TEKBOX TBJT01 Injection Transformer Installation Guide
Introduction
The TBJT01 is a wideband injection transformer for control loop stability measurements. It provides galvanic isolation between the swept signal source and the control loop. The injection transformer is internally terminated with a 5 Ohm resistor and protected with a 100 mA fuse. The usable frequency range is 10 Hz to 45 MHz.

Application
The control loop is commonly broken at the point between the amplifier output
and the input of the feedback network:
The isolation transformer is inserted into the control loop and connected to
the BodeAnalyzer:
