CH1-CH4 as clock source. The corresponding logic level can be adjusted when the corresponding signal source is
selected. The way of adjusting is the same with that of trigger level. To avoid the effect of signal noise, it is suggested
that the comparative level should be set in the waveform center area to obtain the accurate captured result. Press the
SCLK EDGE button to set the clock source as rising edge or falling edge.
MOSI Setting: Set Master Output Slave Input Signal
Use this function and enter the MOSI signal setting interface. Press the MOSI Source button to switch any channel
among CH1-CH4 as data source. If MOSI is off, there will be no corresponding data in decoded display. The
corresponding logic level can be adjusted when the corresponding signal source is selected. To avoid the effect of signal
noise, it is suggested that the comparative level should be set in the waveform center area to obtain accurate captured
result. Press the MOSI POLARITY button to set the positive or negative polarity of the chip selection signal. The normal
SPI communication uses the transmission signal with negative polarity.
Condition: Select the Trigger Condition
Use this funtion to switch the trigger condition between CS, Idle, CS&Data, and Idle&Data.
CS will trigger when chip selection enable is effective. Idle is idle trigger. CS&Data will trigger when enable is effective
and the data is correct. Idle&Data will trigger when it is idle and the data is correct.
Condition Setting:

Bit order: Set the bit order to MSB/LSB

Data Setting: Set the comparative values

Bit Width: Set the data bit width need to be compared. The range is 4-32 bits

Bit: Select the bit. The Multipurpose knob can select bit under the data setting interface when a certain
bit is needed to be set. The present selected bit will be highlighted red at the left corner. Note that the
bit you can select is directly related to the byte you set. For example, if 1 byte is selected, the bit you can
select is 0-7.

Data bit: Set every data. The present bit can be set to H/L as required. The present data setting status will
be displayed at the left corner of the screen. The set value display by the method of hexadecimal and
MSB.

All Bits Set: the all bits to the same value, which is helpful for you to set and reset quickly.

to enter the following settings:

Trigger Channel: Press the button to select comparative data channel and switch between MOSI and
MISO.

Frame Length: The bit width of SPI communication is usually different due to the different situation. Now
the Multipurpose knob can make the data bit of the decoding data switch among 4, 8, and 16.
Press the RETURN to return to the first level menu.
Idle Time: Set the idle time value. The Multipurpose knob can set the different overtime value.
Trigger Setting: Set the trigger selection
Press the button TRIGGER SETTING to enter the trigger setting menu. The Trigger Mode can be set to Auto or Normal.
