Multiply

When you select 1 * 2, channel 1 and channel 2 voltage values are multiplied
point by point, and the result is displayed. 1 * 2 is useful for seeing power
relationships when one of the channels is proportional to the current.
• Press the
if you want to change the scaling or offset for the multiply function.
Scale allows you to set your own vertical scale factors for multiply expressed
as V
(Watts/division or Volt-Amps/division). Units are set in the channel Probe menu.
Press the Scale softkey, then turn the Entry knob to rescale 1 * 2.
Offset allows you to set your own offset for the multiply math function. The
offset value is in V
represented by the center graticule of the display. Press the Offset softkey, then
turn the Entry knob to change the offset for 1 * 2.
