I am looking to measure an LDO gain/phase with the J2110A solid state injector. But, I am confused about the connections to do so on the module.
Here is a very simple block diagram of the LDO. Normally, I have an injection resistor between VOUT and Rtop. Then, I measure across this resistor to get my gain phase. However, I see in the line injector manual that an injection resistor isn’t needed for the J2110A just that the “that the impedance on the Vout side must be different from the Rtop side”
Am I supposed to connect “OUT” on the J2110A to VOUT and connect “IN” to the non-inverting input of the error amplifier (op-amp on the left) like traditional bode analysis?
