Bergoz Instrumentation Radio-Frequency Current Transformer CT-RF provides an accurate measurement of continuous wave
The CT-RF transformer output signal is an accurate voltage waveform representation of the measured current, which can be analyzed on an oscilloscope, RF power meter, spectrum analyzer or custom interface circuitry.
Applications:
- RF current and phase measurement between source and load (e.g. plasma chamber)
- Harmonics, distorsion, impedance match
All transformers can be shipped with a certificate of calibration and factory test data, ensuring optimum performance levels are realized. Vector network analyser files amplitude response vs. frequency and phase vs. frequency can be supplied.
