Single Channel Potentiostats
-
Potentiostats control a voltage and measure a resulting current. The Control Amplifier outputs power to the counter electrode (also called auxiliary electrode). A feedback loop is established to control the cell potential between the reference and working electrode. This voltage is measured by the input electrometer, that has a high impedance. This current is then measured between the working and counter electrodes while this potential is maintained at the working electrode and reference electrode.

Injection Transformer
J2101A
-
The injection transformer is presently the prevalent method for connecting the network analyzer to the circuit being tested, and is primarily used for control loop stability measurements. The goal of the transformer is to inject a signal into the control loop being measured, without impacting the performance of the loop. In order to accomplish this to a reasonable degree, The transformer is isolated and therefore is capable of floating on a high voltage, such as a Power Factor Corrector (PFC), which is often close to 400VDC. Measuring voltages that exceed the voltage rating of the FRA inputs require attenuation probes.
