Tekbox TBJT02 wideband injection transformer
Details
The Tekbox TBJT02 is a wideband injection transformer for making bode plots to measure the stability of power supplies and converters. The transformer injects a testsignal in the control loop to measure the effect on the system. It provides galvanic isolation between the signal source and the control loop. The injection transformer itself is internally terminated with a 5 Ω resistor and protected with a 100 mA fuse. This transformer has a usable frequency range of 1 Hz - 7 MHz. The transformer input is connected with a 50 Ω BNC female connector and the output is connected with 4 mm safety banana plugs.
