4-Channel SPO Digital Oscilloscopes

X - DECODE Option Serial Bus decoder

The DOX3000 oscilloscope series come with serial bus Trigger and Decode option for :
I2C - SPI - UART/RS232 - CAN - LIN

I2C serial bus

To analyse an I2C serial bus, we need to connect to the inputs of the oscilloscope the two I2C
signals «

Serial Data SDA

» and «

Serial Clock SCL

», and to set the logic threshold (in Volts)

that defines

the “Low” and “High” levels.

Setting up the oscilloscope to capture and decode the I2C serial bus
signals:

1° Press the «

Decode

» button on the front panel to open the

“

DECODE

”

2° Press the «

Serial

button and select: “

Serial 1

” or “

Serial 2

”

3° Press the «

Decode

» button and select

”

I2C

”

4° Press the «

Signal

» button to open the I2C

“SIGNAL” submenu

5° Press the «

SCL

» button and assign a channel

“CHi” to the “SCL” signal :

6° Press the «

Threshold

» button and use the Universal knob to set the logic threshold for the

SCL signal:

7° Press the «

SDA

» button and assign a channel

“CHj” to the “SDA” signal

8° Press the «

Threshold

» button and use the Universel knob to set the logic threshold for the

SDA signal

Notes :

The decoding process uses the « logic threshold voltage » to determine the « Low » and « High »
levels of the SCL and SDA signals, the logic threshold will become the channel trigger level.

The data should be stable throughout the duration of the « SCL » clock signal high level, a
transition of the « SDA » signal while « SCL » is

“High” may be interpreted as a

Start

(if SDA

changes from « 1 » to « 0 ») or a

Stop

(if SDA changes from « 0 » to « 1 ») condition.
