RENT PICOTEST J2100A Injection Transformer (Call for Availability)
The PICOTEST J2100A Injection Transformer is the optimal solution for establishing reliable connections between network analyzers and circuits under test, particularly in control loop stability measurements. Engineered to inject signals without altering the performance of the control loop, this transformer emphasizes measurement integrity and precision.
This highly versatile injection transformer is isolated, allowing it to float on high voltages, such as those found in Power Factor Corrector (PFC) applications, which can reach up to 400VDC. To accommodate for measuring voltages that exceed the Bode-100 input ratings, attenuation probes are necessary for safe and accurate assessments.
One of the defining features of the J2100A is its impressive usable bandwidth, which typically surpasses the conventional 3dB frequency limits. By keeping the transformer outside of the measurement scheme, it challenges the misconception of it being a non-critical component. Moreover, the bandwidth is optimized by the terminating impedance; utilizing the 50 Ohm oscillator source impedance provided by most network analyzers, an optimal termination resistor of 5 Ohms is employed to minimize the injection signal's impact on the measured loop.
This thoughtful design helps prevent common errors associated with large signal measurements, making it easier to achieve small signal accuracy. The low termination resistor value can often remain integrated into the circuit during routine operations, streamlining the connection process to the network analyzer without significantly affecting the test circuit's output voltage.
Key Features of the PICOTEST J2100A Injection Transformer Include:
- 1Hz capability to support PFC regulators
- 5MHz bandwidth suitable for most power supplies and regulators
- Extensive 23 Octave range for broad application versatility
- Low distortion for enhanced precision in measurements
