The Instek GDS1102B digital storage oscilloscope is equipped with 100MHz bandwidth and 2 analog input channels that provide entry level users with diversified selections. The GDS-1102B 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-1102B is under the category of general purpose oscilloscope, it provides full functionalities within this simple-in-look oscilloscope, including parameter measurement, cursor indication, digital voltage meter, and data logging. All applications of the GDS-1102B can be applied to the educational field and the fundamental R&D units of the industrial sector.
The GDS-1102B's 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, a 7" WVGA color LCD display and the 256 color gradient display function together allowing 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.
WAVEFORM UPDATE RATE UP TO 50,000wfms/s and VPO Display Technology
The GDS-1102B allows users to input a rapid frequency modulation carrier signal as shown on the diagram. An unsmooth temporarily holding phenomenon will occur while using conventional digital oscilloscopes to measure this signal. As a result, the conventional digital oscilloscopes could not clearly yield the modulation variation process of frequency modulation signals. With the GDS-1102B, the measurement result will produce not only a smooth waveform modulation variation, but also detailed changes by distinct layers. Engineers can easily grasp the root cause of electric circuits while measuring the unexpected and fast changing signals. The GDS-1102B is indeed an excellent debugging weapon for the test and measurement industry.
10M MEMORY DEPTH PER CHANNEL INDEPENDENTLY
The GDS-1102B oscilloscope has a powerful and incomparable memory depth for the data retrieving. 10M memory depth per channel independently surpasses the specification of the industry's 1000 Series boundary. 10M memory depth allows users to easily seize the waveform detail while conducting fundamental measurement applications. If a long serial sequent sine waveform is input and the time scale is adjusted to 1mv/div, other GDS-1000 Series oscilloscopes for lack of sufficient memory depth will appear a distorted waveform while enlarging the waveform for its details. The GDS-1102B while enlarging the waveform to 20ns/div reveals a very clear sine waveform detail which is precisely the true value of the GDS-1102B oscilloscope.
1M FFT MATHEMATICAL SAMPLING ANALYSIS MODE
The GDS-1102B oscilloscope, under the Fast Fourier Transform mathematical analysis mode, is equipped with the 1M memory depth retrieving mode. For the conventional digital oscilloscopes, the FFT mode often has only 1000 point retrieving length; therefore, they can not show the strength distribution of each spectrum quantity under the frequency domain mode. The GDS-1000B Series oscilloscope leads the industry to provide the display mode of 1M retrieving points, which can clearly show the detail of each spectrum quantity. On top of that, the 50,000 wfms/s waveform update rate augments the FFT analysis mode to be fast and precise as if a real time spectrum analyzer is used. These features substantially elevate oscilloscope's signal processing capability for the frequency domain analysis.
ZOOM IN/PLAY AND PAUSE FUNCTION
The GDS-1102B provides engineers with partial waveform zoom in function to observe waveform in great details. The display screen can be split into two windows: the upper window shows waveform data log in a long period of time and the marked vicinity of the waveform needed to be zoomed in; the lower window shows the enlarged partial waveform. The function not only allows engineers to make a comparison but also grasp waveform details in the different timeframe. Additionally, the GDS-1102B also features the play/pause function. For the long waveform observation, the play/pause function facilitates engineers to rapidly skim through the whole section of DUT's waveforms as well as to swiftly identify waveform's problems.
X-Y MODE DISPLAY
The GDS-1102B oscilloscope provides the educational market with some powerful measurement functions. Among them, the X-Y mode display is an excellent example. Teachers and students can use X-Y mode display to conduct Lissajou diagram teaching, which allows users to easily understand the relation between waveforms and frequency while measuring sine waveforms with different frequency by dual channels. For engineers working in the industry, the X-Y mode display can be used to conduct yield rate tests for basic components' electric conduction and non conduction. Therefore, the X-Y mode display plays an important role in basic oscilloscopes.
Go/NoGo testing function allows the user to check whether the incoming signal violates the user-defined template for examining waveforms. Users can easily define this template by setting the tolerance ratio to determine violation conditions. The function can freely adjust the size of template. A defect message will be shown if the DUT’s waveform is abnormal and touches the template. The function is not only a very useful measurement tool for production lines but also a very convenient tool for engineers to observe waveforms in a long period of time.
36 MEASUREMENT PARAMETER SELECTIONS
The GDS-1102B oscilloscope is equipped with 36 different automatic measurement parameter functions. After obtaining measured waveforms, users can select different measurement parameters from the Measure key, depending on the measurement requirements. The GDS-1102B simultaneously shows eight sets of different measurement parameters on the bottom of the display screen. Users can also select the option to show all parameters, if the preset eight sets are insufficient. Once the selection is made, all 36 measurement parameters will be shown on the center of the display screen.
