The impedance Analyzer description said “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 we used the IA and "constant voltage" mode, the alarms turn on more than we have expected
Here, we show the impedance behavior of the same DUT (RC circuit), using the constant voltage mode (10 mV), with or without the impedance Analyzer adapter, alternatively.
When we used the W1-C1-DUT-C2-R2-GND configuration (without the adapter) with external 4,7kOhm reference resistor, the resistor alarm was turn off for all the frequency range. While, when we used the adapter (with six internal reference resistors), the “resistor too High” alarm turned on in almost all the frequency range.
why the constant voltage mode turn the resistor alarm on?
How can we solve the resistor alarm using adapter and constant voltage mode?
