GSP-9330 - Spectrum Analyzer 9 kHz to 3,25 GHz

Test Faster. Launch Sooner.

The all-new GSP-9330 Spectrum Analyzer, with a frequency range up to 3.25 GHz, is engineered for high-speed measurement environments. Featuring an ultra-fast sweep time of up to 204 μs, it enables users to efficiently capture and analyze transient and modulated signals with exceptional precision.

Fast sweep capability combined with advanced demodulation functions makes the GSP-9330 a powerful solution for both analog and digital signal analysis. In addition to AM/FM demodulation and analysis, the instrument supports ASK/FSK digital demodulation, as well as comprehensive 2FSK analysis—ideal for low-cost, low-power wireless applications.

Recognizing the growing importance of EMC compliance during product development, the GSP-9330 integrates a complete EMC pretest solution. Its streamlined procedures help engineers identify and resolve potential issues early, significantly reducing development time and accelerating product launch cycles.

Fast Sweep Speed — Up to 204 μs

Measurement speed is a critical performance parameter in modern RF testing. With sweep speeds as fast as 204 μs, the GSP-9330 allows users to reliably capture short-duration and transient signals, including:

• Tire Pressure Monitoring System (TPMS) signals
• Frequency and amplitude modulated signals
• Bluetooth frequency-hopping signals
• Tuned oscillators
• Interference signals within the ISM band

The high-speed sweep function ensures accurate analysis in dynamic signal environments.

Advanced Modulation Signal Analysis

Effective modulation analysis depends on both rapid sweep performance and robust demodulation capabilities. The GSP-9330 delivers:

• Analog AM/FM demodulation and analysis
• Digital ASK/FSK demodulation
• Complete 2FSK modulation analysis for widely used low-power wireless systems

These capabilities make it an ideal instrument for R&D, validation, and troubleshooting of modern communication devices.

Integrated EMC Pretest Solution

The GSP-9330 supports EMC pre-compliance testing during product development and validation stages. Early detection of electromagnetic compatibility issues helps reduce redesign cycles, lower compliance costs, and accelerate time to market.

Key EMC features include:

• Dedicated EMI filters: 200 Hz / 9 kHz / 120 kHz / 1 MHz
• 20 dB low-noise amplifier
• Quasi-Peak and Average detection modes
• Support for radiated and conducted emission measurements when used with appropriate probe sets

Near-Field and Conducted Testing Solutions

GKT-008 Radiation Test Probe Set
The GKT-008 near-field probe set simplifies complex radiated emission measurements and enables simulation of 3 m and 10 m far-field tests within a laboratory environment. This significantly reduces debugging time and minimizes the need for repeated external lab testing.

When combined with the GSP-9330 Tracking Generator option, the GKT-008 also supports EMS pre-compliance testing.

Conducted Emission Testing
For conducted emission measurements, the GKT-008 can be used in conjunction with a LISN and an isolation transformer.

In applications where the Equipment Under Test (EUT) involves high voltage variation or complex electrical conditions, the use of a transient limiter is recommended to ensure maximum protection of the test equipment.
