.
The 
Memory Usage is set as follows:
•   
1 x 36 cycles: upon trigger, the entire buffer is filled with 36 cycles of data
•    
2 x 18 cycles: 2 separate 18-cycle buffers are created and each is filled 
upon a trigger
•    
3 x 12 cycles: 3 separate 12 cycle buffers are created and each is filled 
upon a trigger
If the 
Trigger Mode is set to One-Shot, then the trace memory is triggered once per 
buffer; if it is set to 
Retrigger, then it automatically retriggers and overwrites the 
previous data.
The 
Trigger Delay delays the trigger by the number of cycles specified. 
The 
VOLTAGE, CURRENT, and SWITCH INPUTS selections are the parameters and 
levels that are used to trigger the trace memory.
