RLC Impedance measurement

[dellectronics]

Hello all.

I'm looking for a scope and logic analyzer for low bandwidth and good Msps (Analog Discovery 2 seems to be fine for me). One of the main purposes is the impedance characterization of piezoelectric ceramics (capacitors) up to 20kHz.

Is it possible to make an easy script to make the frequency sweep and measurement of voltage and current (using a shunt resistor) to make that characterization with AD2?

Similar to the LCR app of Redpitaya.

 

Best Regards!

Hello,

I think you are looking for Network Analyzer.
The software features can be tested in demo mode too https://reference.digilentinc.com/waveforms3

Thanks!

Hello,

The forum post below from a year ago shows a screenshot of the unfinished impedance analyzer that's presently 'hidden' in the WaveForms software (at least in v2.7.5). Hopefully this useful tool will be made available for our use in the near future. It would make the already excellent software even better.

Thanks for your answer fpliuzzi.

 

Using the lastest version and with the DEMO mode, there is no Impedance Analyzer, but seems to be a really nice instrument and hopefully we could have it in near future.
