Chapter 8 Protocol Decoding RIGOL

MSO4000/DS4000 User’s Guide 8-15

I2C Decoding (Option)

I2C serial bus consists of the clock line (SCLK) and the data line (SDA). The

oscilloscope samples the channel data on the rising edge of the clock signal (if the

source channel is an analog channel, the system will judge each data point as logic

“1” or logic “0” according to the threshold level set).

Press Decode1  Decode, turn the multi-function knob to select “I2C” and

press the knob. You can press Decode continuously to switch to “I2C”.

Set I2C decoding (take Decode1 as an example):

1. Turn on or off the Decode1

Press BusStatus to turn the Decode1 display on or off. You can also press

Decode1 to switch the current on/off status of the Decode1 display. When the

bus display is turned on, the interface is as shown in Figure 8-4.

2. Quickly apply the current I2C trigger setting to I2C decoding

If the current trigger type of the trigger system is I2C, press CopyTrig to copy

the current clock signal and data signal settings (SCL and SDA) of I2C trigger

setting and apply them to the I2C decoding function (SCLK and SDA). If the

source channel is an analog channel, the threshold level setting will also be

copied.

Note: The copy function is only available when the current trigger type is “I2C”;

otherwise, CopyTrig is not available.

Tip

When the current trigger type is “I2C”, performing the copy operation at any time

can quickly apply the current I2C trigger setting (the specified parameters) to I2C

decoding. Then, you can still set the I2C decoding parameters according to the

introductions below.
