Part of my job at element14 is to manage the Roadtest program. That entails lots of every day activities such as speaking with suppliers about the products that they would like to roadtest or creating roadtest pages or even answering all kinds of questions. I also try to find ways to improve the program. To do this, I often create discussions and polls to get your feedback and your ideas on how to make things work better. With these things, I usually find out what I am doing right and sometimes ...
Here is a run up of all my thoughts and experiences during this RoadTest...   The MAX31889 is quite a powerful chip, with great accuracy levels and precision.   I was quite disappointed to see that Windows 7 was not supported even though the website claimed it was.   Maxim Support has promised to look into this.   The MAX31889 is also low cost- less than 3 dollars in quantities of one(found on Newark, at time of writing, in USD), which is quite inexpensive and has signifi ...
I2C Testing (continued from Picoscope 6424E Road Test - I2C Serial Decoding )  Keen followers of my Picoscope 6424E Road test blogs will have noticed that I rather messed up on the I2C decoding by having the 6424E connected to my PC via a USB 2 only port. Sorry about that ! But every cloud has a silver lining and the problems with the slow connection made me look a lot deeper into buffers and how they work than I might have done otherwise. And I had meant to get round to looking at the ...

Hi All.   I wanted to make a brief announcement about something we are rolling out in November.   We will be adding a Reliable Roadtester Badge to all the other badges a member can earn on the element14 community.   The badge is our way of saying Thank You to the roadtesters. We wanted to officially recognize those member who have really put fantastic efforts into doing roadtests.   This badge will be automatically awarded when a member completes and publishes three road ...
Most modern scopes offer some kind of serial data stream decoding. Many supply it as a paid for optional extra although special offers where some decoders are bundled with the instrument are common. Pico have an unusual approach - all the serial decoders are bundled into the standard Picoscope 6 software and, hardware permitting, they work across the range of Pico's scopes. The range is quite good: Pico's decoders work on captured data which has been moved to the PC for processing. This mea ...

The 6424E can accept one or two TA369 Digital Pods to extend its capabilities by up to an additional 16 digital channels. This is a nice simple conversion from 4 channel analogue to 4 + 16 MSO functionality for which you need only to buy the Digital PODs (no additional software or licenses required.) The TA369 Pods are very nicely made and I think rather better designed than the similar pods that can be added to the Keysight 3000 series or the Rhode and Schwarz RTA4000 series scopes. The TA3 ...

Before tackling the actual review document for the PicoScope 6424E Oscilloscope + Accessories I was encourage by other blog posts about the 6424E to try another test. The motivation for this additional testing was after reviewing the the blog post Picoscope 6424E RoadTest - Testing a power supply  done by michaelkellett . I recalled a E14 series  Workbench Wednesday 25: Measuring a MOSFET’s Miller Plateau  , a look at the switching of a FET. I was fascinated by the knowledge ...
In my last Picoscope 6424E RoadTest blog I was testing a power supply which uses a hand wound custom transformer. shabaz asked about the transformer, and specifically how it might behave at lower frequencies (25kHz a rather than the 150kHz I tested at.)   It's not easy to test the transformer in situ in the PSU, so I would need to make another one to test it and that meant that I might as well design a new one just for testing. The 6424E has some tricks up its sleeve which helped a lot w ...
In this blog I'm going to describe using the 6424E to look at various aspects of the working and performance of a switching power supply. The power supply has been designed for the Earth Resistance meter project which hangs out in Open Source Hardware using the ARMP tag. (Just search for ARMP). In order to understand what the scope is up to in this blog, it's necessary to understand the power supply it's testing - so we'll start with that: It's quite an unusual power supply. It has to provid ...
This is a blog post in support of thePicoScope 6424E Oscilloscope + Accessories . It is the eight and final blog post in a series exploring the equipment in order to generate the content for the final RoadTest review.   The operating system (O/S) I primarily use is Linux. Being retired, the requirement for me to work in the Microsoft Windows Operating system is greatly diminished. I rarely open the O/S. I was concerned when I applied for the RoadTest Review regarding testing in MS Windows. ...
As part of my Eclypse Z7: Zynq-7000 SoC Development Board - Review  road test, I'm hoping to investigate further into the Zmod add-on board ecosystem. Whilst Digilent call their board Zmods, these are based on the open SYZYGY specification. Let's just clarify what the difference is.   What's a Zmod? Zmod is a term created and used by Digilent. If you look at their documentation they describe Zmods as follows: The Zmod™ family is Digilent's line of peripheral modules that conform ...

One of the optional extra supplied with the 6424E was the probe positioning system. This is a serious attempt to address the issue of multi channel board probing. I had a quick look on the web and found several companies offering  probe props (ranging from simple plastic things to more clothes-peg like efforts), articulated probe holding arms and even full on powered XY platforms. I found just one system quite like the Pico PPS but it uses truly horrible open frame probes.   Pico's PP ...

The 6424E is a 4 channel screenless mid-range scope with built in signal generator and up to 16 16 channel digital inputs. It’s part of Pico’s 6000 family which is described in some detail here: www.picotech.com/oscilloscope/6000/picoscope-6000-overview The 6424E is not quite the top of the range, they also offer an 8 channel version as well as slower and lower resolution variants. It has a huge built in memory of 4Gs (depending on resolution and function) and a respectable sampli ...
Trial of Lithium Polymer battery with the MAX32630FTHR feather.   The MAX32630 has a PMIC onboard, for 100mAh charge rate, with a JST PH 2.0 connector to connect a battery, like the feathers from Adafruit.   I didn't have any of such connectors at home, so I asked Dan and Randall to get me them, and crimps and housings showed up at my door a few days later.   I did have some lithium polymer batteries, from GPS's I dismantled. These batteries are 10-12 years old.   I would ...
What is this blog about? Back in June rscasny was looking for people to experiment with thermocouple connectors. I got selected and connectors were dispatched. However they did not arrive until mid August. Meanwhile I was designing a PCB for the connectors (they are designed to be PCB mounted). I designed the connector footprint according to the datasheet, so they fit, but now that I see how they fit, I would design the foot print slightly differently to make them easier to hand solder. When ...
