There are also more than 20 measurement applications such as AM/FM modulation signal analysis, signal channel analysis, CATV parameter testing, and with the TG option, it can be used to test the frequency response or power linearity of components.
Signal monitoring and processing part, GSP-9300B provides Topographic display mode, the use of color temperature can distinguish between continuous or occasional signals; Spectrogram mode is the spectrum of the display coupled with the display of the time axis, you can observe the frequency of the signal in the time of the change in the situation, and dual-window mode can be used for the two windows for the individual parameter settings; in addition to The Spectrogram mode is a spectrum display with a time axis display for observing the signal frequency and time changes, while the Dual Window mode allows you to set parameters for both windows individually. In addition, it provides user-friendly interfaces, such as status icon display, on-line instructions, multi-language support, and quick storage.
In addition, the GSP-9300B provides convenient settings for production line environments, providing pre-set power-on time, sequence function and limit line measurement...etc. Through the patented thermal conductivity design, it significantly reduces the time needed for warm-up and accelerates the production process; in the choice of equipment, it provides signal tracker, carrying bag, battery module, EMI antenna set and rack In terms of equipment options, we provide signal tracker, battery module, EMI antenna set and rack accessories, no matter it is out of the test or constructed on the automatic test system, the lightweight design can meet a variety of fields.
In summary, the GSP-9300B is a stable, lightweight and suitable test equipment for a variety of applications in the education market, production line environments, general purpose signal monitoring and so on.
