The MSO-19 is a 2GSa/s Oscilloscope, 200MSa/s Logic Analyzer, 100MSa/s Pattern Generator and a TDR. It is extremely portable and is only $249 (including probe, clips, wires and software). The Mixed SIgnal Oscilloscope connects to your computer via USB and is even powered by USB. All channels sample simultaneously at a max rate of 200MSa/s Our design goal for the MSO-19 was to make an MSO that students and hobbyists could afford but was powerful enough for professionals. We realized pretty soon that we could pack enough performance and quality into this product that it would appeal to a larg group of customers:
- Any engineer that needs a 2GSa Mixed Signal Oscilloscope(MSO).
- Field service technicians.
- Field application engineers.
- Anyone that needs a small travel scope or logic analyzer.
- Anyone that needs a powerful trigger box to use with other instruments.
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. Since the software displays the Scope 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-19 can trigger on the Oscilloscope, Logic Analyzer, SPI or I2C inputs. Since all of the 9 inputs sample at the same time they are displayed together.
Triggering options include:
- Trigger level rising edge
- Trigger level falling edge
- Pulse width and count
- 8 bit logic analyzer
- External trigger output. Use this to trigger other instruments.
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.
The 100Mpt/S pattern generator (Digital Word 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. Pattern generator options include:
- Output synchronized start with MSO.
- Output controlled by MSO trigger (Analog, digital, I2C or SPI).
- Variable pattern length.
- Independent pattern clock rate.
- Built in data creation wizard and option to load datafiles.
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 your favorite 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...).
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.
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.
