RENT PICOTEST J2101A Injection Transformer (Call for Availability)
The PICOTEST J2101A Injection Transformer is an essential tool for professionals who demand the highest precision in control loop stability measurements. Designed to seamlessly connect a network analyzer to the circuit under test, this injection transformer delivers optimal performance without disrupting the operational integrity of the loop.
Its isolated architecture enables the J2101A to float at high voltages, particularly beneficial for applications involving Power Factor Correctors (PFC) that may reach up to 400VDC. Notably, when measuring voltages exceeding the Bode-100 inputs' voltage ratings, attenuation probes are recommended to ensure signal integrity.
The usable bandwidth of the injection transformer extends well beyond standard 3dB frequency limits, as it operates outside of the measurement domain. This adaptability is critical for accurate readings, as it minimizes the misconception that the transformer is a non-essential element in the measurement process. The bandwidth is intricately linked to the terminating impedance; thus, it is optimized at a value of 5 Ohms when used with network analyzers like the Bode-100, which typically provide a 50 Ohm oscillator source impedance.
This low termination value not only effectively attenuates the injection signal—improving measurement accuracy by mitigating the common error of overly large signal inputs—but it also allows for the transformer to remain in the circuit continuously. This feature simplifies connectivity to network analyzers while preserving the output voltage of the tested circuit.
