P11.6. Evaluation of the Gain with Sine-Wave and Square-Wave Signals
Procedure
SignalAmp.vi sends out a sine- or square-wave input signal with a frequency as selected from the Front Panel. Use a frequency of 1 or 2 Hz. It must be low as the frequency response of the amplifier is very low with the high gain of this configuration.
Install resistor values in the Front Panel of SignalAmp.vi.Run the VI and compare the gain for sine- and square-wave signals. Compare for two different frequencies. Adjust Vs for a maximum output signal of about 1 V. Save the Front Panel.
