The GDS-3000A series oscilloscope offers a recording length of up to 200Mpts per channel, and the advantage of an ultra long recording length allows users to maintain a high sampling rate even under low-speed time settings. When the sampling rate is twice as high as the testing frequency, it can ensure that the captured signal is not distorted, which is beneficial for observing signal changes for a long time at low speeds, which is very helpful for in-depth analysis of the signal.

Regarding waveform update rate, GDS-3000A can reach up to 200000

wfm/s， Users can easily observe sporadic abnormal signals. Segmented memory can continuously capture up to 490000 segments and can be used in conjunction with trigger condition settings to skip long periods of unchanged waveforms and only record meaningful waveforms, providing the most effective memory usage method. Segmented memory also provides masking function, allowing users to quickly determine whether a large number of signals exceed the target range, and can quickly search for the time and actual signal of erroneous waveforms.

In terms of measurement functionality, 38 measurement items are provided. The fine scale function allows users to fine tune the vertical scale as needed to achieve full-size measurement and improve the accuracy of voltage or current measurement. Provided a high-resolution mode acquisition method, effectively eliminating noise and improving the accuracy of automatic measurement. A dynamic vertical scale display is provided on the right side of the screen monitor, making it easier for users to interpret the vertical amplitude corresponding to the measurement signal. Standard 1

The selection of M Ω and 50 Ω input impedances allows users to choose input impedances according to different measurement requirements to achieve impedance matching. The search function can quickly find qualified signals based on user settings, which is very helpful for searching and comparing sporadic waveforms.

The cursor marking function allows users to clearly observe the voltage (or current), time, and incremental data between the points measured by the cursor. By using the indicator function, the measurement range can be displayed by showing the waveform section.

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

GDS-3000A provides a wide range of testing items for switch mode power supply testing. The provided power testing items include AC input analysis items: power quality, Norwave, surge current; Test items required for DC output analysis: ripple/noise, transient response analysis, on/off analysis, efficiency; Control loop response (Bode) and power supply rejection ratio (PSRR); Complete analysis of switch components: modulation, switch losses, SOA (safe working area), and magnetic analysis: B-H curve. GDS 3000A has a built-in power supply for 50MHz (GCP-530) and 100MHz (GCP-1030) current probes. This feature can save users the cost of purchasing current probe power supplies and reduce the burden of carrying current probe power supplies when going out.

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