In additional, you can also modify the settings of Width, Bit X and CH

manually.

Note:

This function is only applicable to mixed signal digital oscilloscopes with

digital channels.

4. Data Line Setting

Set the bus width

Press Width to set the data width of the parallel bus namely the number of

bits per frame. The default is 8 and the range is from 1 to 16.

Specify data channel for each bit.

Press Bit X to select the bit that needs to specify a channel. Press CH to

specify a channel source from CH1-CH4 or D0-D15.

5. Analog Channel Threshold Setting

To judge logic "1" and logic "0" of the buses, you need to set a threshold for

each analog channel (CH1-CH4). When the signal amplitude is greater than the

preset value, it is considered as "1"; otherwise "0".

Press MATHDecode OptionsAuto Thre. to turn on or off the auto
threshold function. When auto threshold is turned on, the middle value of the
channel waveform is defined as the digital threshold level. When auto threshold
is turned off, you can press Thre.Set to enter the threshold setting menu. Press
CH1, CH2, CH3 and CH4 respectively and use

to set the threshold of each

channel. Press 50% and set the current threshold to 50% of the current
waveform trace manually.
