The PSA Series Spectrum Analyzers from Keysight Technologies (formerly Agilent) are highperformance instruments designed for the analysis of radio frequency (RF) signals. These analyzers provide a wide range of applications for signal analysis and are commonly used in telecommunications, aerospace, defense, and electronic design and testing environments.

Key Features of the PSA Series Spectrum Analyzers:

1. Wide Frequency Range:

l The PSA Series typically offers models with frequency ranges from 9 kHz to 50 GHz or higher, which makes them suitable for both low and high-frequency applications.

2. High Dynamic Range:

l The PSA Spectrum Analyzers feature excellent dynamic range, typically around 100 dB or more. This ensures precise measurements of weak signals in the presence of strong signals.

3. Superior Phase Noise Performance:

l With low phase noise, the PSA series is capable of providing highly accurate signal measurements, especially important for advanced communications systems and radar applications.

4. Signal Analysis:

l They can analyze both analog and digital signals, including wideband signals and modulated signals. The PSA analyzers can also demodulate signals to help with performance analysis.

5. Advanced Measurement Capabilities:
   • PSA analyzers support a wide range of measurements, such as:
     • Occupied Bandwidth (OBW)
     • Channel Power and Adjacent Channel Power Ratio (ACPR)
     • Error Vector Magnitude (EVM) for assessing signal quality in communications systems
     • Spectrum Emission Mask (SEM)
     • Multi-standard analysis (for various wireless standards like LTE, Wi-Fi, etc.)

6. Real-Time Spectrum Analysis:
   • Some PSA models provide real-time spectrum analysis (RTSA) capabilities, allowing for the capture and analysis of transient signals or events that may be missed by traditional analyzers.
7. Built-in Analysis Tools:
   • Features like digital modulation analysis, time gating, and cross-correlation are built-in, making these analyzers suitable for complex testing and troubleshooting.
8. Signal Generator Integration:
   • Some PSA models can be integrated with signal generators, enabling users to generate test signals for creating specific test environments.
9. Touchscreen Interface:
   • Many PSA series models come with an intuitive touchscreen interface for easy operation. The user-friendly interface is complemented by remote control options via USB, GPIB, LAN, and LXI.
10. Connectivity and Automation:

These analyzers offer excellent connectivity options for remote control and automation, which is essential in laboratory and production environments for automated testing and data collection.

Common Applications:

• Wireless Communications: Testing and analysis of cellular networks (LTE, 5G), Wi-Fi, Bluetooth, and other communication technologies.
• Radar and Satellite: Useful in aerospace and defense applications for radar signal analysis and satellite communications testing.
• Broadcasting: Ensuring the integrity of radio and TV transmissions.
• Electronic Component Testing: Verifying the performance of RF components such as amplifiers, mixers, and oscillators.
