N9000B CXA Signal Analyzer

Master the Essentials of Signal Characterization for Industrial Communications and IoT

As the low cost, entry-level member of Keysight X-series signal analyzers, N9000B CXA signal analyzer is crafted for essential signal characterization for industrial communications and IoT. Harness the power of the X-series, and the proven measurement science, N9000B CXA is a reliable spectrum and signal analysis platform to address your versatile needs: from RF design verification, engineering, manufacturing, and repair service.

A flexible, scalable test platform for you

When you need deeper insight into your design beyond spectrum analysis – CXA protects your investment with scalable capabilities, such as analog/digital demodulation, noise figure, EMI emission, LoRa, NB-IoT signal analysis, etc. All these extended capabilities can be easily enabled by X-series applications.

Three great reasons of having a CXA signal analyzer on your bench

Superior performance adds confidence in each measurement you make

• Frequency range: 9 kHz to 3/7.5/13.6/26.5 GHz

• Internal fully calibrated preamplifier up to 26.5 GHz

• Resolution bandwidth: 1 Hz to 8 MHz

• Displayed average noise level (at 1 GHz): -163 dBm/Hz

• Third order interception (at 1 GHz): +17 dBm

• Total absolute amplitude accuracy (at 1 GHz): ± 0.5 dB

• Phase noise (1 GHz, 10 kHz offset): -110 dBc/Hz 

• Maximum analysis bandwidth: 25 MHz

Equip CXA with application software to cover your evolving testing needs:

Common Measurements Available From a CXA

RF design engineers’ ultimate goal is to ensure their radio transmitters to transmit at the right frequency with enough power, but not excessive power that may bring bad interference to other electronic devices in the neighborhood. For example, in radio transmitter test case, you primarily care about the transmission power and frequency, and how accurate they are. You also care about those harmonics, spurious and distortions that might generate internal or external interference to the whole system. If you design wireless devices, IoT devices, or medical devices, you need test your products against certain wireless standard to make sure your device follow and meet all the required specifications

Keysight N9000B CXA is primarily a general purpose spectrum analyzer, which helps you to characterize the most fundamental parameters of an wireless transmitter, such as if its center frequency, drift; output power, or occupied bandwidth; or its in-band or out-band spurious

When you add the X-series applications onto the CXA, it becomes a flexible signal analyzer, capable to characterize today’s narrow band wireless connectivity formats, such as LoRa, Bluetooth, Zigbee, NBIoT signals, WLAN 802.11 a/b/g/j/p/n/af/ah, and more custom digital modulation signals. The N9000B CXA signal analyzer is with 10 MHz analysis bandwidth as standard, and up to 25 MHz analysis bandwidth optional (option B25)
