DPO6000, MPO6000 Series Digital Fluorescent Oscilloscope Product Manual V1.3
64
[Offset]: Set the vertical offset of the operation waveform relative to the time axis;
[Scale]: Set the unit volt value in the vertical direction.
The setting of the operation waveform in the horizontal direction is the same as that of
the data source waveform.
[Setting] is not available at this time.
Subtraction
Subtract the waveform values of data source 1 and data point by point and display the
result.
The operation steps are the same as those of [Addition].
Multiplication
Multiply the waveforms of data source 1 and data source 2 point by point and display
the result.
The operation steps are the same as those of [Addition].
The units of the calculation waveform "offset" and "scale" are user-defined (represented
by U).
Division
Divide the waveform of data source 1 and data source point by point and display the
result. It can be used to analyze the multiple relationships between the waveforms of
two channels.
The operation steps are the same as those of [Addition].
Note: When the voltage value of data source 2 is zero, the operation result is treated as
invalid.
The units of the calculation waveform "offset" and "scale" are user-defined (represented
by U).
FFT
FFT uses the analog input channel waveform to calculate a fast Fourier transform. The
FFT operation can be used to convert a time domain (YT) signal into its frequency
components (spectrum), showing the relationship between dB V and frequency. The
horizontal axis reads from time to frequency (Hz) and the vertical reads from V to dB.
FFT operations can be used for the following tasks:
◆ Measure harmonic content and distortion in the system
