Bus Status

Click or tap the Bus Status on/off switch to enable or disable the bus decoding.

18.1.1 Clock Setting (CLK)

Clock Setting (CLK)

Click or tap the drop-down button of CLK to select from analog channels CH1-CH4 or

digital channels D0-D15 (available only when the digital channel probe is connected).

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

You need to set a threshold when the clock signal is an analog channel (CH1-CH4).

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

You can select "Rising", "Falling", or "Both" in CLK Edge when the clock channel is

set to an analog channel (CH1-CH4).

• Rising: samples the channel data on the rising edge of the clock.

• Falling: samples the channel data on the falling edge of the clock.

• Both: samples the channel data on the rising edge or the falling edge of the

clock.
