MSO-19 Oscilloscope, Logic Analyzer, Pattern Generator
A Mixed Signal Oscilloscope (MSO) is a combination Logic Analyzer and Oscilloscope. Since all inputs sample simultaneously, it is easy to see the timing relationships of the digital and analog components of your circuit. The extra channels also allow for more complex triggering. All of our MSOs have Oscilloscope triggering, Logic Analyzer triggering, SPI triggering and I2C triggering.
The MSO-19 appeals to a large audience, including:
- Engineers who need a 2GSa/s Mixed Signal Oscilloscope
- Students
- Hobbyists
- Field service technicians
- Field application engineers
- Consumers who need a small travel scope or logic analyzer
- Those who require a powerful trigger box to use with other instruments
- Advanced triggering

Dimenstions
All 9 channels are sampled at the same time and displayed together. This is better than using multiple separate instruments because the analog and digital waveforms are acquired with the same sample clock, assuring accurate time correlation between the two. Even through cabling two individual instruments together, samples would not be within 5 ns of each other, and the triggering would not be as tightly coupled as it would be with a single instrument.
Since the software displays the oscilloscope and logic analyzer data on the same screen, it stays synchronized no matter how much a user scrolls or zooms.
MSO-19: Time-Synchronized Oscilloscope and Logic Analyzer Inputs
The Logic Analyzer display can show individual pulse width and frequency information.
Triggering options include:
- Trigger level rising edge
- Trigger level falling edge
- Pulse width
- 8 bit Logic Analyzer
- SPI
- I2C
The MSO-19 can trigger on the Oscilloscope, Logic Analyzer, SPI or I2C inputs. All 9 inputs sample at the same time, and they are displayed together. The external trigger can be used to output to trigger other instruments.
Advanced Triggering
High-speed sampling is key to getting a good capture. An accurate capture of a 60 MHz signal can be obtained with the 200 MSa/s single shot sample rate and 60 MHz bandwidth. With RIS mode sampling, one can capture even faster signals.
HIgh-Speed Sampling
This example shows use of FFT averaging to identify and reduce noise.
The FFT Spectrum Analyzer has controls for FFT window, FFT type, and 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.
The maximum FFT frequency analysis is 100 MHz.
FFT data can be saved to disk and exported to other programs such as Excel, Mathcad, etc.
Spectrum Analyzer / FFT
Pattern generator options include
- Output, manual start
- Output, synchronized start with MSO
- Output, controlled by MSO trigger
(Analog, digital, I2C or SPI) - Variable pattern length
- Pattern clock rate -- independent of LA clock
- Built-in data creation wizard and option to load data files
The 100 Mpt/S pattern generator (Digital Word Generator) has many features not found on other pattern generators. Because it has shared pins with the Logic Analyzer, the pattern data can be tri-stated to create bidirectional bus signals.

tandard waveform measurements are included and can be displayed on the screen right next to the traces.
Measurement results can be saved with the data files
Waveform Measurements
The MSO-19 can 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 displays.
SPI and I2C Decoding
- Perform sophisticated operations that cannot be done 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 a preferred image-editing program.
- Fast installation.
- Quick measurements.
- Simple controls make operation intuitive.
Simple Operation
- Data can be exported in "CSV" format to programs like Matlab, Excel, Word, etc.
- Users can paste screen images into their reports using programs like Word, Excel, image editors, etc.
- Data can even be shared with other computers. One can capture data in the lab and view it in your office or e-mail it to other engineers at remote locations for analysis. There is no need to be connected to our instrument in order to view a file.
Data Storage
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? Our software will also work with dual-monitor PCs. Imagine having a 30" wide trace window!
Link's Windows-Based Oscilloscope Software Takes Advantage of a Computer's Large Color Screen
The instrument has high-speed samplers and buffers. It can acquire information at up to 200 MSa/s and stores the data in its own internal data buffers. When these buffers are full, the data is transferred to the PC.
All of the high-speed acquisition is done with the MSO hardware; the speed of a PC is not a factor. The PC is simply used for the display and user interface. If a PC is fast enough and has enough memory to run Windows well, it will also run our products well.
