Syntax
MATH[1]:HORizontal:POSition <NR3>
MATH[1]:HORizontal:POSition?
Arguments
<NR3> is a floating point number that specifies the % of the math waveform that
precedes center screen. It can vary from 0.0 to 100.0.
Examples
MATH:HORIZONTAL:POSITION 10 sets the horizontal position to 10% pretrigger
MATH[1]:HORizontal:SCAle
This command specifies the math horizontal display scale for FFT or for dual
math waveforms that have source waveforms that are reference waveforms. The
horizontal scale of a dual math waveform with a channel source waveform is set
through the command.
