Compact models have a built-in true spectrum analyzer,
dual channel 25MHz AWG, DMM, and a power supply to suit educational and restricted space situations
Fairport, NY, USA -- Saelig Company, Inc., has introduced
the GW Instek MDO-2000E
Series Oscilloscopes which combine several test instruments in one enclosure. An actual
spectrum analyzer is included in the design, not just an FFT calculation to display the frequency
domain. The series includes two instrument combinations: MDO-2000EG and MDO-2000EX. MDO-2000EG
models have a built-in true spectrum analyzer and a dual channel 25 MHz arbitrary waveform
generator, while the MDO-2000EX models feature a built-in a true spectrum analyzer, an 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 spectrum analyzer, DMM and
power supply, making it ideal for educational or space-restricted use. The MDO-2000E Series
is available in three bandwidths: 70, 100 and 200 MHz 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, and start/stop frequency, similar to a traditional spectrum analyzer. While observing
frequency domain display, engineers can observe waveform characteristics which are not easily
seen from time domain waveforms, such as the harmonic composition of a waveform and the frequency
characteristics of a modulation signal. Compared with an oscilloscope's FFT, the MDO-2000E
series allows engineers to effectively conduct signal measurements both in the time and frequency
Offering an advantage over conventional spectrum analyzers, the spectrum function of MDO-2000E
series can test signals that are below 9 kHz, 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.

series are available now from Saelig Company Inc. For detailed specifications, free technical
