I'm a new Discovery 2 user that's trying to measure impedance. I running Waveforms 3.10.9 Windows 10 64 bit. I made a simple circuit with a 2k R as DUT W1 C1   2k R   C2   1k R   GND and ran a 1k  compensation shorting W1, C1 and C2 to one side of the 1k R and GND to the other side and open with all unconnected. Doing a low frequency sweep from 1 kHz to 10 kHz I see results like Rs: 29.9 k   Xs: -46.8 k   theta: -57 at 2 kHz. Any ideas why this is so far off?
