PURPOSE:To offer the evaluation test equipment able to evaluate an automatic preset function by employing two sets of signal oscillators. CONSTITUTION:The above equipment is provided with a 1st signal oscillator 101 oscillating a signal of a 1st frequency, a 2nd signal oscillator 102 oscillating a signal of the 2nd frequency different from the frequency of the signal oscillated from the 1st signal oscillator 101, a high frequency amplifier 103 inputting the output of the 1st signal oscillator 101 and the output of a 2nd signal oscillator 102 and having a nonlinear amplifier characteristic, a signal attenuator 104 attenuating the output of the high frequency amplifier 103 to a prescribed level. |
