GDS-3000A Digital Storage Oscilloscope

GDS-3000A series oscilloscopes offer record lengths of up to 200Mpts per channel. The advantage of the extra-long record length allows users to maintain a high sampling rate even at low-speed time settings. When the sampling rate is two times higher than the test frequency, it ensures that the captured signals are free of distortion, which facilitates the observation of signal variations for a long period of time at low speeds, which is very helpful for in-depth analysis of signals.

Regarding the waveform update rate, the GDS-3000A reaches up to 200,000 wfm/s, allowing users to easily observe sporadic abnormal signals. The segmented memory, which can continuously capture up to 490,000 segments, can be used in conjunction with trigger condition settings to skip waveforms that have remained unchanged for a long period of time and record only meaningful waveforms, thus providing the most efficient use of memory. A mask function is also provided under the segmented memory, allowing the user to quickly determine if a large number of signals are out of the target range, and to quickly search for the time of the erroneous waveform and the actual signal.

In terms of measurement functions, 38 measurement items are provided. The Fine Scale function allows users to fine-tune the vertical scale as needed to achieve full-size measurements and improve the accuracy of voltage or current measurements. A high-resolution mode acquisition method is provided, effectively eliminating noise and improving the accuracy of automatic measurements. A dynamic vertical scale display is provided on the right side of the on-screen monitor, making it easier for users to interpret the vertical amplitude corresponding to the measured signal.

Standard 1 MΩ and 50Ω input impedance selections allow the user to select the input impedance for impedance matching based on different measurement requirements. The search function allows quick finding of qualified signals based on user settings, which is helpful for finding and comparing sporadic waveforms.

The cursor marking function allows the user to clearly observe the voltage (or current), time and incremental data between the points measured by the cursor. Using the indicator function, the measurement range can be shown by displaying a portion of the waveform.

For frequency domain measurement, GDS-3000A provides FFT measurement function and dual-channel spectrum analyzer. Users can measure and analyze dual-channel frequency domain signals simultaneously. The spectrogram function allows users to easily observe the spectral distribution over time in order to observe the spectral characteristics of the signal.

GDS-3000A provides rich test items for switching power supply testing. Power supply test items provided include AC input analysis items: power quality, Noise, inrush current; DC output analysis required test items: ripple/noise, transient response analysis, on/off analysis, efficiency; control loop response (Bode) and power supply rejection ratio (PSRR); complete switching component analysis items: modulation, switching loss, SOA (Safe Operating Area) and magnetic analysis: B - H curve. The GDS-3000A has built-in power supplies for 50MHz (GCP-530) and 100MHz (GCP-1030) current probes. This feature saves users the cost of purchasing current probe power supplies and reduces the burden of carrying current probe power supplies on the go.

The GDS-3000A comes standard with a dual channel 25MHz arbitrary wave generator. Users can select the arbitrary wave function to store signals measured by analog channels or output them directly from the generator. This function allows users to conveniently generate various types of measurement signals to simulate various signal outputs. It is also equipped with a frequency response analysis function (Bode Plot), which can be applied to product circuit and component characterization verification and analysis, including RLC circuit design, filter design and amplifier design verification and analysis.

The GDS-3000A provides a wealth of communication interfaces. In addition to the commonly used USB Host, USB device port and LAN port, it includes a highly stable RS232 interface and an optional GPIB interface.
