Square Root
√ (square root) calculates the square root of the selected
source.
In Delayed sweep horizontal mode, the √ (square root)
function does not display in the delayed portion of the
display.
1 Press the Math key, press the √ (square root) softkey, then
press the Source, Scale, or Offset sofkeys if you want to
change the source, scaling, or offset for the square root
function.
• Source — selects the source for √ (square root). The
source can be any analog channel, or math functions
1 + 2, 1 – 2, and 1 * 2.
• Scale — lets you set your own vertical scale factors for √
(square root) expressed as V
1/2
/div
(Volts-square-root/division), A
1/2
/div
(Amps-square-root/division), or W
1/2
/div
(Watts-square-root/division or
Volt-Amps-square-root/division). Units are set in the
channel Probe menu. Press the Scale softkey, then turn
the Entry knob to rescale √ (square root).
• Offset — lets you set your own offset for the multiply
math function. The offset value is in V
1/2
(Volts-square-root), A
1/2
(Amps-square-root), or W
1/2
(Watts-square-root) and is represented by the center
horizontal grid line of the display. Press the Offset
softkey, then turn the Entry knob to change the offset
for √ (square root).
A scale unit of U (undefined) will be displayed for scale
and offset when 1-2 or 1+2 is the selected source if
channel 1 and channel 2 are set to dissimilar units in the
channel Probe Units softkey.
