Mixed Signal Oscilloscope - small and portable
The MSO-28 is a 2 GSa/s Oscilloscope and 200 MSa/s Logic Analyzer. It is extremely portable. At only $325 it includes probes, clips, wires and software. It connects to your computer via USB. Our low power architecture eliminates the need for an external power supply. All channels sample simultaneously at a max rate of 200 MSa/s(5ns).
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 Logic Analyzer display can show pulse width or frequency for individual pulses.
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.
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
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... 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.
Standard waveform measurements are included and can be displayed on the screen right next to the traces.
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.
- 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 ofdoing 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 yourfavorite image editing program.
Data can be saved to disk and reloaded in the future or exported in CSV format for use with other software (Excel, Mathcad, etc...).
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.
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.
