The GW Instek GW-MDO-2000E Series is multi-functional Mixed Domain Oscilloscope. The series includes two feature combinations: GW-MDO-2000EG models have a built-in spectrum analyzer and a dual channel 25MHz arbitrary waveform generator (3 functions), whereas the GW-MDO-2000EX models feature a built-in a spectrum analyzer, arbitrary waveform generator, and also a 5,000 count DMM, and a 5V/1A power supply (5 functions). The first of its kind, the GW-MDO-2000EX is the only oscilloscope to be equipped with a DMM and a power supply in the T&M industry. While entering the spectrum mode, the GW-MDO-2072EX will display a full screen of frequency domain. Users can input Center frequency, Span, Start frequency, and Stop frequency based upon test requirements so as to rapidly and intuitively observe the required frequency range that allows users to experience the user interface of a traditional spectrum analyzer. While observing the frequency domain display, engineers can observe waveform characteristics, which are not easily to be seen from time domain waveforms, for instance, the harmonic composition of a waveform and the frequency characteristics of a modulation signal. Compared with the FFT of a normal oscilloscope, this Mixed Domain Oscilloscope allows engineers to effectively conduct signal measurements on frequency domain.

Conventional DSO's FFT always calculates the entire signal bandwidth up to half the sampling rate (Fs). However, the insufficient calculation capability can't conduct an FFT calculation with more points. Users can't observe the signal's detailed frequency information due to the insufficient frequency resolution from the calculated result. However, the GW Instek GW-MDO-2072EX analyzes the signal spectrum of interest. Compared with an oscilloscope's FFT, the GW-MDO-2072EX allows engineers to effectively conduct signal measurements on frequency domain. The MDO frequency domain also includes Spectrum Trace Type settings (Normal, Max-hold, Min-hold, and Average). Users can freely select various Spectrum Traces for simultaneous display. The Detection method (Sample, +Peak, -Peak, and Average) can be individually set for each Trace. Additionally, users, via the Cursor, can manually mark the corresponding positions to reflect Frequency and Amplitude. The Search function can also be applied to log spectrum's Peak Table. Amplitude is displayed with dB and Marker can obtain measurement data. Users can use the Search function to search and mark the amplitude and frequency of spectrum signal. Search methods include Max. peak and threshold. Measurement results can be displayed and saved.

Compared with the general spectrum analyzers, the spectrum function of the GW Instek GW-MDO-2072EX can test below~9kHz signals, which is applicable to the frequency domain analysis of audio frequency and vibration. The Oscilloscope can also test the frequency domain signal with a DC component without damaging the instrument. With respect to frequency domain waveform display, the GW-MDO-2072EX, features the same capability as a real-time spectrum analyzer, and is faster than a general spectrum analyzer. The reason is because it utilizes digital circuitry and software to calculate the FFT. A general spectrum analyzer can only process the signal of a narrow frequency bandwidth at a time by frequency sweeping. Each sweep will take from several ms up to dozens of ms. Hundreds and thousands of frequency sweeps are gathered to form a spectrum. Therefore, the displayed spectrum is not obtained at the same time. The GW-MDO-2072EX however obtains the full spectrum display at the same time and is faster than the frequency sweeping method. The FFT settings of an oscilloscopes are based upon horizontal scale (sample rate) setting, which is totally different from the frequency range setting of the Mixed Domain Oscilloscope. Most instruments will have insufficient frequency resolution due to insufficient FFT points while conducting spectrum measurement by FFT. Compared with the FFT of oscilloscopes, the GW-MDO-2072EX provides users with signal measurement requirements of less than 9kHz, plus a better setting interface, measurement resolution and faster measurement speed.

In addition to the new functionalities, the hardware characteristics of GW Instek GW-MDO-2000E are identical to those of the GW-GDS-2000E Series. Both the GW-MDO-2000EG and GW-MDO-2000EX Series are equipped with an 8-inch display, and feature bandwidth selections of 200MHz, 100MHz, and 70MHz. Models with two analog channels provide 1GSa/s real-time sampling rate per channel; models with four analog channels provide 1GSa/s maximum real-time sampling rate. The waveform update rate of 120,000 wfm/s and the minimum 1mV/div vertical range allow the GW-MDO-2072EX to measure complex small signals and clearly display measurement results. With respect to the memory depth, this Mixed Domain Oscilloscope provides 10M long memory for users to completely retrieve and analyze waveforms. Users, based upon the application requirements, can select 1k, 10k, 100k, 1M or 10M memory depth. The segmented memory can be divided into a maximum of 29,000 sections for users to bypass any unimportant waveforms so as to swiftly search all of the required waveforms. With the function, more meaningful waveforms can be saved and target waveforms can be displayed rapidly. With the waveform search function, users can quickly search desired waveforms according to the required trigger conditions. The GW-MDO-2072EX also provides 1M FFT display that allows users to correctly and efficiently acquire measurement results of the frequency domain. Enhanced by the high waveform update rate of 120,000wfm/sec, the Window Zoom and the Peak Search functions, these units are the optium choice for an economical and multi-function mixed domain oscilloscope.
