What is an oscilloscope meant to do? My research into the etymology of the word oscilloscope suggests that it is a device for observing, or examining, signals that swing, or oscillate.  At least that was the essence of the definition at the time oscilloscopes were first invented.  Modern oscilloscopes still allow swinging signals to be examined, but they do so much more thanks to advances in measurement technology and the inclusion of plenty of computational horsepower.  Still, ...
I have two basic criteria that have to be met before I will apply for a roadtest: The item being roadtested needs align with my interests and it needs to provide sufficient value relative to the amount of effort that would be required to roadtest it.  This could range from simple lower value items that don't require a lot of time invested to roadtest to very complex high value items that require significant effort and time. I need to think that I have the capability (knowledge and equipme ...
Hello community members!   I have spent a few hours exploring the MSOX3034T, just enough time to get acquainted with its general behavior. I set it up next to an oscilloscope I know very well; the Tektronix MDO4104-3.  The photo below shows the two instruments on my bench.   My review, when posted, will include comparisons between these two oscilloscopes.  The two instruments are not direct competitors.  A 4000 series instrument has different features than a 3000 seri ...
This is the fifth instalment in a series of blog posts to support a RoadTest Review of the ACCESS:bit for micro:bit. The review is being conducted by a student from a high school computer club. Details on how the RoadTest is being conducted can be found here RoadTest Support: ACCESS:bit for micro:bit The Application   Our RoadTest review team is happy to report, the ACCESS:bit is working. The student was experiencing some problems detailed in the last blog posting RoadTest Support: ACCESS: ...
This will be the last hardware design performance test that I'll be running for the roadtest.   This is the SATA performance test: UltraZed-EV-RD-SATA_Performance The link provides a pre-built PetaLinux image with an included test script drive-test.sh that facilitates running SATA drive read/write and I/O performance tests.  The test script encapsulates the following 3 tests: dd - This utility is from the Coreutils Linux package and is a very simple tool which can be used to perform ...
Hello Everybody!   This is my first blog post part of my RoadTest of the Keysight InfiniiVision MSOX3034T Mixed Signal Oscilloscope (MSO).   First of all, thank you Keysight and Element 14 for providing me this great instrument! I'm pretty sure it will useful in a lot of my future projects.   1. Unboxing & First Look  So, Thursday morning UPS delivered me the shipment from Element14. This was one day earlier than expected, so I was super excited.   The shipment ...

I'll need to do this road test in parts, because it may get complicated. The first task is installation.  This will require removal of the existing breaker and replace it with the Power Defense breaker. The PDG23F0060P2MJ is a frame size larger than the existing breaker, so that may be a challenge. Here is the existing breaker: Here is the enclosure: The PDG23F0060P2MJ arrived in a well packaged box. The contents were a PDG23F0060P2MJ, 4 mounting screws, a manual of sorts, a ...
I am continuing to run through existing performance tests in parallel with starting to integrate the elements of my project.   This is the network performance test: UltraZed-EV-RD_Ethernet_Performance_Test The performance tests use iperf3: https://iperf.fr/  which is a tool for performing network throughput measurements by testing either TCP or UDP throughput.  The tests require iperf3 to be running on two network endpoints - a client and a server.  The link above provides ...
I had mentioned in a prior post that I was having a bit more trouble using GStreamer than I had anticipated.  I had some problems using the udpsink and udpsrc elements that were used for the RTPStreaming demo.  It turns out that was actually caused by my prior GStreamer experience.  I've used GStreamer, VLC, and OMXPlayer a fair amount as clients to receive RTSP streams from IP cameras.  I'm used to the client sending a request to the server (camera) when it wants to start re ...
This is the forth instalment in a series of blog posts to support a RoadTest Review of the ACCESS:bit for micro:bit . The review is being conducted by a student from a high school computer club. Details on how the RoadTest is being conducted can be found here RoadTest Support: ACCESS:bit for micro:bit The Application   The objective for this week was to program the ACCESS:bit and have the barrier move. The student was not successful in achieving that objective. The barrier does not move whe ...
