axe) is displayed on the approx. 600 screen pixels. But the spectrum could have 25600 lines and then 42 lines
is displayed in one pixel line ( 42=25600/600). This number of lines in one graph pixel is different for other total
line number and used zoom. In the older VA4 version we used the cursor movement procedure by lines. It
means that the cursor moves inside one pixel without any real move on the screen. The users complained about
it. In the version 2 we have used another procedure. The cursor moves by pixels, not by lines. In each pixel is
hidden more lines and the cursor must display one specific line. What line should we use? When the Cursor
type is set to linear, then the step of cursor movement is the number of lines in one pixel. When the maxs is set,
then the cursor is always move to the maximum line, which is contained in one pixel.
Record analysis speed
suppose the record length is 300 sec, it could be e.g. run up record. You want to measure the 1x amp+phase
(ampl+phase+speed) during the record. If you want to watch the continuous results, then select the real time
mode and the processing of record will take 300 sec (the analyzing time is the same time as the recording time
was). If you want to save results to the memory and not to watch them on the screen, then select fast mode.
The analyzing time will be much faster then 300 sec.
Record Analysis Start
selected for analysis.
It would be better to use example for explanation. E.g. we use record which length is 60 sec. We define time
signal measurement which length is 8 sec. It means when we push Start button, the reading takes 8 sec and
position of cursor moves of 8 sec in record.

IMPORTANT : when you moved the cursor manually, the the next reading will always start from that position.
