Auto Transformers
-
Osborne often recommends Auto Transformers in situations where reducing physical size of the transformer is advantageous. Auto transformers offer size advantages when compared to equivalent isolation transformers. Auto transformers provide lower levels of regulation than the equivalent isolation transformer. Osborne helps our clients accommodate for the loss of regulation while achieving the physical size (and cost) advantages of auto transformers.

Low Input Bias Current Op Amps (≤100 pA)
-
Low input bias current op amps are required whenever the difference of currents or voltage is small and needs to be measured accurately. These op amps are used so that the signal is not loaded down by the input of the op amps. Low input bias current op amps are critical for interfacing sensors in applications from photodiodes, pH meters, or other electrometer related functions to downstream electronics. Analog Devices has many precision op amps that fit the definition and range of these applications.

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.
