One of the 12 instruments of the Analog Discovery is the Impedance Analyzer instrument, which allows the user to analyze inductive and capacitive elements of a circuit under test. The Impedance Analyzer for Analog Discovery provides automatically adjusting reference resistors and relays, so that reference circuits don't have to be manually built for each test. 

When plugged into the Analog Discovery, and connected to WaveForms the Analog Discovery will automatically select the most appropriate configuration for the attached unknown impedance. The adapter is loaded with a 2x15 female connector which can be plugged in directly to the Analog Discovery. Components or leads can be attached via the spring terminal block on the Impedance Analyzer. 

Note: Use of this adapter requires WaveForms version 3.8.2 or later.

    Broken out of the box

    The selectable series resistor feature did not work. Changing the Resistor in waveforms did not result in clicking of the relays or effective changing of the resistance. The series resistance was always 100kohms. At the 100kohm setting, it preformed well with similar sized impedances, but could not measure the low impedance I wanted to.

    IMPEDANCE ANALYZER FOR ANALOG DISCOVERY

    Posted by Lars Lindner on 29th Apr 2021

    I am using this adapter to conduct analysis of mixed load characteristics circuits. I am developing a simple GUI in Python, to do frequency scans of an 4MHz crystal for research purpose. Thank you Digilent team.

    Impedance analyzer

    used the device to measure parameters of low frequency solenoid, one that could expect inductance formulas to work. The device was right on for the inductance, but measures series resistance and self-resonant frequency, which is difficult to calculate accurately. Very pleased with the device. Agree the DUT connector is problematic though. I simply stripped some solid wire & attached alligator clips to the remote device. Performed open & short tests first, though. In spite of the DUT connector I think it still worth a five.

    Works great

    Worked better than I thought it would, and for the price, you just can't beat it.

    Handy add-on

    Posted by Digilent Customer on 8th Aug 2018

    This add-on board makes doing impedance testing so much easier, smoother and faster. I've used it for testing coils, caps filters etc, and found it to be pretty trustworthy. A great quick learning tool.

    More accurate than I expected

    Posted by gasstationwithoutpumps on 7th Jul 2018

    I reviewed this at https://gasstationwithoutpumps.wordpress.com/2018/07/01/analog-discovery-impedance-analyzer/ The board works fairly well, if you do the open-circuit and short-circuit compensation. I think that the reference resistors are mostly 0.2% components (accuracy is not specified on the data sheet). I was a little surprised by the use of latching relays with up to 100mΩ contact resistance—lower resistance is possible with FET switches. The connector used for DUT requires long leads (a shorting plug made with double-ended male headers was not long enough to reach the contacts), which may cause problems for measuring some components, requiring adding extra wiring.
