MSO-28 USB 2GSa/s Oscilloscope and 200MSa/s Logic Analyzer
We're sorry this product has been discontinued. Please choose from the menu on the left for alternative products.
The MSO-28 is a portable USB based 2GSa/s Oscilloscope and 200MSa/s Logic Analyzer. All channels sample simultaneously at a max rate of 200MSa/s (5ns), includes probe, clips, wires and software. Windows XP/Vista/7. The MSO-28 has 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 MSO-28 can trigger on the Oscilloscope, Logic Analyzer, SPI or I2C inputs. Since all of the 10 inputs sample at the same time you will see a fully synchronized display of all the digital and analog inputs. 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. 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.

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.
MSO-28 Deployed
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.
Spectrum Analyzer/FFT
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 1: Spectral plot of noisy output of an Op Amp circuit. 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.
Big Screen Picture
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.
