Product Description The N9020A MXA is a mid-performance signal analyzer designed to bridge the gap between basic spectrum analysis and high-end research-grade instrumentation. As part of the X-Series signal analyzers, it offers high-speed data acquisition and a wide dynamic range, making it an industry standard for wireless communication testing. It features an intuitive touch-screen interface and is compatible with Keysight’s 89600 VSA software for advanced vector signal analysis. Its LXI (LAN eXtensions for Instrumentation) compliance ensures seamless integration into automated test systems and remote monitoring environments.

Product Applications The N9020A is extensively used in the design, characterization, and manufacturing of wireless devices. It is ideal for analyzing complex modulated signals such as LTE, W-CDMA, and 5G NR (with appropriate options). Engineers utilize the MXA for troubleshooting interference, measuring harmonic distortion, and performing adjacent channel power (ACP) tests. Its broad frequency range up to 26.5 GHz makes it suitable for aerospace and defense applications, including radar testing and satellite communication link verification.

Operational Precautions

• RF Input Protection: Never exceed the maximum RF input power (typically +30 dBm or 1 Watt); using external attenuators is mandatory when measuring high-power transmitters to prevent permanent damage to the sensitive front-end mixer.
• ESD Safety: Before connecting any cable or device under test (DUT) to the RF input, ensure both the instrument and the operator are properly grounded to prevent electrostatic discharge from destroying the input circuitry.
• Calibration Cycle: To maintain the high absolute amplitude accuracy of ±0.23 dB, the unit should be calibrated annually by an authorized service center.
• Airflow Management: Do not block the cooling vents on the sides and rear of the instrument. Excessive heat can lead to frequency drift and premature failure of the internal power supply or processing boards.
