Parameters
Y1: Voltage level of the upper cursor.
Y2: Voltage level of the lower cursor.
Y1Y2 The difference between the upper and lower
cursor.
V/A ( OD-411/415 ) The voltage / current difference (Y1-Y2).
Cursors adjustment
1. To move the upper cursor, pres Y1 , and then use the VARIABLE [3]
knob.
2. To move the low cursor press Y2 , and the use the VARIABLE [3]
knob.
3. To move both cursors, press Y1 Y2 , and then use the VARIABLE [3]
knob.
4. Press Cursor to remove the onscreen cursors.
5.3 Math operations
The Math operations can add, subtract, multiply or perform FFT/FFT
RMS on the input waveforms. The resulted waveform can be measured using
the cursors, and saved or recalled just like normal input signals.
Addition (+) Adds amplitude of CH1 & CH2 signals.
Subtraction (—) Extracts the amplitude difference between CH1
& CH2.
Multiplication (x) Multiplies CH1 and CH2 (OD-411, OD-415
only).
FFT Performs FFT calculation on a signal. Four
types of FFT windows are available: Hanning,
Flattop, Rectangular, and Blackman.
