Digital oscilloscopes have entered an epoch-making generation. Innovative design, compact appearance, and abundant functionalities together forge this simple-in-look oscilloscope a very powerful test and measurement instrument which facilitates engineers to easily solve complex measurement issues. This is the latest definition of digital oscilloscope defined by GDS-1000B. The GDS-1000B series demonstrates the impeccable functionalities with an extremely ordinary pricing, which allows customers to realize the true meaning of bigger bang for the buck. Although, the GDS-1000B series is under the category of general purpose oscilloscope, the full functionalities within this simple-in-look oscilloscope, including parameter measurement, cursor indication, digital voltage meter, and data logging, surpasses the same category 1000 series oscilloscopes in the market. All applications of the GDS-1000B series can be applied to the educational field and the fundamental R&D units of the industrial sector.

The GDS-1000B series features three bandwidth selections  100 MHz, 70 MHz, 50MHz and equips with analog signal input terminals by four or two channels ( 50MHz only equipped 4 channels input ). The maximum sampling rate for each single channel is 1GSa/s, and the memory depth is 10Mpts per channel independently. The waveform update rate is 50,000wfms/s, which helps users to precisely observe the detailed waveform variation. Additionally, 7” WVGA color LCD display and the 256 color gradient display function together allow waveforms to be observed with the senses of transparency and gradation. With respect to the horizontal time scale adjustment knob and trigger level adjustment knob, GW Instek provides a very thoughtful design the zero key function, which allows engineers to work more effectively.

For mathematical analysis mode, 1Mpts FFT signal display makes the dull frequency domain signal analysis more delicate. Diversified trigger functions, X-Y mode analysis, and Go/NoGo function arm the GDS-1000B series oscilloscope with higher level measurement technologies. The GDS-1000B series oscilloscope also provides OpenWave connection software, which allows users to conduct waveform observation and data storage controlled by remote PC. Moreover, the innovative exterior design and compact design also bring much convenience to users. Other diversified and charming multi-functional operation demonstrates the concept of complete technology integration.
