Prominent Signal Measuring Capability

Observation of the signal more clearly

DSO-3000 Series has a 5.6-inch 320x234 TFT LCD color display for watching signals from any viewing angle. Different from traditional oscilloscope’s fixed menu display, DSO-3000 series can display the waveform to full screen according to your need.

Single MENU ON/OFF key enables you to view more information in 25% more display area.

Deep memory depth for capturing more

Maximum 2.4Mpts memory depth for each channel on all models, DSO-3000 series is easy to record and analyze the waveform. Even under the slow time base settings, you can maintain a high sampling rate. This allows you observe the signal in more details. In a given sampling rate, the more sampling points mean the longer the time observed.

Delayed sweep mode for both details and the whole waveform

In Delayed sweep mode, you can view simultaneously the details on a particular part and the whole waveform. Through split display you can zoom in on a particular area on your signal while still viewing the entire captured waveform.

Powerful Functions
 
DSO-3000 series oscilloscope is your indispensable assistant to get your job done easier and faster.


Auto scale

Auto scale can evaluate all input signals and set the correct condition to best display the signals. Single period or multi periods can be selected to display in the current display window.


Running control

RUN/STOP mode:
To continuously observe waveform or freeze the current waveform on the screen.

SINGLE mode:
To automatically recognize signal meeting trigger conditions,and to immediately sample the signal to fixedly display,especially suitable to sample single signal.


Math Function and FFT

DSO-3000 series provides some important math operations, including addition, subtraction, multiplication, or 1024-point FFT (Fast Fourier Transforms). For time-domain signal analysis, you can use additions (signal superimpose), subtraction (elimination of noisy component or differential operation, etc.), multiplication (frequency mixing, etc.) processes.

For frequency-domain analysis, you have FFT (Fast Fourier Transforms) with five window function (Rectangular, Hanning, Hamming, Blackman, Flat-Top). And spectrum amplitudes of FFT can be displayed in linear or dBV (RMS) scale type.

24 Automatic Parametric Measurements

DSO-3000 series provides up to 24 automatic parametric measurements. You can either install three commonly used screen measurements or display all the 24 measurements of the current selected source on the screen. Auto measurement can not only save your time for eye observation, but also provide you more accurate results. Without complicated operation, you can get your measurement results easily and quickly.

Convenient observation of all signals

Roll mode: 
It is one of the useful features of DSO-3000 series to test low-speed signal accurately. Using the Roll mode, the change of ultra slow speed signal can be observed.

X-Y mode:
In X-Y mode, channel 1 becomes the X input and channel 2 becomes the Y input. Lissajou’s figure can be displayed to calculate phase difference of same-frequency signals.

Video Trigger:
DSO-3000 series can synchronously trigger on specified line or field of the standard NTSC or PAL/SECAM video signal.

More Functions

Digital Filter

DSO-3000 series provides several digital filters, including low pass, high pass, band pass, and band reject filters. It can be applied to displayed signals to acquire expected results, such as to simulate the effect of a hardware filter, to reject aliasing noise or error signal to clearly observe a signal of interest, etc. The high and low cut-off frequency can be set randomly.

Waveform Record and Replay

DSO-3000 series can record the input signal over a period of time continuously in the internal or external memory for future analysis. Up to 1000 frames can be recorded with the variable time interval ranging from 1 ms to 1000s. The recorded frames can be played back continuously or played frame by frame, so that you can observe any frame and capture any tiny abnormality.


PASS/FAIL Judgment

On the production line, it is valuable to judge some kind of signal and decide if it is good or not. DSO-3000 series can measure the selected input signal and compare it with the predefined PASS/FAIL regulations and then output the PASS/FAIL result. This function is more convenient and quick and reduces error os man-made judgement.

Auto Calibration

DSO-3000 can automatically calibrate its vertical, horizontal and trigger system, so that it can work with the best measurement accuracy.
