GW Instek 70MHz Spectrum Analyzer 2-channel, DSO, power supply MDO-2072EX

Product Highlights The GW Instek MDO-2072EX is an amazing combination instrument: it’s a mixed-domain 2-channel 70MHz oscilloscope that includes a built-in spectrum analyzer (not just an FFT calculation) to display the frequency domain, as well as a 2-channel arbitrary waveform generator, a 5,000 count DMM, and a 5V/1A power supply. The first of its kind, MDO-2000EX is the only oscilloscope to provide a space-saving combination of all these instruments, making it ideal for educational or space-restricted use. The MDO-2000EX Series is available in three bandwidths: 70, 100 and 200MHz and in 2 or 4 channel models. A conventional digital oscilloscope uses FFT calculations over the entire signal bandwidth up to half the sampling rate. But inadequate calculation capability means it is impossible to have a signal's detailed frequency information due to the insufficient frequency resolution from the calculation. In contrast, the MDO-2000E series analyzes just a defined signal spectrum of interest to allow engineers to effectively conduct precision signal measurements in the frequency domain. Users can input specific data of interest regarding the signal: center frequency, span, start/stop frequency similar to a traditional spectrum analyzer. While observing 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 oscilloscope' FFT, MDO-2000E series allows engineers to effectively conduct signal measurements both in the time and frequency domains. The MDO-2000E series frequency domain also includes Spectrum Trace Type settings (Normal, Max-hold, Min-hold, and Average). Users can select various Spectrum Traces for simultaneous display. Detection method (Sample, +Peak, -Peak, and Average) can be individually set for each trace. Offering an advantage over conventional spectrum analyzers, the spectrum function of MDO-2000E series can test signals that are below 9kHz, such as audio and vibration signals. The MDO-2000E series can also test signals that have a DC component without damaging the instrument. The MDO-2000E series offers the same capabilities as real-time spectrum analyzers, but faster than frequency sweeping. This is because the MDO-2000E series utilizes advanced digital circuitry and software to render the frequency display. Ordinary spectrum analyzers process narrow frequency bandwidths which are frequency swept over time. Thousands of frequency sweeps are collected to form a spectrum. The FFT settings of ordinary digital oscilloscopes are dependent on the horizontal scale or sample rate setting, which is totally different from the frequency range setting of the MDO-2000E series. Most DSOs will have insufficient frequency resolution. 70MHz bandwidth 2 channels Real time sample rate for each channel is 1GSa/s Per Channel 10M memory depth and VPO waveform display technology Waveform update rate up to 120,000 wfms/s 8 “ WVGA TFT LCD display Maximum 1M FFT provides higher frequency domain resolution measurements High, low and band pass filter functions 29,000 segmented memories and waveform search functions I2C/SPI/UART/CAN/LIN serial bus trigger and decoding function Data log function is able to track signal changes up to 1000 hours Network storage function Mask test function MDO-2000EX includes a spectrum analyzer, a dual channel 25MHz AWG, DMM and power supply Each Unit Includes: Quick Start Guide User Manual CD Power Cord GTL-110 BNC-BNC Cable (x2) GTL-105A Alligator Clip test lead GTL-207 Banana plug test lead GTP-070B-4 70MHz (10:1/1:1) Switchable passive probe (one per channel)
