How to shorten servo analysis time?
I will outline the overview of the servo functions below. The reduction of measurement time depends on the settings, so please make the necessary operational adjustments.
(1) The sine sweep method involves maintaining a constant sine wave until a certain number of sampling points (for example, 2048 points) are obtained, then calculating the FFT for those 2048 points at that frequency, and repeating the process for the next frequency. The time taken to sample 2048 points increases with lower frequencies, resulting in longer measurement times. The more accurately measurements are taken, the longer the measurement time tends to be. Measurement time can be shortened when the number of sample points is smaller, the frequency range is larger, the number of measurement decades is smaller, the points per decade is fewer, and when using pseudo-random instead of sine sweep.
(2) Another method is the sequence control function. You can set a program where the range requiring precision is configured as a sine sweep, while others can be set to pseudo-random or swept sine.
