➢  Press  Bytes,  then  rotate  the  multifunction  knob    or  use  the  pop-up 
numeric keypad to set the length of the data. Its range is from 1 to 5. 
➢  Press More → Addr Bits, and rotate the multifunction knob    to select 
the desired address bits. Then press down the knob to select it. You can 
also press Addr Bits continuously or enable the touch screen to select it. 
The available address bits are "7 Bits", "8 Bits", and "10 Bits". 
⚫  A&D: the oscilloscope searches for the specified address and data at the same 
time, then triggers when both the address and data meet the conditions. After 
this  trigger  condition  is  selected,  you  need  to  set  Bit  X,  Bytes,  Addr  Bits, 
Address, and Direction menu items. For setting methods, refer to descriptions 
in "Address" and "Data" trigger conditions.
