GSP-9300 - Spectrum Analyzer 9 kHz to 3 GHz

GSP-9300B Spectrum Analyzer

Practical, Affordable, and Reliable

The GSP-9300B is a 3 GHz spectrum analyzer designed to meet essential RF measurement requirements with precision and efficiency. It offers outstanding frequency stability of 0.025 ppm and an aging rate of 1 ppm/year, ensuring reliable long-term performance. Equipped with a built-in preamplifier and a low noise floor of –149 dBm/Hz, the GSP-9300B supports more than 20 measurement applications, including AM/FM modulation analysis, channel analysis, and CATV parameter testing.

When equipped with the optional Tracking Generator (TG), the instrument enables frequency response and power linearity testing for RF components, making it a versatile solution for development and validation environments.

Advanced Signal Monitoring and Display Capabilities

For signal monitoring, the GSP-9300B offers multiple advanced display modes:

• Topographic Display Mode: Uses color intensity to differentiate continuous and intermittent signals.
• Spectrogram Mode: Adds a time axis to the spectrum display, enabling analysis of signal variation over time.
• Split-Window Mode: Allows independent parameter settings for each display window for enhanced comparative analysis.

The user interface is designed for efficiency and ease of use, with multilingual support, built-in help functions, multiple display configurations, and fast data logging capabilities.

Connectivity and Software Integration

The GSP-9300B supports a wide range of interfaces, including:

• USB
• RS-232
• LXI
• MicroSD
• GPIB (optional)

A dedicated PC software package with IVI driver support ensures seamless integration into automated test systems.

Designed for Production Efficiency

The GSP-9300B incorporates features specifically tailored for production line environments, including:

• Auto wake-up function
• Sequence testing
• Limit line testing

Its patented thermal conduction design significantly reduces warm-up time, accelerating production workflows. The compact form factor makes it suitable for both field applications and automated test system integration.

Available options include a tracking generator, carrying bag, EMI antenna set, and rack-mount accessories.

Frequency Stability: 0.025 ppm

As wireless communications continue to expand and spectrum congestion increases, precise frequency measurement becomes critical. The GSP-9300B provides 0.025 ppm frequency stability and a 1 ppm/year aging rate—performance levels typically found in higher-end test and measurement equipment.

Built-in Preamplifier

Measuring low-level RF signals is a common challenge during product development. The integrated preamplifier delivers a noise floor down to –149 dBm/Hz. When used with the built-in EMI filter and compatible near-field probes, the GSP-9300B also supports EMI testing and troubleshooting applications.

Over 20 Integrated Measurement Functions

The GSP-9300B includes a comprehensive suite of signal processing and measurement functions:

• AM/FM modulation analysis
• Channel analysis
• CATV parameter testing
• Signal stability characterization
• Frequency response testing (with TG option)
• Power linearity testing (with TG option)

Many competing instruments in the same category offer limited functionality as paid options. In contrast, the GSP-9300B provides an extensive set of standard built-in measurement capabilities, delivering exceptional value for educational institutions, production lines, and general RF signal monitoring applications.

Compact, stable, lightweight, and cost-effective, the GSP-9300B is an ideal solution for budget-conscious users seeking professional-grade performance.
