Deskripsi

GW Instek GDS-2000E Series Digital Storage Oscilloscopes

The GDS-2000E Series features bandwidth selections of 200MHz, 100MH, and 70MHz. 4 channel models of the series provides 1GSa/s max.real-time sampling rate ;2 channel models of the series provides 1GSa/s per channel real-time sampling rate .All series is equipped with waveform update rate of 120,000 wfm/s. The 8-inch 800 x 480 16 : 9 TFT LCD display and the minimum 1mV/div vertical range allow the GDS-2000E Series to clearly display complex and random waveforms.

With respect to the memory depth, the standard GDS-2000E Series digital oscilloscope provides 10M long memory for users to completely retrieve and analyze waveforms. Users, base upon the application requirements, can select 1K, 10K, 100K, 1M or 10M memory depth. Short memory depth allows users to observe fast-changing waveforms and, on the other hand, long memory depth aims for continuously changing waveforms. The GDS-2000E Series is equipped with waveform search and segmented memory functions to expand the flexible applications of 10M long memory. With the waveform search function, users can rapidly search waveforms according the required trigger conditions. The segmented memory can be divided the maximum into 29,000 sections for users to bypass any unimportant waveforms so as to swiftly search all required waveforms. Memory depth provides users with the optimized applications. The waveform update rate of 120,000 wfm/s, twice as fast as that of the same category oscilloscopes, allows users to easily observe random signals so as to completely measure and test signals.

With respect to test and measurement items, the GDS-2000E Series provides 36 items and the statistics function, which allows users to analyze the maximum, the minimum, mean value, and standard deviation of the test and measurement item. Users, via the data log function, can set time and interval for waveform observation to achieve the long record objective. The GDS-2000E Series also provides 1M max. FFT display. High resolution FFT display, high waveform update rate, Window Zoom and Peak Search allow users to obtain more accurate and efficient test and measurement results while conducting tests in the frequency domain.

In addition to waveform search and segmented memory functions, the GDS-2000E Series also provides bus decoding function and digital filter function. With bus decoding function, users can not only analyze I C, SPI, and UART bus but also CAN, LIN bus, 2 which are often used for automobile communications. Digital filter allows users to independently set high pass or low pass digital filter frequency for each channel. By so doing, the observation for the signals of the specific frequency bandwidth becomes easier, and magnetic noise can be filtered out from the magnetic component while conducting power supply test applications.

The GDS-2000E Series features automatic zero key for horizontal, vertical and trigger level. Users can rapidly zero all data by simply pressing the zero key. The communications interface provides USB Host port, Device port, Ethernet communications interface. Data storage and remote control requirements can be achieved by the communications interface.
