I2C Trigger and Serial Decode
Setup for I2C Signals
Setting the I2C (Inter-IC bus) signal entails two steps: connecting the serial data signal (SDA) and serial
clock signal (SCK) to oscilloscope, and specifying the threshold voltage of each input signal.
1.
Press
Shift
and
to enter the
DECODE
function menu as Figure 38 shows.
Figure 38 I2C DECODE Menu
2.
Press the
Decode
F key and select the desired slot (Decode1 or Decode2).
3.
Press the
Protocol
F key and then select
I2C
by turning
Universal Knob
.
4.
Press the
Signal
F key to enter the
SIGNAL
menu as Figure 39 shows.
Figure 39 I2C SIGNAL Menu
5.
Set SCL (I2C’s clock signal):
a.
Press the
SCL
F key to select the channel that is connected to the I2C clock signal.
b.
Press the first
Threshold
F key to set the I2C clock signal’s threshold voltage level by
Universal Knob
. The threshold voltage level is for decoding, and it will be treated as the
trigger voltage level when you set the trigger type to serial.
6.
Set SDA (I2C’s data signal):
a.
Press the
SDA
F key to select the channel that is connected to the I2C data signal.
b.
Press the second
Threshold
F key to set the I2C data signal’s threshold voltage level by
Universal Knob
. The threshold voltage level is for decoding, and it will be treated as the
trigger voltage level when you set the trigger type to serial.
(Note: SDA should keep stable during the whole high clock cycle, otherwise it will be interpreted
as a start or stop condition (data transitioning while the clock is high))
7.
Press the
F key to return previous menu.
I2C Trigger
There are nine kinds of trigger conditions for I2C (Start, Stop, Restart, No Ack, EEPROM, 7 Addr&Data,
10 Addr&Data and Data Length).
