Radiated emission measurement and analysis software which eliminates oversight of noise during measurements
-
What is EPX/RE?This is the world’s first software with an entirely new concept that enables reliable automatic measurements of radiated emission without overlooking any noise by using the Accelerated Time Domain Scan capabilities of EMI receiver. The EMI receiver, path switcher, antenna mast, turntable, and other components that make up a radiated emission measuring system are controlled to automatically measure and analyze electromagnetic noise from home electrical appliances, medical devices, and other electronic devices.

Technologies to support highly reliable measurements without overlooking any noise
Automatic measurement sequences incorporating Real Time Scan・No noise is overlooked due to gapless measurements that constantly monitor the spectrum within the FFT bandwidth.
・The 30-1,000 MHz band can be measured in only three ranges. -
Pre-scanning using a QP detector・By accurately capturing the characteristics of broadband noise, EPX/RE accurately narrows down the frequency points to be measured from within a wide bandwidth.
・Because the FFT bandwidth of 350 MHz is maintained even for QP detector measurements, the short measurement time remains unchanged. -
EPX/RE analyzes noise characteristics and automatically sets the appropriate monitoring time.・Pre-scanning analyzes the temporal behavior of noise, and automatically calculates the Dwell Time to match the noise periodicity.
・Stable noise can be measured quickly, and intermittent noise can be measured with sufficient monitoring time, in order to enable accurate final measurements. -
Other features
Eliminating the effects of impulse noise which covers a wide band・Even if the entire FFT bandwidth is covered by impulse noise in measurement with a PK detector / Maxhold, the influence can be removed using filtering.
-
The temporal behavior of noise is also analyzed.・Since all the measured data from the EMI receiver are acquired, it is possible to analyze temporal changes in the noise level at each frequency point.
・This is very effective for identification of noise sources and taking countermeasures, because the interval and frequency of the noise can be visualized. -
Recommended configuration
Synergy with Keysight Technologies' latest EMI-receiver, the N9048B PXESynergy with Keysight Technologies’ latest EMI-receiver N9048B PXE EPX/RE functionality is maximized by combining it with N9048B PXE, an EMI-receiver with a Accelerated Time Domain Scan function with a 350 MHz FFT bandwidth.
