Datasheet
Spectral display of a bursted communication both into a device through Zigbee at
900 MHz and out of the device through Bluetooth at 2.4 GHz, captured with a single
acquisition.
Spectrum traces – The MDO4000C Series spectrum analyzer offers four
different traces or views including Normal, Average, Max Hold, and Min
Hold. You can set the detection method used for each trace type
independently or you can leave the oscilloscope in the default Auto mode
that sets the detection type optimally for the current configuration. Detection
types include +Peak, - Peak, Average, and Sample.

Triggered versus Free Run operation – When both the time and
frequency domains are displayed, the spectrum shown is always triggered
by the system trigger event and is time-synchronized with the active time-
domain traces. However, when only the frequency domain is displayed, the
spectrum analyzer can be set to Free Run. This is useful when the
frequency domain data is continuous and unrelated to events occurring in
the time domain.
Advanced triggering with analog, digital and spectrum analyzer
channels – In order to deal with the time-varying nature of modern RF
applications, the MDO4000C Series provides a triggered acquisition system
that is fully integrated with the analog, digital and spectrum analyzer
channels. This means that a single trigger event coordinates acquisition
across all channels, allowing you to capture a spectrum at the precise point
in time where an interesting time domain event is occurring. A
comprehensive set of time domain triggers are available, including Edge,
Sequence, Pulse Width, Timeout, Runt, Logic, Setup/Hold Violation, Rise/
Fall Time, Video, and a variety of parallel and serial bus packet triggers. In
addition, you can trigger on the power level of the spectrum analyzer input.
For example, you can trigger on your RF transmitter turning on or off.
The optional MDO4TRIG application module provides advanced RF
triggering. This module enables the RF power level on the spectrum
analyzer to be used as a source for Sequence, Pulse Width, Timeout, Runt,
and Logic trigger types. For example, you can trigger on a RF pulse of a
specific length or use the spectrum analyzer channel as an input to a logic
trigger, enabling the oscilloscope to trigger only when the RF is on while
other signals are active.
RF measurements – The MDO4000C Series includes three automated
RF measurements - Channel Power, Adjacent Channel Power Ratio, and
Occupied Bandwidth. When one of these RF measurements is activated,
the oscilloscope automatically turns on the Average spectrum trace and
sets the detection method to Average for optimal measurement results.

EMI troubleshooting – EMC testing is expensive regardless of whether
you purchase the equipment to perform in-house testing or you pay an
external test facility to certify your product. And that assumes that your
product passes the first time. Multiple visits to a test house can add
significant cost and delay to your project. The key to minimizing this
expense is early identification and debug of EMI issues. Traditionally,
spectrum analyzers with near field probe sets have been used to identify
the location and amplitude of offending frequencies, but their ability to
determine the cause of the issue is very limited. Designers are increasingly
using oscilloscopes and logic analyzers as EMI issues become more
transient due to the complex interactions of numerous digital circuits in
modern designs.
