CF-5200 Spectrum (Discontinued product)
FAQ
- I want to output only the overall value.
- I want to measure natural vibration, but what method?
- Can only the frequencies within a specified range be displayed on the screen?
- Even when using auto-scaling in spectrum view, the data does not appear.
- What is a phase spectrum?
- The operating procedure for the Max Overall function is as follows:
- Methods for evaluating the relationship between vibration and noise
- What does the triangle mark on the right edge of the screen represent?
- Real-time analysis is 32kHz even with dual-screen display.
- If we disable the display in the real-time analysis range using high-speed averaging mode, will it not exceed 32kHz?
- What is the formula for calculating the COP (Coefficient of Performance) of noise? (Example) 114.375Hz Spectrum = 35.96dB COH = 65% COP = 34.09dB
- The overall value obtained from a standard FFT analysis differs by about 4 dB from the overall value obtained from a 1/3 octave analysis.
- Amplitude flatness and full-scale accuracy refer to the values obtained when converting an accuracy of ±0.1dB to linear voltage when a sine wave with a single amplitude of 1V is input.
- The power spectrum average has settings for the number of cycles and time, but what is the relationship between them?
- We are measuring the spectrum of shock vibrations, but we are unable to perform the analysis as we would like.
- The relationship between the dB/V values when the Y-axis is switched between Log/LIN is as follows:
- (1) Can harmonic analysis of current and voltage be performed simultaneously? (2) What is the method for measuring the phase lag of harmonics?
- I'm performing an FFT on the vibration waveform in the 500Hz range, but it's not showing up on the display. When I turn off the digital filter, it displays around 250Hz, but I don't know why.
- What is the cutoff frequency of the AC coupling?
- (1) What is the display cycle for the three-dimensional display? (2) What is the method of measurement?
- The FFT average is being taken, but what is the duration of one measurement?
- An 80Hz signal is input, and FFT is performed on a rectangle graph. The curve is steep in the 2kHz range, but widens at 5kHz.
