GSP-9330 is a 3.25GHz high-speed testing spectrum analyzer
GSP-9330 is a 3.25GHz high-speed testing spectrum analyzer with a maximum scanning speed of 204uS. Users can easily process and analyze modulated signals by quickly scanning the time. The key to modulation signal processing is the fast scanning 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, EMC's issues are critical to the product design process. Therefore, the GSP-9330 incorporates EMC predictive solutions to facilitate EMC testing. The GSP-9330's simple EMC forecasting process greatly shortens user product launch time.
A. Fast signal scanning
Speed is an important specification for a spectrum analyzer. The GSP-9330 provides scanning speeds of up to 204us. Users identify and analyze various fast or transient signals through rapid scanning times. Such as frequency/amplitude modulation 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 transmission rate RF communication applications due to its low design cost and low power consumption. Today, 2FSK modulation technology is used in a large number of different products and systems, such as consumer electronics, automotive electronics, RFID, automatic reading meters, and industrial control devices. The parameters that can be measured by FSK analysis include carrier power, FSK frequency offset, and carrier frequency&carrier frequency offset measurements. The user can set judgment conditions on frequency offset and carrier offset to quickly determine the test results.
Amplitude Shift Keying (ASK) is often used in RFID and optical communication systems, while Frequency Shift Keying (FSK) is used in many applications such as wireless telephony, paging systems, and RFID. ASK/FSK demodulates and analyzes measured parameters, including amplitude modulation depth, frequency offset, carrier power and frequency offset, symbol code, and waveform. The user can set the pass/fail test results for amplitude modulation depth, frequency offset, carrier power, and carrier offset. It also provides a function to determine the preamble&sync for data messages.
AM/FM signal analysis measures parameters, including amplitude modulation depth, frequency offset, modulation rate, carrier power, carrier frequency offset, and SINAD. The user can set judgment conditions for amplitude modulation depth, frequency offset, carrier power, and carrier offset to quickly test the results. The AM/FM demodulation function can demodulate and listen to AM or FM broadcast signals.

C. EMC Pre Diagnostic Testing Solution
GSP-9330 has a built-in EMI dedicated 200/9k/120k/1MHz filter, a 20dB low noise amplifier, and a Quasi-Peak/Coverage detection mode. Users can perform the required tests in the EMC Pretest function on the machine, and can also match the kit for radiation and conduction tests.
The radiation testing kit, GKT-008, provides a complete combination of near-field measuring rods, which can simplify complex measurements and simulate 3m/10m far field testing in a laboratory, greatly saving engineers' time and expenses for debugging and commuting to and from the laboratory; It can also be used with the Tracking Generator function of GSP-9330 for EMS testing.
For conducting tests, LISN and Isolated Transformer can be used to measure electromagnetic conduction. If you are concerned about large or complex voltage variations at the terminals to be tested, you can also use Transient Limiter to make the test equipment safer.
