SPI Trigger
Trigger on the data pattern with specified edge. When using SPI trigger, you need to
specify the SCL, SDA and CS data sources.
Trigger Type:
Press Type to select “SPI”. At this point, the trigger setting information as shown in
the figure below is displayed at the upper right corner of the screen.
Source Selection:
Press SCL, SDA and CS to specify the data sources of SCL, SDA and CS respectively.
CH1-CH4 can be selected as the Trigger Source. The current trigger source is
displayed at the upper right corner of the screen.
Trigger Condition:
Press When to select the desired trigger condition.
 CS: trigger when the CS channel is “H” or “L”. After this trigger condition is
selected, press Mode to select “H” or “L”. Note that CS is valid only when this
condition is selected.
 Timeout: set the minimum time that the clock (SCL) signal must be idle before
the oscilloscope will search for the data (SDA) on which to trigger. After this
trigger condition is selected, press Timeout to set the timeout value and the
range is from 100 ns to 1 s. Note that, at this point, CS is invalid (no display).
Data Line Setting:
Set to trigger after the data channel (SDA) has transmitted data with specified bits
and length.
 Press Bits to select any integer between 4 and 32.
 Press CurrentBit to input the data of the current bit and the range is from 0 to
(the specified value in Bits -1).
 Press Data to set the value of the current bit to H, L or X.
 Press AllBits to set all the bits to the value specified in Data immediately.
