4-Channel 200 MHz Bandwidths
The GDS-2004E digital oscilloscope features bandwidth 200 MHz. The two-channel models provide 1 GSa/s real-time sampling rate for each channel; while the four-channel models provide 1 GSa/s maximum real-time sampling rate. All models are equipped with waveform update rate of 120,000 wfm/s.

Fast Retrieval, Precision Measurement
The GDS-2004E has 10 Mega point record length in each channel with Waveform Search and Segmented Memory functions, which greatly enhance the value of long memory utilization of these DSOs. The 8-inch 800 x 480 TFT LCD display and the minimum 1mV/div vertical range allow the GDS-2004E series to measure complex feeble signals and clearly display complex and random waveforms.

Low Background Noise
For small signal measurement, oscilloscope's background noise will affect the measurement results. The GDS-2004E low noise amplifying circuit can tremendously improve overall noise interference to produce the genuine signal demonstration.

GDS-2004E oscilloscopes feature adjustable backlight intensity.

GDS-2004E Digital Storage Oscilloscopes

120,000wfm/s Waveform Update Rate
The GDS-2004E digital oscilloscope allows you to easily observe rare transient waveforms and jitters with the high waveform update rate of 120,000 wfm/s. The advanced VPO (Visual Persistence Oscilloscope) signal processing technology combines the multi-layered gray display to enhance waveform display efficiency that allows you to easily and completely observe inrush signals and rare transient waveforms to increase waveform debugging efficiency.

1M FFT Display
The FFT (Fast Fourier Transform) function of the GDS-2004E Series provides the maximum 1M points display. The function supports four window displays, including Rectangular, Hamming, Hanning, and Black-harris, allowing you to select window display for frequency domain analysis according to your test requirements. The GDS-2004E series not only provides the FFT function but also FFTrms, vertical adjustment, and local zoom-in functions. Via rapid waveform update rate and waveform search functions, you can precisely observe the test results of frequency domain.

Support I2C/SPI/UART/CAN/LIN Decoding and Analysis
The serial bus technology has been widely applied in the present embedded application design. The GDS-2004E series provides serial bus analysis function and 10M long memory depth to trigger, decode, and analyze, in a long period, frequently used I2C, SPI and UART serial bus and CAN/LIN bus, which is often used by automotive communications.

The GDS-2000E series shares many rich functionalities with the GDS-2000A series — including Zoom Window, Play/Pause, 36 automatic measurements with statistics mode, and remote software and digital voltage meter.

The GDS-2000E Series' applications include educational training and laboratory, Q/A testing, serial bus design and debugging, and maintenance services.
