Logic Analyzer
Spectrum Analyzer



The MSO-28 is highly portable. It operates as both a 2 GSa/s Oscilloscope and a 200 MSa/s Logic Analyzer. All channels sample simultaneously at a max rate of 200 MSa/s.

At only $325, it includes probes, clips, wires, and software. It connects to your computer via USB.

The MSO-28 features a low-power architecture that eliminates the need for an external power supply.

The MSO-28 appeals to a large audience, including:

  • An engineer that needs a 2GSa/s Mixed Signal Oscilloscope
  • Students
  • Hobbyists
  • Field service technicians
  • Field application engineers
  • Someone that needs a small travel scope or logic analyzer
  • Someone that needs a powerful trigger box to use with other instruments

MSO-28: Time synchronized Oscilloscope and Logic Analyzer inputs.

All 10 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.

The Logic Analyzer display can show pulse width or frequency for individual pulses.

Advanced triggering

The MSO-28 can trigger on the Oscilloscope, Logic Analyzer, SPI or I2C inputs. All of the 10 inputs sample at the same time. The end result is a fully synchronized display of all the digital and analog inputs. Use the external trigger output to trigger other instruments.

Triggering options include:
  • Trigger level rising edge
  • Trigger level falling edge
  • Pulse width and count
  • 8 bit Logic Analyzer
  • SPI
  • I2C

High speed sampling

High speed sampling is key to getting a good capture. You get an accurate capture of a 60 MHz signal with the 200 MSa/s single shot sample rate and 60 MHz bandwidth. With RIS mode sampling, you can capture even faster signals.

Spectrum Analyzer / FFT

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.

Waveform Measurements

Standard waveform measurements are included and can be displayed on the screen right next to the traces.

SPI and I2C decoding

The MSO-28 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 display.

Simple operation

  • Installation is a snap.
  • You're able to make measurements in no time.
  • 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 exported in "CSV" format to programs like Mathcad, Excel, Word, etc.
  • You can paste screen images into your reports using programs like Word, Excel, image editors, etc.
  • Data can even be shared with other computers. You can capture data in the lab and view it in your office or e-mail it to other engineers at remote locations for analysis. You don't need to have our instrument connected to view a file..

Link's Windows-based 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 its own 2 MegaSample data buffers. When these buffers are full, everything is transferred to the PC.
