Group Vertical
Syntax
REF<x>:POSition <NR3>
REF<x>:POSition?
Arguments
NR3
is the desired position, in divisions from the center graticule. The range is
±1000 divisions.
Examples
REF2:POSITION 1.3E+000
positions the Reference 2 waveform 1.3 divisions
above the center of the display.
REF1:POSITION?
might return
REF1:POSITION 2.000000000000
, indicating
that the Reference 1 waveform is positioned 2 divisions above the center of the
display.
REF<x>:SCAle
This command allows you to set or query the vertical scale of the speci fi ed
reference waveform. The waveform is speci fi ed by x, which can be 1 through
8. This is the equivalent to specifying a reference waveform in the Waveform
section of the Vertical Setup dialog box and then entering a value for Scale in
the Setup section.
Increasing the Scale causes the waveform to be displayed smaller. Decreasing the
scale causes the waveform to be displayed larger. For reference waveforms, this
setting controls the display only, graphically scaling these waveforms and having
no effect on the acquisition hardware.
Group Vertical
Syntax
REF<x>:SCAle <NR3>
REF<x>:SCAle?
Arguments
NR3
is the vertical reference scale in units per division.
Examples
REF4:SCALE 1.0E-02
sets the Reference 4 waveform scale to 10 mV per
division.
REF1:SCALE?
might return
REF1:SCALE 0.100000000000
, indicating that
the current volts per division setting of the Reference 1 waveform is 100 mV
per division.
