Agilent/Keysight N9038A

The Keysight N9038A MXE EMI Receiver is a modular instrument for regulatory compliance testing of RF and microwave devices. It functions as both an EMI test receiver and diagnostic signal analyzer, supporting industry-standard compliance specifications including CISPR 16-1-1 and MIL-STD-461. The upgradeable platform delivers flexible frequency coverage and multiple detector types, making it suitable for electromagnetic interference and electromagnetic compatibility validation across diverse frequency bands.

Technical Specifications

Frequency Range:
Multiple configurations available: 3 Hz to 3.6 GHz, 3 Hz to 8.4 GHz, 3 Hz to 26.5 GHz, 20 Hz to 26.5 GHz, 3 Hz to 44 GHz, and 20 Hz to 44 GHz. Resolution Bandwidth (RBW):
1 Hz to 8 MHz with standard CISPR bandwidths of 200 Hz, 9 kHz, 120 kHz, and 1 MHz. MIL-STD and other standard bandwidths increment in 10% steps. Bandwidth accuracy: ±2% nominal from 1 Hz to 1.3 MHz. Detectors:
Quasi-peak, EMI-average, RMS-average, peak, negative peak, sample, normal, and diagnostic detector types. Dynamic Range:
Greater than 70 dB; 76 dBc at +3 dBm mixer level with up to 1 dB compression potential. Amplitude Accuracy:
±0.29 dB (20 Hz to 3.6 GHz), ±0.5 dB @ 1 GHz, ±0.75 dB to ±2.7 dB absolute amplitude accuracy. Accuracy specifications apply with ADC dither On; dither Off may degrade scale fidelity for signals around -60 dBm or lower by 0.2 dB. Displayed Average Noise Level (DANL):
-163 dBm with preamplifier; -166 dBm at 1 GHz with preamplifier and noise floor extension; -167 dBm with preamplifier and noise floor extension. Third-Order Intercept (TOI):
+15 dBm at 1 GHz; typical range +12 dBm to +16 dBm depending on frequency. Phase Noise:
-103 dBc/Hz to -114 dBc/Hz at 10 kHz offset at 1 GHz center frequency. Analysis Bandwidth:
Maximum 25 MHz with Option B25; real-time bandwidth up to 85 MHz.
