Hi everyone! I am measuring a voltage divider with R₁ = 500 kΩ and R₂ = 1 MΩ, using a sinusoidal input signal Vₑ with an RMS voltage of 3V. According to calculations, the expected RMS voltage at the midpoint of the divider should be 2V, but when measuring with an oscilloscope, I only get 1 mV...
Dear Members,
I hope you are all doing well.
I am a PhD student and completely new to circuit design. I need a compact-sized circuit and prefer not to use an impedance analyzer due to its bulkiness. I am looking to build a circuit capable of automatically measuring the impedance of a sensor in...

I'm needing to make some measures of low frequency impedance (1-1kHz range) of some liquid solutions and plaster samples.
1) What would be a good tool for measuring impedance for around $500? I see mostly very high price ranges for impedance analyzers ($2k or more).
2) Also, when shopping for...
