3.2.8 Manual Burst Signal 

1.

 

Signal Explanation 

 

Signal Output Pin: 

MANU_BST

 

 

25 bursts. Each burst contains high level and low level.   

 

2.

 

Functions 

Pulse trigger, high sample rate, deep memory 

 

3.

 

Demonstration and Result 

 

Connect the signal output pin MANU_BST and GND to CH1 of the oscilloscope properly using the 
probe.

 

 

Set the time base to 5ms. At this point, the sample rate is 2GSa/s and the memory depth is 
140Mpts. Under single trigger, every burst can be captured as shown in the figure below.
