Agilent/Keysight N6141C

The Agilent/Keysight N6141C is a software-based EMI Receiver Measurement Application that extends X-Series signal analyzer capabilities for pre-compliance radiated and conducted emissions testing. It enables engineers to perform diagnostic evaluations and identify potential emissions issues early in the design cycle, reducing the risk of costly redesigns and re-testing after full compliance certification.

– Technical Specifications

Frequency Coverage:
• Conducted emissions: 9 kHz to 30 MHz (dependent on regulatory agency)
• Radiated emissions: 30 MHz to 1 GHz, expandable to 6 GHz and higher based on DUT clock frequency

Detectors: Peak, quasi-peak, EMI average, and RMS average

Bandwidth Standards: CISPR 16-1-1 compliant bandwidths and MIL-STD bandwidths

Band Presets: CISPR bands A through E

– Key Features

• Automated testing to regulatory limit lines with user-selected margins
• Signal list feature to differentiate device under test signals from ambient noise
• Scan table configuration for frequency ranges, gains, bandwidths, and dwell time
• Log or linear frequency display
• Simultaneous detector observation at single frequencies using up to three meters
• Time Domain Scan (Optional, requires Option DP2 or B40; not available for CXA) employing high-overlap FFTs for wide-bandwidth data collection
• Monitor Spectrum function with bar meter display for maximum amplitude detection
• Amplitude Probability Distribution (APD) capability
• Amplitude correction support for antennas, LISNs, cables, and preamps
• HTML report generation

– Typical Applications

• Radiated and conducted emissions pre-compliance measurement
• Early-stage emissions diagnostics
• Design verification against CISPR 16-1-1 and MIL-STD standards

– Compatibility & Integration

The N6141C operates within Keysight X-Series signal analyzers: UXA N9040B, PXA N9030B, MXA N9020B, EXA N9010B, and CXA N9000B. It leverages the multi-touch user interface native to these platforms.
