Keysight / Agilent N9000A 3GHz CXA Signal Analyzer w/Low PHASE NOISE ~ CAL'D!!

Keysight N9000A 3GHz CXA Signal Analyzer w/ Option EP4 (Enhanced Phase Noise) -

This option greatly outperforms the mxa in phase noise from close in to the midrange offsets. Improvement up to 15 dbm from the mxa so imagine how much improvement it is for the cxa with inherently more phase noise than mxa! It's an incredibly good option!

And tons more!

Phase noise measurement, noise figure, EMC, vector signal analysis, flexible digital demod, etc....

Excellent Condition! Keysight (formerly Agilent) N9000A CXA Signal Analyzer configured for 3GHz frequency range with the premium Option EP4 for enhanced low phase noise performance. This unit is in excellent working condition, perfect for RF engineers, labs, or test environments needing reliable spectrum analysis with superior noise characteristics. Lightly used in a professional setting – no major scratches or dents, fully functional and calibrated recently. Don't miss this chance to own a versatile Keysight analyzer at a fraction of the new price!Key Features and Specifications: Frequency Range: 9 kHz to 3 GHz (Option 503) – ideal for a wide array of applications including Bluetooth, GSM/EDGE, W-CDMA, LTE FDD, digital cable TV, DVB-T/H, ISDB-T, CMMB, and DTMB. Option EP4 (Enhanced Phase Noise): Delivers top-tier low phase noise for precise measurements. At 1 GHz center frequency: 10 kHz offset: -102 dBc/Hz (specification), -110 dBc/Hz (typical). 100 kHz offset: -108 dBc/Hz (specification), -110 dBc/Hz (typical). 1 MHz offset: -130 dBc/Hz (specification).This option significantly improves dynamic range and sensitivity, with Displayed Average Noise Level (DANL) as low as -150 dBm (typical) from 10 MHz to 1.5 GHz, making it excellent for demanding signal analysis where noise floor matters. Analysis Bandwidth: Standard 10 MHz, with optional upgrade path to 25 MHz for broader signal capture. Dynamic Range: Third Order Intercept (TOI): +15 dBm at 1 GHz, +14 dBm up to 26.5 GHz (scalable). Superior ACPR for W-CDMA: -73 dB (typical) at 5 MHz offset, -78 dB at 10 MHz (with noise correction). GSM/EDGE Output RF Spectrum: Up to 74.3 dB at 1.2 MHz offset. Other Notable Specs: Absolute Amplitude Accuracy: ±0.61 dB (95th percentile). Preamplifier Option (P03): +20 dB gain for low-level signals. Built-in measurement applications for analog demodulation, phase noise, and more. Interfaces: GPIB, LAN, USB for easy integration. High-performance processor: Single-core with 4 GB RAM and removable SSD. Condition: Excellent – LIKE NEW powers on without issues, display is bright and clear, all buttons and ports function properly. Recently serviced and calibrated (certificate available upon request). What's Included: Keysight N9000A main unit with Option 503 (3GHz) and EP4 (Enhanced Phase Noise). Power cord. FRESH NIST CALIBRATION. Note: No additional accessories like probes or cables included unless specified – contact me if you need recommendations.Why Buy This? This analyzer is a workhorse for spectrum monitoring, EMI testing, and wireless development. The EP4 option sets it apart by providing cleaner phase noise measurements, reducing errors in high-precision tasks. Comparable new units cost thousands more – grab this one and elevate your test setup!

For highercoverage, we recommend using our preferred carriers. To get the most accurate shipping quote, reach out to us beforehand so wecan determine the best price based on your destination and preferences. Duties, Taxes, and Tariffs: All international buyers are fully responsible for any inbound duties, taxes, and tariffs imposed by their country. With ongoing global trade tensions (including recent U.S. tariffexpansions in 2025 on imports from various countries, such as 10-40% on electronicsdepending on origin and destination), tariffs on certain electronic test equipment may apply. If you're unsure, please email us for the Country of Origin (COO) details to help you assess potential costs. All such charges are100% the buyer's responsibility. Additional eBay Fees: eBay now applies an international transaction fee ofapproximately 1.65% on cross-border sales (varying slightly by buyer'scountry), which we regrettably must pass on to you.
