• 2 analog channels / 350 MHz bandwidth

• 16 digital channels (requires option GDS-DS3A-16LA)
• Dual channel spectrum analyzer (DC-2.5 GHz) with spectrogram
• Dual channel 25 MHz arbitrary waveform generator
• 13 power analysis measurements (requires option GDS-DS3A-PWR)

The Instek GDS-3000A is available in two bandwidths (350 and 650 MHz), with two or four analog channels and an option for 16 channel logic analysis. The GDS-3000A features a per-channel memory length of up to 200 Mpts, as well as sampling rates up to 5 GSa/s.

Each of these models also includes a dual channel, 25 MHz arbitrary waveform generator, and a dual channel spectrum analyzer (DC-2.5 GHz) with spectrogram.

The GDS-3000A can be upgraded to a mixed-signal oscilloscope (MSO) with an optional 16-channel, plug-in logic analyzer. When you have several GDS-3000As, you can plug in an optional logic analyzer to other unit at any time without installing any software.

Users can analyze digital signals, I2C, SPI, UART, CAN, LIN and parallel bus.

For frequency domain measurement, a dual channel spectrum analyzer (DC - 2.5 GHz) is built in. Users can measure and analyze dual channel frequency domain signals at the same time. It also includes the Spectrogram function, which allows users to easily observe the signal's strength distribution and the relationship of the spectrum distribution over time. In addition, the dual Spectrum Analyzer and Spectrogram can test the frequency response of the left and right channels of the Audio Amplifier at the same time.

A 25MHz dual-channel arbitrary waveform generator is included as standard with the GDS-3000A. Waveform shapes include Sine, Square, Pulse, Ramp, DC, Noise, Sinc, Gaston, Lorentz, Exponential Rise, Exponential Fall, Haversine, Cardiac and more.

Users can select the arbitrary waveform function to store the signal measured by the analog channel or directly output it from the signal generator.

This function allows users to conveniently generate various types of measured signals to simulate diversified signal outputs. The frequency response analysis function (Bode Plot) is also equipped, 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.

The GDS-3000A offers an optional software package for switch mode power supply testing. The provided power supply test items include:

• AC input analysis items: Power Quality, Harmonics, Inrush Current
• DC output analysis required test items: Ripple/Noise, Transient Response Analysis, Turn On/OFF, Efficiency
• Control Loop response (Bode), and PSRR (Power Supply Rejection Ratio)
• Complete switching component analysis items: Modulation, Switching loss, SOA (Safe Operation Area), and Magnetics analysis: B-H curve.

On the oscilloscope’s side, a power supply for 50MHz (GCP-530) and 100MHz(GCP-1030) current probes is provided. This feature can save users the cost of purchasing power supplies for current probes, as well as relieving the burden of carrying the power supply when traveling.
