TekBox TBJT Wideband Injection Transformers
TekBox TBJT Wideband Injection Transformers
TekBox Models TBJT01, TBJT02, TBJT03 with Frequency Ranges up to 45, 7, 50 MHz
The TekBox TBJT01, TBJT02, and TBJT03 are wideband injection transformers for control loop stability measurements. They provide galvanic isolation between the swept signal source and the control loop. The injection transformers are internally terminated with a 5 Ω resistor and protected with a 100 mA fuse. The usable frequency range is 10 Hz to 45 MHz (TBJT01), 1 Hz to 7 MHz (TBJT02), or 150 kHz to 50 MHz (TBJT03).
- Usable frequency range 10 Hz...45 MHz (TBJT01), 1 Hz...7 MHz (TBJT02), or 150 kHz...50 MHz (TBJT03).
- 3-dB frequency range 15 Hz...9 MHz typ. (TBJT01), 2 Hz...3 MHz typ. (TBJT02), or 50 kHz...50 MHz typ. (TBJT03).
- Characterized frequency range 1 Hz...100 MHz.
