Injection transformer range

N4L accessories

When testing the transfer function of a control loop, a 'disturbance signal' from which frequency response analysis can be made is 'injected' into the loop.

In order to ensure that the test system does not change the transfer function results, it is important that the signal generator providing the disturbance signal is isolated from the circuit being tested.

This isolation can be achieved using a transformer that meets the frequency range and voltage isolation requirements of a specific test environment, so N4L offer a number of different injection transformer models.
