The MDO4000C, with its integrated oscilloscope, logic analyzer, and
spectrum analyzer is the ultimate tool for debugging modern EMI issues.
Many EMI problems are caused from events rooted in the time domain,
such as clocks, power supplies, and serial data links. With its ability to
provide time correlated views of analog, digital, and RF signals, the
MDO4000C is the only instrument available that can discover the
connection between time-domain events and offending spectral emissions.
RF probing – Signal input methods on spectrum analyzers are typically
limited to cabled connections or antennas. But with the optional TPA-N-VPI
adapter, any active, 50 Ω TekVPI probe can be used with the spectrum
analyzer on the MDO4000C Series. This enables additional flexibility when
hunting for noise sources and enables easier spectral analysis by using
true signal browsing on an RF input.
In addition, an optional preamplifier accessory assists in the investigation of
lower-amplitude signals. The TPA-N-PRE preamplifier provides 12 dB
nominal gain across the 9 kHz - 6 GHz frequency range.
The optional TPA-N-VPI adapter enables any active, 50 Ω TekVPI probe to be
connected to the RF input.
Visualizing changes in your RF signal – The time domain graticule on
the MDO4000C Series display provides support for three RF time domain
traces that are derived from the underlying I and Q data of the spectrum
analyzer input including:
Amplitude - The instantaneous amplitude of the spectrum analyzer
input vs. time
Frequency - The instantaneous frequency of the spectrum analyzer
input, relative to the center frequency vs. time
Phase - The instantaneous phase of the spectrum analyzer input,
relative to the center frequency vs. time
Each of these traces may be turned on and off independently, and all three
may be displayed simultaneously. RF time domain traces make it easy to
understand what's happening with a time-varying RF signal.
The orange waveform in the Time Domain view is the frequency vs. time trace derived
from the spectrum analyzer input signal. Notice that Spectrum Time is positioned during
a transition from the highest frequency to the lowest frequency, so the energy is spread
across a number of frequencies. With the frequency vs. time trace, you can easily see
the different frequency hops, simplifying characterization of how the device switches
between frequencies.
Advanced RF analysis – When paired with SignalVu-PC and its Live Link
option, the MDO4000C Series becomes the industry's widest bandwidth
Vector Signal Analyzer with up to 1 GHz capture bandwidth. Whether your
design validation needs include Wireless LAN, wideband radar, high data
rate satellite links, or frequency-hopping communications, SignalVu-PC
vector signal analysis software can speed your time-to-insight by showing
you the time-variant behavior of these wideband signals. Available analysis
options include Wi- Fi (IEEE 802.11 a/b/g/j/n/p/ac) signal quality analysis,
Bluetooth Tx compliance, pulse analysis, audio measurements, AM/FM/PM
modulation analysis, general purpose digital modulation and more.
MDO4000C paired with SignalVu-PC to analyze 802.11ac modulation.
Time synchronized insights into Analog, Digital, and RF – The
MDO4000C Series is the world's first oscilloscope with a built in spectrum
analyzer. This integration enables you to continue to use your debug tool of
choice, the oscilloscope, to investigate frequency domain issues rather than
having to find and re-learn a spectrum analyzer.
