| Zusammenfassung: | The utility model discloses a signal generating device is pressed to dynamic aperture, include: the air feed module, the host computer, the first control valve, second control valve and insert the formula tee pipe coupling soon, but the first control valve generates hyperbolic curve type growth frequency modulation pressure signal according to the first atmospheric pressure source of air feed module production and a turn -on signal of host computer output, but the second control valve generates sinusoidal formula frequency modulation pressure signal according to the second atmospheric pressuresource of air feed module production and the 2nd turn -on signal of host computer output, but but insert the formula tee pipe coupling soon and superpose and obtain the dynamic aperture and press thesignal through increasing hyperbolic curve type frequency modulation pressure signal and sinusoidal formula frequency modulation pressure signal. Therefore, the utility model discloses a signal generating device is pressed to |
