  • Page 59: Timebase And Sampling Rate

    Measurement Configuration 3.3.2 Timebase and Sampling Rate The timebase setting establishes the rate of input signal waveform acquisition, specified as time-per- division on the horizontal axis (time/div). The sampling setting specifies the interval from one sample to the next. (The sampling rate is shown in brackets under the timebase for the Memory function (see illustration at right).
  • Page 60 Measurement Configuration To select the timebase Refer to the table below when setting the timebase. For example, to measure a 100 kHz waveform, the maximum display frequency setting range according to the table is 200 kHz - 800 kHz. If the maximum display frequency is set to 400 kHz, setting the time axis range to 10 μs/div is recommended.
  • Page 61 Measurement Configuration The sampling rate is automatically set to 1/100 of the selected timebase. If MR8990 Digital Voltmeter Unit is installed, that channel's sampling rate is automatically set to 1/50 of the selected timebase. Example: When 8966 is installed as unit 1 (CH1 and CH2) and MR8990 as unit 2 (CH3 and CH4), and the timebase is set to 1 s/div Sampling rate of unit 1 (8966): 10 ms Sampling rate of unit 2 (MR8990): 20 ms...

  • Page 418: Appx. 4 Fft Definitions

    FFT Definitions Appx. 4 FFT Definitions ■ What Is FFT? FFT is the abbreviation for Fast Fourier Transform, an efficient method to calculate the DFT (Discrete Fourier Transform) from a time-domain waveform. The reverse process of transforming frequency data obtained by the FFT back into its original time-domain waveform is called the IFFT (Inverse FFT). The FFT functions perform various types of analysis using FFT and IFFT.
  • Page 419 FFT Definitions Representing the above relationship on a complex flat surface produces the following figure.

  • Page 420 FFT Definitions ■ Number of Analysis Points The FFT functions of this instrument can perform frequency analysis of time-domain waveforms consisting of 1000, 2000, 5000, or 10,000 points. However, when the following conditions are satisfied, previously analyzed data can be reanalyzed with a different number of analysis points. A.
  • Page 421 FFT Definitions ■ Aliasing When the frequency of a signal to be measured is higher than the sampling rate, the observed frequency is lower than that of the actual signal, with certain frequency limitations. This phenomena occurs when sampling occurs at a lower frequency than that defined by the Nyquist-Shannon sampling theorem, and is called aliasing.
  • Page 422 FFT Definitions ■ Anti-Aliasing Filters When the maximum frequency component of the input signal is higher than one-half of the sampling frequency, aliasing distortion occurs. To eliminate aliasing distortion, a low-pass filter can be used that cuts frequencies higher than one-half of the sampling frequency. Low-pass filters used this way are called anti-aliasing filters.
  • Page 423 FFT Definitions Imaging When the instrument is set to a measurement frequency range that requires a higher sampling rate than the maximum capability of the module, intermediate data points are interpolated between successive data samples. In this case, the time-domain waveform exhibits a stair-step shape. When FFT analysis is performed in this situation, non-existent high frequency spectral components appear.
  • Page 424 FFT Definitions ■ Averaging With the FFT function, averaging is performed according to the following analytical expressions. Averaging in the time domain produces meaningless data if performed with inconsistent trigger criteria. (1) Simple Averaging (Time and Frequency Domains) ( ���� − 1 ) ���� + ����...

  • Page 426 FFT Definitions The following figure presents an example of spectral analysis by applying a window function to a time- domain waveform.

  • Page 428 FFT Definitions The following example shows input sine waves of 1050 and 1150 Hz analyzed with different window functions.
