 Test procedure
<1> Set the waveform of the signal generator to sine wave, and set the frequencies shown in "
Table
6-1 Judgment of HSA42011 Performance
".
<2> Set the output on/off switch of this product to ON.
<3> Increase the output voltage of the signal generator gradually from 0 V.
<4> Observe the waveform on the oscilloscope. Record the output voltage value when the waveform
begins to be distorted or the overload LED (OVLD) begins to be glow.
