The key to modulated signal processing is the fast scan time and signal demodulation function. In addition to analog AM/FM demodulation and analysis functions, the GSP-9330 also provides demodulation and analysis functions for ASK/FSK and 2FSK digital signals. Today, the issue of EMC is critical to the product design process. Therefore, the GSP-9330 incorporates an EMC prediction solution to facilitate EMC testing. the GSP-9330's easy EMC prediction process dramatically reduces the time to product release for users.
A. Fast signal scanning
Speed is an important specification for spectrum analyzers, and the GSP-9330 offers scanning speeds of up to 204us. The fast scan time allows the user to identify and analyze a variety of fast or transient signals. Such as frequency/AM signals, Bluetooth frequency hopping signals, tuned voltage controlled oscillators or other interference signals in the ISM band.

B. Modulated signal analysis
2FSK modulation is widely used in low power and low data rate RF communication applications because of its low design cost and low power consumption. Today, 2FSK modulation technology is used in a wide variety of products and systems such as consumer electronics, automotive electronics, RFID, automatic meter reading and industrial control devices, etc. 2FSK analyzer can measure parameters such as Carrier Power, FSK Bias, Carrier Frequency & Carrier Frequency Offset measurements. Users can set the judgment conditions on the frequency deviation and carrier offset to quickly determine the test results.
RFID and optical communication systems often use Amplitude Shift Keying (ASK), while wireless phones, paging systems and RFID and many other applications use Frequency Shift Keying (FSK). ASK/FSK demodulates and analyzes the measured parameters, including amplitude depth, frequency offset, carrier power and carrier frequency shift, symbol code and waveform. The parameters measured for ASK/FSK demodulation and analysis include AM depth, frequency offset, carrier power and carrier frequency offset, symbol code and waveform. User can set pass/fail test results for AM depth, frequency offset, carrier power and carrier offset. It also provides preamble & sync function for data message.
AM/FM signal analysis measurement parameters, including AM depth, frequency deviation, modulation rate, carrier power, carrier frequency offset, and SINAD.Users can set the judgment conditions for AM depth, frequency deviation, carrier power, and carrier offset for quick test results.AM/FM demodulation function can demodulate and listen to AM or FM broadcast signals.

For the conductivity test, LISN and Isolated Transformer can be used to measure the electromagnetic conductivity. If you are worried about the voltage fluctuation of the test terminal is large or complicated, Transient Limiter can be used to make the test equipment more secure.
Spectrum Analyzer is the English word for Spectrum Analyzer.Abbreviation: SpectrometerThe
Spectrum Analyzer Principle
Broadly speaking, the signal spectrum is the total set of all frequency components that make up the signal; narrowly speaking, the amplitude spectrum that varies with frequency is often referred to as the spectrum in general spectrum measurements.
Spectral Measurement: Measurement of each frequency component of a signal in the frequency domain to obtain multiple parameters of the signal.
