Datasheet
Spectrogram display illustrates slowly moving RF phenomena. As shown here, a signal
that has multiple peaks is being monitored. As the peaks change in both frequency and
amplitude over time, the changes are easily seen in the Spectrogram display.
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.
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
correlated 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.
Spectrum traces
The MDO4000B 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.
Ultra-wide capture bandwidth
Today's wireless communications vary significantly with time, using
sophisticated digital modulation schemes and, often, transmission
techniques that involve bursting the output. These modulation schemes can
have very wide bandwidth as well. Traditional swept or stepped spectrum
analyzers are ill equipped to view these types of signals as they are only
able to look at a small portion of the spectrum at any one time.
The amount of spectrum acquired in one acquisition is called the capture
bandwidth. Traditional spectrum analyzers sweep or step the capture
bandwidth through the desired span to build the requested image. As a
result, while the spectrum analyzer is acquiring one portion of the spectrum,
the event you care about may be happening in another portion of the
spectrum. Most spectrum analyzers on the market today have 10 MHz
capture bandwidths, sometimes with expensive options to extend that to
20, 40, or even 160 MHz in some cases.
In order to address the bandwidth requirements of modern RF, the
MDO4000B Series provides ≥1 GHz of capture bandwidth. At span settings
of 1 GHz and below, there is no requirement to sweep the display. The
spectrum is generated from a single acquisition, thus guaranteeing you'll
see the events you're looking for in the frequency domain.
