Core Positioning: FSG High-Performance Signal Generator
The core objective of the FSG series is to generate RF and microwave signals with high quality, high purity, high stability, and highly precise parameter (frequency, power) settings. It focuses on providing "clean" analog signals.

Key Features and Advantages:
Extremely low single-sideband phase noise:

This is the most prominent advantage of the FSG series. It produces very "pure" signals with extremely low phase noise at close carrier frequency offsets. This is crucial for testing receiver sensitivity, radar system performance, and serving as a substitute for local oscillators in high-demand circuits.

Very high output power and excellent level accuracy:

It provides high output power (typically up to >+20 dBm) and highly precise level settings across the entire frequency and power range. This is particularly important for applications such as testing amplifier compression points and component losses.

Rich analog modulation capabilities:

Supports AM (amplitude modulation), FM (frequency modulation), ΦM (phase modulation), and pulse modulation. Its pulse modulation performance is especially outstanding, with extremely fast rise/fall times and very high on/off ratios, making it ideal for radar testing.

Fast frequency switching speed:

It switches between frequency points quickly, making it suitable for test scenarios requiring fast frequency hopping.

High reliability:

As a high-end instrument, its design and manufacturing standards are very high, ensuring stable operation in demanding R&D and production environments.

Model Interpretation and Application Scenarios
FSG8: Frequency range up to 8 GHz.

FSG13: Frequency range up to 13.6 GHz (or 13 GHz, commonly used in radar frequency bands).

Typical Application Areas:

Aerospace and Defense (core market):

Radar testing: Simulating radar echo signals to test radar receivers. Its excellent pulse modulation and low phase noise characteristics make it an ideal choice.

Electronic Warfare (EW): Generating complex signals for testing Electronic Support (ES) and Electronic Countermeasure (EC) systems.

Satellite communication: Serving as a local oscillator for upconverters or generating test signals.

Component testing:

Testing the characteristics of microwave components such as filters, amplifiers, and mixers, including frequency response, gain, 1dB compression point, and isolation.

General R&D:

In universities and research institutes, providing high-quality local oscillator signals or excitation signals for the development of various RF circuits and systems.
