GW Instek GSP-730 Spectrum Analyzer


GW Instek GSP-730 is a 3 GHz Spectrum Analyzer mainly developed to fulfill the demands of RF Communication educations. Budget constraint and insufficient teaching tools are normally the two hurdles for schools to provide high-quality courses for RF communication experiments. A moderate spectrum analyzer, GSP-730, featuring full functions should provide, along with GRF-1300 training kit possesses a unique position in the field as an economic turn-key solution for 3GHz RF Communication Experiment courses.

With its components, GSP-730 Spectrum Analyzer, GRF-1300 Trainer and a PC, properly connected, a tangible system is integrated for performing ongoing experiments while the lecture is given. Using a PC, the teacher can present teaching material with PowerPoint slide and simultaneously control GSP-730 and GRF-1300 to perform experiments and get spectrum displays and parameter readings on the PC screen. GSP-730 and GRF-1300 easily transferred the current teaching materials, including the PowerPoint slides, textbook, and a remote control software, into electronic-teaching system.

The combination of GSP-730 and GRF-1300 forms a fundamental training system for RF communication and telecommunication classes in the universities, colleges, vocational schools, and the training centers in military as well as private companies. Instead of the tremendous cost of the installation of new training system, the conjunction of GSP-730 and GRF-1300 provides an economic solution to eliminate two obstacles, budget constraint and insufficiency of teaching tools.

A Turn-Key Solution to Clear Away Two Obstacles

GSP-730, carrying 3GHZ bandwith and measurement functions including Autoset, Split Window, Limit Line, ACPR and OCBW etc., is regarded as the advanced educations of Mobile Communications (GSM, 3G, 4G/LTE…), Wi-Fi, Zigbee and RFID in the Electronic or the Communication classes. The USB ports, the RS-232 interface and the VGA video output facilitate the teaching efficiency. The combination of GSP-730 and GRF-1300 RF communication training is a turn-key system for both lecture and hands-on training purposes.

GRF-1300 RF communication trainer, as the counterpart GSP-730 for the basic RF communication experiment system, is capable of generating a baseband signal and a RF carrier signal for the built-in AM and FM communication operations. The baseband signal output contains the selections of Sine, Triangle, and Square waveforms in the frequency range of 100kHz ~ 3MHz, whereas the RF signal output is a frequency-variable Sine wave in the range of 870 ~ 920 MHz. Connecting the baseband signal output with AM or FM inputs on the panel, GRF-1300 produces AM or FM signal output respectively by using the internal RF signal as the modulation carrier according to user’s selected frequency.
