surveyed. More data (14div) of pre-trigger and 1s delayed trigger can be 
surveyed by adjusting the horizontal 
 knob. 
This feature is very useful to study the events that led up to the trigger point. 
Everything on the right of the trigger point is called post-trigger information. The 
delay range (pre-trigger and post-trigger information) depends on the sweep 
speed selected. 
 
3.  Adjustable trigger sensitivity 
To avoid the influence of noise from the physical world, and get the stable trigger, 
the trigger circuit has adopted Stickiness. In DS1000B series, the stickiness is 
adjustable from 0.1div-1.0div, which means when it sets to 1.0div; the trigger 
circuit will not affect any signal with peak-peak amplitude less than 1.0div, so as 
to avoid the influence of the noise.
