AFJ Instruments FFT Test Receivers

AFJ offers the following 4 FFT Test Receivers

Conducted Emission

• FFT 3010 – 9kHz~30MHz

• FFT 3030 – 9kHz~300MHz

Radiated Emission

• FFT 3100 – 30MHz~1GHz

• FFT 3300 – 30MHz~3GHz

FFT 3010 & FFT 3030 EMI TEST RECEIVERS FOR CONDUCTED EMISSION TESTING 

Conducted Emissions are due to a spurious current throughout a power unit harness being introducted into the common power network.
These conducted emissions exciting the device may affect other devices on the common power network.

Conducted emissions may also generate unwanted radiation.

The AFJ Instruments FFT 3010 & 3030 EMI Receivers have been especially designed for conducted emission measurement, both during EUT diagnostic development and for final compliance testing.

FFT 3010 & 3030 EMI TEST RECEIVERS

Based on a PC integrated architecture with WINDOWS 10 Embedded OS, FFT 3010 & 3030 EMI Receivers are ready to operate with advanced software for EMC testing, fitted with pre-selectors that allow excellent dynamic range and precise conducted emission measurements covering the frequency range from 9kHz to 300MHz. Remote control with an external PC is also possible.

Optimized easy-to-use EMI measurement concept. Fitted with the internal pre-selector/ preamplifier AFJ FFT 3010 & 3030 units feature an excellent dynamic range and are, therefore, able to perform precise EMC tests. Measurements to commercial EMI International, European and Product standards, shall be carried out directly by comparing the EMI spectrum with the associated limit lines and switching on the appropriate detectors.

MAIN FEATURES

digital demodulations

CISPR 16-1-1 COMPLIANCE

FFT 3010 & 3030 EMI Receivers fully comply with CISPR 16-1-1. The response of Quasi-Peak Detector in terms of both absolute calibration and relative calibration lays between the tolerances of CISPR 16-1-1. The pulse weighting conformity meets down to the minimum value of the Pulse Repetition Frequency (PRF) coming from the DUT, of 1Hz.

The FFT Scan Mode is compliant to CISPR 16-3.

Accuracy and reproducibility are key parameters for AFJ FFT 3010 & 3030 EMI Receiver application.
