86100C TDT automatic measurement

Question asked by tim.le on Mar 22, 2011
Dear Miss/Sir,

I have question about 86100C TDT automatic measurement.

I am working on TDT automatic testing using Visual Basic.  the instrument is Agilent 86100C with 2 pcs 54754 sampling head.

It works well when I move horizontal position by button. For example, the current horizontal position is 40 ns, I manual change horizontal postion  from 40 ns to 50 ns. then I can see rise/fall edge trace.

But when I tried to change horizontal position from 40 ns to 50 ns by GPIB commmand. then I can NOT see correct trace on screen that tail of trace is missed.

Could you teach me how to fix this problem ? Appreciate in your helps.
