 +The [[https://​store.digilentinc.com/​impedance-analyzer-for-analog-discovery/​|Impedance Analyzer for Analog Discovery]] can be used to ease use of the Impedance Analyzer instrument. It automatically selects the best configuration for several reference resistors and relays to measure an unknown impedance.

 +The Impedance Analyzer attaches to the MTE cable connector slot on the Analog Discovery 2. A load, whether a single component, or a circuit to test, should be connected to connector J2, and the component or jumpers should be locked in place with the orange clips.
