3M 965AMS User Manual

Pulse Width
1.  Pulse Width allows you to 

select the width of the TDR 

pulse. A longer pulse width 

is required for longer range 

settings.

2.  The tester automatically 

chooses the best pulse 

width for each length 

selected.

3.  You can change the pulse 

width independent of the 

length, but we recommend 

you let the tester select the 

pulse width.

Gain
1.  The Gain control allows 

you to increase the height 

and depth of events.

2.  Higher gain will make 

events look taller or deeper 

on the screen which may 

be helpful in finding small 

events.
