CF-5200 Spectrum (discontinued product)
FAQ
- I want to output only the overall value.
- I want to measure the natural vibration, but what is the method?
- Is it possible to display only the frequencies of the specified interval on the screen?
- Even when using auto-scale in the spectrum display, the data does not appear.
- What is a phase spectrum?
- The operating procedure for the max overall function is
- How to evaluate the relationship between vibration and noise?
- What does the triangle mark at the right edge of the screen indicate?
- Real-time analysis can operate at 32kHz even with a two-screen display.
- If display is prohibited in high-speed average mode, will it not exceed 32kHz?
- What is the formula for calculating the COP of noise data? (Example) 114.375Hz spectrum = 35.96dB C0H = 65% COP = 34.09dB
- The overall value obtained from the standard FFT analysis differs by about 4 dB from the overall value obtained from the 1/3 octave analysis.
- Amplitude flatness and full-scale accuracy. When a sine wave with a peak amplitude of 1V is input, the value when converting the accuracy of ±0.1dB into linear voltage is.
- There is an average of the power spectrum with settings for frequency and time, but what is the relationship between them?
- I am measuring the spectrum of shock vibrations, but I cannot perform the analysis as I would like.
- The relationship between the values in dB/V when switching the Y-axis between Log and LIN.
- (1) Is it possible to perform simultaneous analysis of current and voltage harmonics? (2) What methods are there to measure the phase delay of harmonics?
- The vibration waveform is being FFT analyzed in the 500Hz range, but it does not appear on the display. When the digital filter is turned off, it shows around 250Hz, but for some reason.
- What is the cutoff frequency of AC coupling?
- (1) The display cycle of three-dimensional representation (2) The method of actual measurement
- What is the duration of a single measurement while taking the average of the FFT?
- An 80Hz signal is input, and the FFT is performed on a rectangle. In the 2kHz range, it is steep, but at 5kHz, it becomes more spread out.
