaveSurfer Xs the digital inputs D0, D1, D2, etc. can be used as

the source for a serial data trigger and decode.
