LCR meter with Front_End instrument

Post by redpitaya » Mon Jun 02, 2014 2:19 pm

Here we continue with the LCR meter with Front_End instrument.

The project was proposed by a group of students from University of Ljubljana.

Original proposal is located HERE. Below is the copy/paste of the proposal:

The expected specifications of our instrument are the following:
  • 100Hz to 500kHz continous frequency range
    0.5% basic measurement accuracy
    the device will be able to measure 10 impedance parameters
    4terminal Kelvin connections
    automatic parametric frequency sweep

    default or custom test signals:
    default - AC voltage, programmable from 20mV to 0.5V
    custom - transient voltage signal with max amplitude: +- 0.5V, can be imported or included as a transfer function

    DC bias voltage 0.5V
    test frequency accuracy +- 0.02Hz
    manual calibration for short/open connections
    graphical interface includes results shown in plots and tables
    can calculate the average of up to 100 measurements
    manual/automatic and smart data acquisition functions
    export your data in multiple formats
parameter/expected measurement range/expected accuracy
Ls, Lp // 10.000 nH to 10.000 H // +/- 0.2%
Cs, Cp // 1.000 pF to 2.000 F // +/- 0.2%
DF // 0.0001 to 100.00 // +/- 0.1
Q // 0.00000 to 10000.00 // +/- 0.01
Y, Gp, Bp // 10.00 nS to 1000.00 S // +/-0.01
|Z|, Rs, Rp, Xs, ESR // 0.01 mΩ to 10.000 MΩ // +/- 0.2%
phase angle // -160.00 to +160.00 degrees // +/- 0.5%
DUT AC voltage // 20 mV to 1.0 V // +/- 0.2%
DUT AC current // 10 μA to 100 mA // +/- 0.2%
DUT DC voltage // 20 mV to 1.0 V // +/- 0.2%
DUT DC current // 10 μA to 100 mA // +/- 0.2%
