Instek GSP-730 Experiment 1: Basic operation of a spectrum analyzer

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.

An Experiment Textbook (student's book) is available as the standard accessory of GRF-1300 to provide experiment courses. The curriculum of the textbook includes the introduction of the frequency domain and the time domain concepts, the operation theories of a spectrum analyzer, and nine experiments to perform hands-on training for the learning of basics RF communication theories and the RF measurement techniques using a spectrum analyzer. A CD, containing power-point slides for course presentation and the remote-control software for expreriment, is attainable with GRF-1300, allowing teacher to give lecture of experiment theories and perform experiment simultaneously.

Another Experiment Textbook (teacher's book) is accessible as an optional accessory of GRF-1300, in addition to the same contents in the student's book, this book provides the experiment results to the questions and as well as some advanced experiment theories. Thus, a section of test-for-learning outcomes can also be seen in the lecturers' material in order to guide the students from the faulty diagnosis to the correct one in a RF communication circuitry. On the GRF-1300 panel, there are five test points set at different joints of circuit blocks. Through turning on or off the corresponding relays of the five test points enables the teachers to simulate the faults and teach students diagnosis technique.

The economic solution of GSP-730 and GRF-1300 greatly lowers the budget barriers for providing fundamental RF Communication Educations and facilitate the establishment of RF communication experiment labs with more training stations in schools.

hi, my name is johan and i just buy a spectrum analyzer gsp 730 . at starting, i see a white screen with some vertical colored lines 2 to 3 second and after a correct screen appear with all parameters and line green (noise floor). it is my first spectrum analyzer for learning and seeing sigal radio and modulations .is it firmware to update ? system display vers :1.17 17.12.13 . Somebdy can help me ...thanks .Johan F5IQX ..

🇺🇸🐔👍🏻😷 ATTENTION WORLD .... BUY YOUR TEST SHIT FROM THESE GUYS !!
I bought my first Rigol DSA815tg from them over 7 years ago.
The have the best prices / fastest shipping / great follow up service.
They talked an idiot I “know” through the process of tuning a repeater duplexer on the phone.
Now THAT’S service!

And... NO ... they did not pay me for this ringing endorsement.
I tried to get them to... they just wouldn’t. 😆🤣
