otherwise, CopyTrig is not available.
Tip
When the current trigger type is “SPI”, performing the copy operation at any time
can quickly apply the current SPI trigger setting (the specified parameters) to SPI
decoding. Then, you can still set the SPI
decoding parameters according to the
introductions below.
3. Set the decoding mode
Press Mode to select the “TimeOut” or “CS” decoding mode.
 TimeOut
When “TimeOut” is selected, you can set the timeout time of SPI decoding.
Press TimeOut and turn the multi-function knob or the inner knob of
the navigation knob to adjust the timeout time at a relatively smaller step or
turn the outer knob of the navigation knob to adjust the timeout time at a
relatively larger step. The adjustable range is from 100 ns to 1 s. The
default is 1 us.
Note: The larger the rotation amplitude of the outer knob of the navigation
knob is, the faster the variation of the value will be. When you need to
adjust the timeout time within a relatively larger range, this function can
help you quickly finish the setting.
 CS
When “CS” is selected, press SS to enter the SS (chip select channel)
setting submenu.
 Set the CS signal
Press Channel and turn the multi-function knob to select CH1 to
CH4.
When a channel (CH1 to CH4) is selected, you can press Threshold
and turn the multi-function knob
to adjust the threshold (the
default is 0 V) of the CS channel. Pressing the multi-function knob
can quickly reset the threshold of the channel to 0 V.
When modifying the threshold of the CS channel, a dotted line
displaying the current threshold level is displayed on the screen (in the
same color as the channel). It disappears in about 2 s after you stop
modifying the threshold.
 Set the level polarity
Press Polarity to set the polarity of the chip select channel to
(positive polarity) or
(negative polarity).
