I dont understand...
* measure at the same point, but without 1kHz input signal, then you see how much the input has influence
* measure at the sane point but without input signal and without running pwm (but supplied with power, to see how much the pwm influences the signal)
* measure at the same point, but power supply VCC disconnected, but GND connected (no signal is generated at your application, so you only see the influence of mains connection, (maybe GND loops,...) and the errors caused by the measurement equippment)
