I find that the output voltage of the function generator as measured by a digital voltmeter or an oscilloscope is substantially higher than that indicted in the PC display.
For example, with a pure 165Hz sinewave output and display indicated voltage = 2.86 volt rms and 8.09 volts p-p, and offset = 0.00 volts, the actual measured voltage as determined by my scope and digital voltmeter is 3.33 volts rms.
