The MSO-9212 has time synchronized oscilloscope and logic analyzer
inputs. All 14 channels are sampled at the same time and are displayed
together. This is better than separate instruments because the analog
and digital waveforms are acquired with the same sample clock assuring
accurate time correlation between the two. Even if you went through the
effort of cabling two individual instruments together, you would not be
able to get the samples to within 2 ns of each other, nor would the
triggering be so tightly coupled. Since the software displays the
oscilloscope and logic analyzer data on the same screen it stays
synchronized no matter how you scroll or zoom.

Cross Triggering
The MSO-9212 can trigger on a signal in either the digital or analog
domain. In the analog domain, triggering can be straight forward rising
and falling edge, or further qualified by pulse width and pulse count.
Glitches can be detected using pulse width triggering. Digital domain
triggering can use a 12 bit wide digital word or by using the advanced
serial trigger( I2C and SPI bus protocols).

Deep Acquisition Memory
The 2Mpt( two million points per channel) buffer lets you sample at
high speed while capturing long traces. Other instruments with short
memory buffers force you to degrade your sample rate and thus lower your
bandwidth. For example if you needed to capture a 100us event using a 1
GSa/s scope with a 2.5k buffer, you would reduce your sample rate to 40
MSa/s, or at best a bandwidth of 10 MHz!”. The MSO-9212 would let you
view that 100us event at 20GSa/s.
“The big buffer really saved me. With my last oscilloscope
I always had to balance recording time and time per division. With
Link’s scope I can record at the fast sampling rate and still see the
entire event.” Bob Mitchell, consultant. (beta tester)”
A vast amount of data can be captured in the large acquisition buffer.
Often there are many points of interests that are scattered throughout
the buffer. QuadVue provides 4 independent timing widows that allow you
to focus and analyze the analog and digital data on just the point of
interest, instead of constantly panning and zooming after each capture.
Each window can even have a different timebase. Since each timing
display widow can display its own set of waveforms, one can superimpose
mathematically operated data and history memory data on top of the most
recent data for quick analysis and comparison.
In this example 4 timing windows are being displayed. Window 1 is
showing the entire buffer. Window 2 is showing a zoomed in section
around the trigger (Red cursor) event. Windows 3 and 4 are each showing a
different part of the waveform and are zoomed differently.

High speed sampling
Fast 1GSa/s ADCs allow the MSO-9212 to acquire and resolve events as
narrow as 1ns. The MSO can simultaneous sample at 500Msa/S (2ns)
across all 14 inputs (2 DSO+12LA). 50Gsa/S (20 pS) sampling
resolution is available in RIS (Random Interleave Sampling) mode. On the
opposite end of the timebase spectrum the MSO can sample at 1Sa/S, which
equates to 2097152 seconds or to over 524 hours Seconds per
acquisition or 24.27 days.
The MSO-9200 also has an external clock input which is primarily
used when doing Logic Analysis but is useful when doing mixed signal
analysis or for pure DSO work.
With an analog bandwidth of 200Mhz and 50GSa/s, the MSO-9212 is the
new performance leader in its price range. By fully utilizing USB 2.0
Hi-Speed mode and variable size acquisition buffer, the MSO-9212 can be
adjusted to provide fast screen updates and a very responsive analog
oscilloscope like experience.

Channel History - Better than
Persistence mode.
The Oscilloscope can automatically save and display up to 30
previous captures. Each capture will be color coded with the
oldest ones fading away.
In this shot the blue trace represents the current capture. The
yellow traces are the 30 most recent captures. The older history traces
fade to black.

Spectrum Analyzer/FFT
The dual channel FFT has controls for FFT window, FFT type, FFT
resolution, frequency range filters, peak hold and min/max envelope.
The newest release of the software also supports averaging, memory
and plot subtraction. This allows for a whole range of spectral
analysis including: Frequency response analysis, Power supply noise
analysis, etc...
FFT data can be saved to disk and exported to other programs such as
Excel, Mathcad, etc....

Waveform Measurements
A powerful suite of over 40 measurements are available. The
measurements can be performed on incoming waveform, stored waveform or a
mathematically processed waveform. The data cursors can be used to
define a subset of data to be measured.
Pass/fail testing based on user specified criteria is also
supported. Data can be saved to disk based on the test results.

|
|
SPI decoding
The MSO-9212 can display and decode SPI bus protocols as
well as trigger on them.
SPI signals can also be viewed as timing waveforms and statelist
style display. Up to 3 SPI buses can be decoded simultaneously.
|
 |
|
|
I2C decoding
The MSO-9212 can display and decode I2C serial bus protocols as
well as trigger on them.
I2C signals can also be viewed as timing waveforms and statelist style
display.

Simple Operation
- Installation is a snap.
- Make measurements in your first half hour.
- Simple controls make operation intuitive.
- Perform sophisticated operations that you couldn't even dream of
doing with a knob based DSO.
- Save default setups to disk for easy recall at a future date.
- Screen shots can be pasted into documents and annotated in your
favorite image editing program.

Data averaging for increased accuracy
Trace data can be averaged over many captures to reduce noise and
increase accuracy. The average can be saved to memory, logged to disk or
reset after a specific number of captures.
|
|
|
Automatic Storage
To save time, you can automatically datalog waveforms to your PC.
Data can be stored after each capture or based on the results of pulse
measurements.

The windows oscilloscope software takes advantage of your computer's
large color screen.
Stand-alone oscilloscope display screens represent a compromise at
best. Few people would choose a 7" or 9" monitor as the screen for their
PC. So why use a small monitor for an oscilloscope? Many people are now
using dual monitor PC's - our software will work there also - Imagine
having a 30" wide trace window.

The speed of your PC does not significantly affect the
performance of our instruments
All of the high speed acquisition is done with the MSO hardware, the
speed of your PC is not a factor. The PC is used for display and
for the user interface. If your PC is fast enough and has enough memory
to run windows well, it will run our products well also.
The Instrument has high speed samplers and buffers. It can acquire at up
to 1 GSa/s and stores the data in it's own 2 MegaSample
data buffers. When these buffers are full everything is transferred to
the PC.

Software
Libraries
The optional DLL library
allows users to write custom software to control the instrument.
The library works with visual studio, labview and matlab.
