The N9048B from Keysight Technologies is a PXE EMI Test Receiver that operates from 1 Hz to 44 GHz. This receiver is specifically designed for EMI compliance testing. It complies with the essential requirements of standards such as IEC/EN 61326-2-1, CISPR 11, Group 1, Class B, and IEC/EN 61010-1. This receiver comes with an RF-preselector and LNA designs and also has a built-in pre-amplifier that maximizes its overall measurement sensitivity. It has a low overall test duration and performs signal capture and analysis with Real-Time Scan (RTS) capabilities up to 350 MHz. 

The N9048B has an analysis bandwidth of 10 MHz, a dynamic average noise level (DANL) of -174 dBm, and a phase noise of -114 dBc/Hz at 10 kHz offset (center frequency, 1 GHz). It has an intuitive multi-touch user interface and is powered by Keysight’s Path wave X-series software. This receiver can be easily configured with additional features and capabilities to expand testing applications. It is available in an enclosure that measures 21.9 x 16.8 x 7.0 inches with SMA-female and BNC-female connectors.

The test receiver requires an AC supply of 100/120/220/240 V and consumes 630 W of power during active mode.
