Wayne Contello Posted August 27, 2020 Author Share Posted August 27, 2020 for the row I have highlighted, is there a way to create a new row where I trade number of channels for more depth? 8 x 32k? 4 x 64k? 2 x 128k? Link to comment Share on other sites More sharing options...
attila Posted August 27, 2020 Share Posted August 27, 2020 Hi @Wayne Contello Such device configurations are not available but you could use Record mode and Data Compression to capture large amount of samples, for typical communication data, signals burst.

Wayne Contello Posted August 27, 2020 Author Share Posted August 27, 2020 I look at that. thanks for responding! Is this for post processing? I am interested in looking at a long exchange of I2C messages. Link to comment Share on other sites More sharing options...
attila Posted August 31, 2020 Share Posted August 31, 2020 Hi @Wayne Contello The Logic and Scope recording streams data for long captures with rate limitations due to USB bandwidth. You can also use the Protocol I2C Spy if you are interested only in the I2C data and not it the signal timing: Link to comment Share on other sites More sharing options...
Wayne Contello Posted March 4, 2021 Author Share Posted March 4, 2021 Hi Attila, I am revisiting this topic again. My situation is that I am trying to capture both a single Scope channel (current) and several channels on the Logic Analyzer I2C (SCK and SDA) as well as a UART (TX from device). I need high enough resolution that the protocol analyzer can parse the signals from the Logic analyzer and, at the same time, high enough resolution to see the current spike at the start and end of an operation. The puts the configuration in conflict between the scope and the LA. I would be very willing to trade memory space from other devices (wavegen or patterns) or give up channels on the LA. From my previous exchange, I am not clear whether is is possible and undesirable for you and your team, or whether it is just not possible, I can share a screenshot once I get set back up. I should taken on yesterday where the scope was suggesting on configuration and the LA was suggesting another. I was running on 3.16.13. Wayne These are intended as constructive criticism. I appreciate this product and your efforts PS. I notice in the mac finder that the waveforms version is NOT shown in the get info window (select file, then use the Finder menu item "File > Get Info") PPS: On the forum where you post the beta updates, the forum topic does not reflect when the last updates occur And each entry in the post do not give a date, so it's hard to know when a post was made. In addition, it is not clear to me that, for instance, the macOS X version gets all the feature you describe when only a windows version is released.

attila Posted March 5, 2021 Share Posted March 5, 2021 Hi @Wayne Contello The recording in Logic Analyzer can use data compression, so it can capture at higher sample rate than the USB streaming would allow for raw data. The maximum rate depends on the signal activity, the average toggle rate should be max about 1MHz. pic 1 If you are interested in analog peaks you can use Min/Max sampling mode. pic 2 You can use Scope in mixed mode (with Logic Analyzer embedded) to capture or record data simultaneously. pic 2 You could perform normal capture in Scope at low rate and record at higher rate in Logic Analyzer. This to have more streaming bandwidth for digital data. The instruments can be synchronized with the triggers. pic 3 I could build a configuration with 8k scope and 16k logic buffer, but I don't think this would help you. The version info is not added to macOS app. I'll have to write a script to add this to Info.plist For now it can be seen in the Help/About or in the status bar of newer beta version. The beta forum post is not the most sophisticated solution. The Edited label at the end of the post indicates the last version release. I will add date note from now on. You can use the Help/Check for Update or Settings/Options/Application/Update rate Thank you for the observations. Link to comment Share on other sites More sharing options...

So the buffers must be large enough to hold the data until the next 1ms interval where data can be emptied. Maybe that is too high level. I would totally be willing to test for you. I don't know if the added configuration is a lot of work. If it is a lot then I would agree not worth effort. Link to comment Share on other sites More sharing options...
attila Posted March 5, 2021 Share Posted March 5, 2021 Hi @Wayne Contello I'm building it. It will be in the next software version. Link to comment Share on other sites More sharing options...
