Clock Setting (CLK)

Clock Setting (CLK)
Click or tap the drop-down button of CLK select the desired source of the clock
channel (CH1-CH4) from the drop-down list. If "OFF" is selected, no clock channel is
set, and sampling is performed when a hop occurs to the data of the data channel
during decoding.
Threshold
When the clock signal is an analog channel (CH1-CH4), you need to set a threshold.
Click or tap the input field of Threshold, and then use the pop-up numeric keypad to
set the threshold. You can also use the corresponding multipurpose knob to set the
value. The range of the threshold is related to the current vertical scale and offset.
CLK Edge
When the clock channel is set to an analog channel (CH1-CH4), you can select
"Rising", "Falling", or "Both" in CLK Edge.
• Rising: samples the channel data on the rising edge of the clock.
• Falling: samples the channel data on the falling edge of the clock.
