D8|D9|D10|D11|D12|D13|D14|D15} 
{GROUP1|GROUP2|GROUP3|GROUP4} 
  <digital> is used to select any of channels D0 to D15. The channel label and 
waveform corresponding to the channel selected are displayed in red.   
  <group> is used to select any of user-defined channel groups (GROUP1 to 
GROUP4). All the channel labels and waveforms of the channel group selected are 
displayed in red.   
  When NONE is sent, no channel/channel group will be selected.   
  Only channels or user-defined channel groups currently turned on can be selected. 
Please refer to the :LA:DIGital<n>:DISPlay or :LA:DISPlay command to turn on the 
desired channel or channel group.   
The query returns the current active channel (D0, D1,…or D15), the current active 
channel group (GROUP1, GROUP2, GROUP3, or GROUP4) or NONE. 
:LA:ACTive D3 /*Set the current active channel to D3*/ 
:LA:ACTive?            /*The query returns D3*/
