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.
