What is the single feature lacking from most digital storage oscilloscopes? Adequate memory depth. Is the memory depth of your DSO large enough?
With 2M points of memory, the GDS-1000A-U has the capability to acquire far more waveform data compared to other DSOs in the same performance range.
The 1GSa/s sampling rate and 2M point memory plays an extremely powerful role for single-shot waveform capture. Properly set the trigger conditions to baby-sit the expected waveform. When the single-shot waveform is triggered and captured, you are able to check and see the single-shot event without losing any detailed information. A DSO, with high sampling rate but short memory, can't do the job of single-shot waveform capture as good as what GDS-1000A-U can do.
EASY TO USE
Full-featured acquisition mode and 27 auto measurement functions help users to measure the parameters of captured waveforms accuray. The advanced Auto-Set function enables GDS-1000A Series to catch waveform automatically and display waveform quickly. With Arithmetic functions, +, -, x and FFT, GDS-1000A-U Series keep users being aware of the measurement results by updating values immediay. Without almost extra calculation, GDS-1000A-U can provide sufficient information of testing.
CONVENIENT TOOLS FOR WAVEFORM OBSERVATION-DELAY ON/ OFF
For the convenience of waveform observation and analysis, the GDS-1000A-U includes Delay On/Off functions usually seen only in the higher end products. With Delay On, a signal can be observed from an offset of the trigger point. With this feature, the horizontal scale, so as the waveform scale, can be expanded and centered on the delay point, but not the trigger point. This allows a signal to be observed in detail where needed.
CONVENIENT TOOLS FOR WAVEFORM 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 may become degraded, which must 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.
FFT & FFTrms
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 a decibel （dB）.
However using dB, it is difficult to identify the fundamental frequency of a signal from a noisy spectrum sometimes. With the FFTrms function, the GDS-1000A series can clearly display the fundamental frequency of an acquired waveform.
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 GDS-1000A-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 incomp rehensible command line syntax. With the simple user interface and robust features, FreeWave allows you to get the most out of the GDS-1000A with little effort. When a test report is needed you no longer have to copy and paste data into your documents. With the Microsoft Excel or Word Add-ins, you only need to click the Add-in icon to import your test data, saving you time and effort.
