About MemoryPrime Technology
With the increasing complexity of signals, traditional digital storage oscilloscopes don't have the capability of displaying an input signal completely, or comparing the relative relationship between signals accurately due to memory constraints. After all, the waveform record length and the sample rate of a DSO are tied to memory depth, and only the combination of a high sample rate and a long record length can make detailed waveform analysis possible. Assuming a constant sample rate, the more memory a DSO has, the longer the signal can he displayed. Conversely, assuming a limited memory depth, a signal will be observed for a shorter time with a faster sample rate. In order to fully utilize the advantage of 2M points of memory without sacrificing the waveform update rate, the GDS-1152A-U adopts Memory Prime technology. Memory Prime uses a high speed signal processor in parallel with a CPU to increase the waveform reconstruction speed. Listing a high Speed signal processor and 2M points of memory, the GDS-1152A-U is able to run at the maximum sampling speed of 1GSa/s under a wide range of time base selections (100us/div - 25ns/div). This unparalleled performance creates a significant differentiation compared to all other economic DSO products available in the market today.
The sample rate of a DSO is closely related to memory size. Shallow memory digital storage oscilloscopes compromise the sample rate over a larger time base range as there is not enough memory to display the signal on the screen at the maximum sample rate. For example, a digital storage oscilloscope with a sample rate of 1GSa and a 2.5k point memory length can operate with a horizontal sweep speed below 20ns/div, but only by reducing the sampling rate accordingly. When the sample rate is reduced, there is a greater possibility that critical details get omitted. However with a larger memory depth, a high sampling rate can be maintained over a wider horizontal range. The GDS-1152A-U is able to maintain a sampling rate of 1Ga/S over 12 horizontal ranges, superior to that of other oscilloscopes with a 2.5k memory depth. Utilizing a greater memory depth, the GDS-1152A-U allows you to design and debug your projects more effectively.

Ease of Use
Full-featured acquisition mode and 27 auto measurement functions help users to measure the parameters of captured waveforms accurately. The advanced Auto-Set function enables the GDS-1000A-U Series to catch waveforms automatically and display waveforms quickly.
With Arithmetic functions, +, -, x, FFT, FFTrms and Zoom FFT. GDS1152AU keeps users aware of the measurement results by updating values immediately. Without almost extra calculation, GDS-1152A-U can provide sufficient information of testing.
FFT/ FFTrms/ ZOOM FFT Measurement
Zoom FFT Measurement
To observe the fundamental and harmonic components of a signal, the FFT math function on a digital storage oscilloscope is often used. Typically, the traditional unit of the FFT is the decibel [dB]. However, when using dB it is sometimes difficult to identify the fundamental frequency of a signal from a noisy spectrum. With the FFTrms function, the GDS-1152A-U can clearly display the fundamental frequency of an acquired waveform. Zoom FFT provides users with observation flexibility that they can move FFT waveform horizontally and zoom in it up to 20X to investigate details of FFT signal.
For the convenience of waveform observation and analysis, the GDS1152AU includes Delay On/Off functions usually available only in the higher end products. With Delay On, a signal can be observed from an offset of the trigger point. This feature allows the horizontal scale and the waveform scale to be expanded and centered on the delay point rather than the trigger point, allowing a signal to be observed in detail where needed.
Observation-Expand by Ground/Center
In a DSO, "AC Coupling" is normally used to isolate the AC components of a signal by blocking the DC components. This is useful to see a signal with a small AC component that is offset with a large DC voltage. With AC coupling to block the DC voltage, small AC waveforms can be observed from the center of the screen for measurement or examination. However, capacitive loading under AC coupling mode may cause waveform distortion as low frequency components become degraded, an effect that needs to be avoided in frequency critical applications. The Expand by Ground and Center functions are convenient tools to expand a waveform vertically. With this feature, the vertical scale of a waveform can be expanded either from the ground reference or from the center of the screen without causing capacitive loading.
PC Remote Control Software
Using a USB port coupled with FreeWave remote monitoring software is the easiest and most convenient way to capture data from the GDS1152A-U. With FreeWave, a screenshot can be saved as an image file (.bmp/.jpg), waveform data(.csv) can be logged, and movie files(.wmv) can be recorded in real-time. Not only can FreeWave monitor and record waveforms over a long period of time, but previously recorded waveforms can also be observed. Instrument settings can even be configured without the need to learn incomprehensible command line syntax. With the simple user interface and robust features, FreeWave allows you to get the most out of the GDS1152A-U with little effort.
USB Host & Data Logger
USB host function enables the user to store waveform settings, data or images on a USB flash disk. Furthermore, the data logger can continue monitoring input signals and storing their waveform data in the USB flash disk when trigger conditions are met, saving the users' effort to tracking signals manually and allowing them to analyze and observe waveform data afterwards.
Go/NoGo testing function allows the user to check whether the incoming signal violates the user-defined template for examining waveforms. Users can easily define this template by setting the tolerance ratio to determine violation conditions. The function can freely adjust the size of template. A defect message will be shown if the DUT’s waveform is abnormal and touches the template. The function is not only a very useful measurement tool for production lines but also a very convenient tool for engineers to observe waveforms in a long period of time.
