CF-5200 Transfer Function (Discontinued Product)
FAQ
- I want to display the transfer function, but I want to perform the test using an impulse hammer.
- In the mechanical impedance measurement (force/velocity), channel A is input Accelerometer and channel B is input from a force (impulse hammer). The transfer function is obtained, but the coherence function is not.
- I want to see the phase difference between the two signals.
- Regarding the meaning of the transfer functions a/F and F/a between impulse excitation F and acceleration a.
- The inter-channel phase correction function does not work even when the PHASE ADJ function is turned ON (it remains at 0.26 degrees). A 50kHz square wave 1V input is being used.
- This is my first time using it. I want to test the impulse hammer, but how do I operate it?
- During the hammering test, a double hammering alarm appeared in the acceleration waveform.
- Phase correction is not possible below 10kHz, but is it possible to correct at 50Hz?
- The meaning of phase unwrapping is
- Accelerometer are attached between two points on a structure, and the transfer function between the two points is measured by striking a specific point. There are several measurement points. Will there be a difference between measuring simultaneously with one strike and measuring one point at a time?
- Is it possible to perform a partial overall processing of the power spectrum using a transfer function?
- I want to measure the phase lag of voltage and current harmonics.
- The criteria for determining the natural frequency from the data obtained by impact testing to determine FRF, PHASE, and COH are as follows:
- How to interpret FRF data before and after structural improvements
- What does a -5% damping factor mean in the half-width method?
- I would like to find books and materials on impulse hammer measurement.
