Configuring math waveforms
1. Press the [Math] key.
The math waveforms are activated, using the latest settings.
2. Press the [Math] key again.
The "Mathematics" menu and the "Equation Set Editor" are shown.
3. Configure the equations of the math waveforms in the "Equation Set Editor". You
can define up to 5 equations. The complete configuration is called equation set and
can be saved for later use.
a) Tap the row of the math waveform that you want to configure.
b) To activate the math waveform, set its "State".
c) Select the "Operation".
d) Select the "Source(s)", the operands of the mathematical equation: 1 or 2 ana-
log channels, constant values or math waveforms. Only math waveforms of
lower order are available, for example, M2 can be a source for M3, M4, and
M5. For M1, math waveform sources are not available.
e) Select the "Unit".
f) Optionally, add label to the math waveform. The label is shown at the right
edge of the grid.
4. Close the "Equation Set Editor".
5. To adjust vertical scale and position using vertical knobs:
a) Select a math waveform in the short menu.
b) Use the rotary knobs in the Vertical section of the front panel. See:
ter 5.3.1, "VERTICAL controls"
6. To enter exact values for vertical scale and position:
a) Open the "Mathematics" menu.
b) In the "Equation Set Editor", select a math waveform.
c) In the menu, enter "Vertical Scale" and "Position".
