- Designed specifically as a wideband injection transformer for control loop stability testing.
- Provides galvanic isolation between the signal source and the control loop.
- Internally terminated with a 5 Ω resistor to support proper signal injection.
- Protected with a fuse on the secondary (output) side for safety.
TBJT02
wideband injection transformer
The TBJT02 is a wideband injection transformer designed for control loop stability measurements. It provides galvanic isolation between the swept signal source and the control loop under test. The injection transformer is internally terminated and protected, offering reliable performance for loop analysis and Bode measurement setups.
