√ (square root) calculates the square root of the selected source.
In Zoom mode, the √ (square root) function does not display in
the zoomed portion of the display.
1Press 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 V1/2/div
(Volts-square-root/division), A1/2/div
(Amps-square-root/division), or W1/2/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 V1/2 (Volts-square-root),
A1/2 (Amps-square-root), or W1/2 (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.
