Etudes de cas

Mesure d'impulsions dans le domaine fréquentiel

par L. DUVILLARET/G. GABORIT

(AN24-FDPM-09)

Measuring gated-CW pulses in the frequency domain is not straightforward especially when considering weak signals. Using a spectrum analyzer as demodulator, the envelope of the pulses can be carried out. However, the recommended setup requires a signal generator with a trigger output which is usually not a native feature. To overcome that issue, a low frequency generator is added. With a robust model of the spectrum analyzer behavior, accurate measurements of peak signal amplitude only 1 dB above noise floor is achievable.

Caractérisation de la cavité RF

par L. DUVILLARET

(AN24-RFC-07)

RF / microwave cavities are of key interest for their use as oscillators, filters and also to expose devices to High Power Electro-Magnetics. One of the key parameter of a RF Cavity (RFC) is its quality factor Q linked to E-field strength that could be reached inside the RFC. However, as soon as a device is introduced inside, both resonant frequency and Q factor are modified. We show here how an optical E-field probe can be used to characterize a RFC while inducing almost no interference.

Mesure d'impulsions dans le domaine temporel

par L. DUVILLARET

(AN24-TDPM-03)

Measurement of single or repetitive pulses in the time domain would be straightforward using an infinite bandwidth measurement system as the spectral content of pulses spread usually over an ultra wide band. However, in the real life, both sensor and digitizer present finite bandwidths and the choice of both sensor and digitizer is not straightforward. We illustrate through a few examples how to get the best trade-off when making E-field measurements of pulses.

Mesure en temps équivalent avec des signaux bruités

par L. DUVILLARET

(AN21-ETD-01)

Measurement of repetitive signals using a Digital Sampling Oscilloscope (DSO) is linked to Equivalent Time-Domain (ETD) measurements. Making measurements of noisy signals in ETD leads to a great enhancement of the Signal-to-Noise Ratio (SNR) by making the average of a large number of samples...

Mesure domaine temporel en IRM

par G. GABORIT

(AN22-MRI-01)

The measurement of ElectroMagnetic (EM) pulses generated by a MRI apparatus inside phantoms is of key importance for MRI safety. This latter one is related either to the local temperature increase of the phantom or to the RMS value of the local Electric (E) field, this latter physical quantity being much more easy to assess thanks to the use of appropriate E-field sensors...

Problématique des interférences électromagnétiques

pour le test d'antennes

When dealing with RF experiments, ElectroMagnetic Interference (EMI) constitutes a classical issue that limits the measurement accuracy when it doesn’t prevent making measurement. Identifying the source of EMI remains a challenge and solving EMI issue is generally time-consuming and costly...

Etalonnage de sondes de champ électrique

par L. DUVILLARET

(AN21-EFPC-04)

Electric (E) field probes need to be calibrated in order to get absolute E-field strength values. Contrary to other sensors (temperature, pressure...), the sensitivity of E-field probes depend on the medium in which the probe is placed. An E-field probe calibrated in air gives a wrong result when used inside water or inside any other liquid...

Utilisation d'eoCal™ HF6

(AN21-eoCal-01)

Electric (E) field probes need to be calibrated in order to get absolute E-field strength values. Their calibration in air is straightforward for frequencies up to 6 GHz thanks to adiabatic TEM cell...
