1-GHz TDS upgrade triples EMI test speed

The Keysight N9048B PXE EMI test receiver, paired with a standalone stream processing unit (SPU), delivers real-time, gapless 1-GHz time domain scan (TDS) bandwidth. With the SPU upgrade, the receiver covers 30 MHz to 1 GHz in a single step—down from three in the previous version—tripling EMI test speed. Together, the units enable faster, more accurate EMI testing.

With 1-GHz FFT bandwidth, the system accelerates EMI scans by covering the CISPR C and D bands in a single pass and supports user-selectable resolution bandwidths of 9 kHz, 120 kHz, and 1 MHz. Real-time, gapless capture ensures no transient events are missed, while high sensitivity and wide dynamic range reveal signals close to the noise floor.

The test setup shortens troubleshooting time from hours to minutes and fully complies with CISPR 16-1-1:2019 requirements. Additionally, the standalone SPU provides a path for future upgrades, offering long-term flexibility.

The Keysight N9048B PXE EMI receiver will be showcased at Techno-Frontier 2025 in Tokyo at the TOYO booth. Learn more about the N9048BSPU stream processing unit by viewing the flyer here.
