Disturbance Power Measurements in Real-Time

real-time measurementsMeasurement of disturbance power is carried out with an absorbing clamp in the frequency range of 30 MHz to 300 MHz. It is an alternative test method to radiate emission measurements. Therefore, the maximum emission has to be found and recorded, which is received by the absorbing clamp moved along the slideway. Usually a frequency search is performed in the first step. The following measurement of the maximum is performed with the Quasi-peak detector at single frequency points. Typically the test receiver was set to a frequency and the absorbing clamp was shifted until the maximum emission was found.

Compared to this time-consuming test procedure, the maximization at all frequency points over a bandwidth of 30 MHz to 300 MHz can be carried out now by the TDEMI X receiver instantaneously with a full gapless real-time bandwidth of 325 MHz from GAUSS INSTRUMENTS.

CISPR-Average detector, as well as Quasi-peak detector are running in parallel and are measureed simultaneously over the whole frequency range at once, and are displayed in real-time during the measurement. The measurement is performed by the receiver of the TDEMI X series in the real-time spectrogram mode, which is full CISPR-compliant, and with MaxHold traces activated. The absorbing clamp is continuously moved over the full length of the slideway and the measurement of disturbance power is completed in approximately ten seconds.

A Dash of Maxwell’s: A Maxwell’s Equations Primer – Part Two

Maxwell’s Equations are eloquently simple yet excruciatingly complex. Their first statement by James Clerk Maxwell in 1864 heralded the beginning of the age of radio and, one could argue, the age of modern electronics.

Thus, various operating modes of a device-under-test can be measured in a very simple and highly efficient way. The former time-consuming and complex pre-scan/final scan testing procedure is no longer needed. Visit the company’s website for additional information.
