The MSO-19 has time synchronized oscilloscope and logic analyzer
inputs. All 9 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 5 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.

Advanced Triggering
The MSO-19 can trigger on the Oscilloscope, Logic Analyzer, SPI or
I2C inputs. Since all of the 9 inputs sample at the same time you will
see a fully synchronized display of all the digital and analog inputs.
Oscilloscope trigger: Rising edge, falling edge and pulse width.
Logic Analyzer trigger: 8 bit trigger word
SPI trigger: 32 bit trigger word
I2c trigger: 32 bit trigger word

Pattern Generator (Digital Word Generator)
The 100Mpt/S pattern generator has many features not found on other
pattern generators. Since it has shared pins with the Logic
Analyzer the pattern data can be tri-stated to create bidirectional bus
signals. The PG also runs on an independent clock from the logic
analyzer, hence you can create a slow signal and analyze the response at
a much faster sampling rate. The pattern buffer length is
adjustable and can be looped to create complex patterns. The PG
can start
manually or be synchronized with the MSO trigger inputs.

High speed sampling
High speed sampling is key to getting a good capture. The
200MSa single shot sample rate and 60MHz bandwidth will allow you see a
great picture of a 60MHz signal in single shot mode and an even faster
one if you use RIS mode sampling.

Spectrum Analyzer/FFT
The FFT Spectrum Analyzer has controls for FFT window, FFT type, FFT
resolution. 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...
Maximum FFT frequency analysis speed of 100 MHz (with 3dB
roll-off at 60MHz).
FFT data can be saved to disk and exported to other programs such as
Excel, Mathcad, etc....

This example shows use of FFT averaging to identify and reduce noise.

Image 2: Average after 100 captures of the same circuit. Notice how
clear the fundamental and harmonic frequencies are displayed and the
random noise is suppressed.

Image 3: The noise source was identified and removed.

Waveform Measurements
Standard waveform measurements are included and can be displayed on
the screen right next to the traces.
|
 |
|
SPI and I2C decoding
Display and decode SPI and I2C serial bus protocols as
well as trigger on them.
SPI and 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 Storage
Data can be saved to disk and reloaded in the future or exported in
CSV format for use with other software (Excel, Mathcad, etc...).

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 high speed
data buffers. When these buffers are full everything is transferred to
the PC.
