PiMSO, is a Raspberry Pi controlled 200Msa/s mixed signal oscilloscope.  PiMSO, a spinoff of WebMSO, is an experimental project to understand the necessary components required to deploy the MSO-28 mixed signal oscilloscope on mobile devices.

The PiMSO lets you run a USB based Oscilloscope/Logic Analyzer from a Raspberry PI. The Oscilloscope is controlled via the browser on phone, tablet, PC or MAC. The connection to the host is via WIFI or Ethernet.  PiMSO consists of eight parts:



The MSO-28 is a 2 GSa/s Oscilloscope and 200 MSa/s Logic Analyzer. It is extremely portable.

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.

Add a RaspberryPi or Intel Edison for remote operation via the web.  Control the MSO-28 remotely from your Android, IOS or web browser.

hp or  Hewlett-Packard  started as a T&M Firm.  Agilent  Technologies continued the Instrumentation Products after hp became a computer company.  Now Keysight Technologies is the new name for the Instrumentation Division. Agilent now is a Life Sciences company.



"From a small garage in Palo Alto, California, to employees around the world serving customers in 110 countries, Agilent has a long history of innovation and leadership in the communications, electronics, semiconductor, test and measurement, life sciences and chemical analysis industries."

Keysight Technologies - Test and Measurement - https://www.keysight.com/

The company founded by William "Bill" Redington Hewlett and Dave Packard was know as Hewlett-Packard Company or HP. This was a Test and Measurement company. First popular product was a precision audio oscillator, the Model HP200A.

Later Computer and Printer products divisions retained the brand and firm and Agilent was spun off for for the Test and Measurement and other non-computer product line.
