In-depth Analysis of the Keysight N9048B PXE EMI Receiver: A Revolutionary Tool for 5G and Automotive Electronics Testing
I. Product Positioning and Core Value
II. Core Technical Indicators and Performance Breakthroughs
- Basic Frequency Range : 2 Hz to 26.5 GHz (supports expansion to 44 GHz via option)
- Real-time Bandwidth : 350 MHz (supports gapless signal capture, more than 4 times that of traditional EMI receivers)
- Resolution Bandwidth : Supports dual modes: CISPR (200 Hz/9 kHz/120 kHz/1 MHz) and MIL-STD (10% step)
- DANL : -174 dBm (1 GHz, with preamplifier), more than 10 dB improvement over similar products
- Third-Order Intercept Point (TOI) : +20 dBm (1 GHz), ensuring reliable measurements in strong signal environments
- Dynamic Range : >123 dB (typical value), meeting the measurement requirements of CISPR 16-1-1:2019 for complex signals
- Time Domain Scan (TDS) : Uses FFT technology to achieve fast signal capture, reducing automotive electronics testing time from 36 hours to 200 seconds
- Accelerated TDS : Further reduces testing time to less than 24 seconds, supporting automated batch testing on production lines
III. Functional Characteristics and Industry Innovation
- Millimeter-wave Support : Covers the 5G FR2 band (24.25-52.6 GHz), and can test out-of-band radiation and spurious signals of 5G base stations
- Real-time Scan (RTS) : Simultaneously displays frequency domain, time domain, and spectrum graphs within a 350 MHz bandwidth, accurately locating transient interference of 5G NR signals
- CAN/LIN Bus Trigger : Supports joint analysis of automotive bus signals and radio frequency signals, quickly diagnosing EMI problems in ADAS systems
- Millimeter-wave Radar Testing : Built-in 77-81 GHz band templates meet the radiated emission (RE) and immunity (RS) testing needs of automotive radar
- SCPI Command Compatibility : Can simulate mainstream spectrum analyzers such as R&S FSW, seamlessly migrating existing test processes
- LXI Class C Standard : Supports remote control and automated testing, adapting to Industry 4.0 production line needs
IV. Typical Application Scenarios
- Out-of-band radiation testing of 5G base stations (supports 3GPP TS 38.104 standard)
- Phase noise assessment of radio frequency chips (built-in dedicated application)
- Radiated emission testing of automotive radar (77 GHz)
- Transient interference diagnosis of ADAS systems (such as collaborative testing of lidar and cameras)
- Wideband noise testing of satellite communication equipment (supports MIL-STD-461G)
- Harmonic suppression measurement of radar systems
- DFS channel monitoring of Wi-Fi 7 (802.11be) devices
- SAR value and radiated spurious emissions (RSE) testing of mobile phones
V. User Value and Industry Impact
- Efficiency Improvement : 350 MHz real-time bandwidth and accelerated TDS technology increase testing efficiency by more than 100 times
- Cost Optimization : Integrates the functions of an EMI receiver, spectrum analyzer, and phase noise tester, reducing equipment procurement costs by 50%
- Technological Foresight Supports amplitude probability distribution (APD) measurements in future CISPR 11 standards, protecting user investment

Applicable Scenarios : High-frequency EMI testing for automotive radar and satellite communication equipment.
3. R&D and Debugging
- N9048B-100 + N9048B-402 (Phase Noise) + N9048B-203 (RTSA)
Applicable Scenarios : Oscillator design, high-speed data link signal integrity analysis.
VII. Notes
- Millimeter-wave mixers (such as 85658B-003) need to be paired N9048B-105 and require separate calibration.
- High-frequency test fixtures (such as 11970-60005) must match the mixer interface.
- Some software options (such as N9048B-401 ) require separate authorization and activation.
- The 5G NR analysis function requires 89600 VSA software 。
- Millimeter-wave mixers (such as the 85658B series) may be subject to export controls; compliance must be confirmed in advance.
