The Instek GDS-3652A Digital Storage Oscilloscope has 650 MHz bandwith and features two analog channels with an option for 16-channel logic analysis. Moreover, it features a per-channel memory length of up to 200 Mpts, as well as sampling rates of 5 GSa/s (1 ch) and 2.5 GSa/s (2 ch).

Dual Domain Measurement

For frequency domain measurement, the GDS-3652A is equipped with a dual-channel spectrum analyzer, enabling users to measure and analyze the frequency domain signals of two channels at the same time.

It is also equipped with a Spectrogram function, which enables users to easily observe complex frequency domain fluctuations. These are proportionally decomposed into simple superimposed waves so as to understand the signal strength distribution. The soft keys allow users to have more intuitive settings for operation, which can improve measurement efficiency.

25 MHz dual channel arbitrary waveform generation

A 25MHz dual-channel arbitrary waveform generator is included as standard with the GDS-3652A. 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.

13 Sets of Switching Mode Power Supply Measurements (option GDS-DS3A-PWR)

The GDS-3652A 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.

16-channel logic analysis (option GDS-DS3A-16LA)

The GDS-3652A can be upgraded to a mixed-signal oscilloscope (MSO) by selecting an optional 16-channel logic analyzer, which is a plugin. When a user has several GDS-3652As, they can plug in an optional logic analyzer to other units at any time without installing any software. Users can analyze digital signals, I2C, SPI, UART, CAN, LIN, and parallel buses.
