The GSP-9330 from Good Will Instrument Co., Ltd. is a Spectrum Analyzer that operates from 9 kHz to 3.25 GHz. It has a sweep speed of 204 μs via high-speed sweep time to easily handle and analyze modulation signals. This spectrum analyzer can capture transient signals such as Tire-pressure monitoring system (TPMS), frequency/amplitude modulation signals, Bluetooth frequency hopping signals, tuned oscillator, or other interfering signals under the ISM Band. It has an analog AM/FM demodulation & analysis function and additionally provides ASK/FSK digital signal demodulation capability. 

The GSP-9330 has a resolution bandwidth of 1 Hz to 1 MHz and a video bandwidth of 1 Hz to 1 MHz. It can measure signal amplitudes up to 30 dBm and has a DANl of less than -116 dBm. It has a phase noise of less than -113 dBc/Hz and spurious signals of less than -60 dBc. This spectrum analyzer has built-in Spectrogram, Topographic & Split-Window Display modes and EMC pretest function & Quasi-Peak/Average EMI detect modes. It can measure signal parameters like P1dB point, Harmonic, CHPW, OCBW, ACPR, SEM, TOI, CNR, CTB, CSO, N-dB bandwidth, Noise Marker, Frequency Counter, TDP, and Gated Sweep. This spectrum analyzer can be controlled via RJ-45 LAN TCP/IP, USB 2.0, RS232 and GPIB interfaces. It requires an AC supply of 100-240 V and consumes less than 65 W of power. This spectrum analyzer is available in a benchtop enclosure that measures 210 x 350 x 100 mm.
