c. Press the Threshold softkey to set the SPI MISO signal’s threshold voltage
level by Universal Knob. The threshold voltage level is for decoding, and it
will be used as the trigger voltage level when the trigger type is set to
serial.
d. Press softkey to return previous menu.

CLK
Timeout
If the time between two edges of clock signal is less
than (or equal to) the value of timeout, the signal
between the two edges is treated as a frame. The
range of clock timeout is 100 ns-5 ms. This setting is
suitable for case where CS signal is not connected,
or the number of oscilloscope channels is
insufficient (such as two-channel oscilloscopes).
