The Keysight N9038B MXE EMI Receiver is a high-performance diagnostic signal analyzer engineered for electromagnetic interference compliance testing across DC to microwave frequencies. This upgradeable platform delivers rapid EMI certification with real-time spectrum analysis, time-domain scanning, and advanced diagnostics—all while maintaining compliance with CISPR 16-1-1:2019, MIL-STD-461G, ANSI C63.2, and FCC standards.
Technical Specifications
Frequency Coverage: 3 Hz to 44 GHz with optional extension points at 3.6 GHz, 8.4 GHz, 26.5 GHz, and 44 GHz.
Analysis Bandwidth: Up to 160 MHz maximum real-time bandwidth. Selectable options include 10 MHz, 25 MHz, 85 MHz, and 160 MHz. The 85 MHz real-time bandwidth enables gapless capture of transient signals.
Sensitivity & Noise Floor: Displayed Average Noise Level (DANL) at 1 GHz ranges from -163 dBm (preamplifier on) to -174 dBm (preamplifier on, optimized configuration). Phase noise measures -114 dBc/Hz at 1 GHz (10 kHz offset).
Amplitude Performance: Amplitude accuracy of ±0.5 dB at 1 GHz. Amplitude resolution reaches 0.1881 dB. Third-order dynamic range delivers 116 dB at 1 GHz with third-order intercept points of +15 to +20 dBm (1 GHz).
Resolution Bandwidth: CISPR bandwidths include 200 Hz, 9 kHz, 120 kHz, and 1 MHz. MIL-STD bandwidths span 10 Hz through 1 MHz in standard increments.
Detection Modes: CISPR detectors (quasi-peak, EMI-average, RMS-average) and measurement detectors (peak, negative peak, sample, normal, RMS, average).
– Key Features
