Math scale and offset

160
Any math function may be manually scaled by pressing the
Settings softkey, and then adjusting the Scale or Offset value.
Math Scale and Offset are Set Automatically
Any time the currently displayed math function definition is changed, the function
is automatically scaled for optimum vertical scale and offset. If you manually set
scale and offset for a function, select a new function, then select the original
function, the original function will be automatically rescaled.
1 Press the Settings softkey in the Math menu to set your own
scale factors (units/division) or offset (units) for the selected
math function.
Units for each input channel can be set to Volts or Amps
using the channel Probe Units softkey. Scale and offset units
are:
Math function
FFT
1*2
1-2
d/dt
dt
* When the FFT source is channel 1, 2, 3 or 4, FFT units will be displayed in
dBV when channel units is set to Volts and channel impedance is set to
1 M . FFT units will be displayed in dBm when channel units is set to Volts
and channel impedance is set to 50 . FFT units will be displayed as dB for
all other FFT sources or when a source channel's units has been set to
Amps.
A scale unit of U (undefined) will be displayed for math
function 1-2 and for d/dt, and
selected source if channel 1 and channel 2 are set to
dissimilar units in the channel Probe Units softkey.
2 Press the Scale or Offset softkey, then turn the Entry knob to
rescale or change the offset value for your math function.
