Transistor DC Bias Characteristics Test

Description

Use SFG-2000 series as the signal source for a transistor.
Compare the transistor input/output waveform using the

oscilloscope. Adjust the DC voltage source to find out
the maximum output without distorting the waveform.

Amplifier Over-Load Characteristic Test

Description

Use the triangle wave output from SFG-2000 series to
check the amplifier output distortion caused by overload.

The common sine wave is not the ideal source in this
case. Observe the linearity of the triangle waveform

using an oscilloscope.

Amplifier Transient Characteristics Test

Description

Use the square wave output from SFG-2000 series to
check the transient frequency response of an amplifier.

The common sine wave is not the ideal source in this
case. Observe the waveform using an oscilloscope.
