0 m72 Posted February 15 Author Share Posted February 15 Hello! WaveForms 3.21.27, Digital Discovery. When trying to turn on the power supply, this error appears and WaveForms tries to reconnect to the device. But same setup works fine with the previous version of WaveForms 3.21.26.

0 m72 Posted April 5 Author Share Posted April 5 (edited) Hello! WaveForms 3.22.15, AD2 & AD3 Buffer accumulation in the oscilloscope does not work. Immediately after selecting an oscilloscope, the buffers are filled to the specified amount as provided. After each change of scale, movement of a curve, etc. the number of the scanned buffer is reset. After this sequence, the capture of several buffers stops. The counter shows a maximum of 1-2-3 buffers. 1. View digital 2. Digitizer: analog only. 3. Add: UART Sс С1 with default parameters. 4. Connect valid source of UART signal to channel 1. After this, you can do whatever you want, but the number of captured buffers will be constantly reset. You can close Digital view or so on. But if you remove the UART from the list of decoders everything works as it should again. Another strange thing is that this seems to happen only with UART decoder when valid sequence occurs. If the UART signal is always zero, the buffers are counted correctly. With best regards, Mikhail. Edited April 5 by m72 Link to comment Share on other sites More sharing options...
0 attila Posted April 8 Share Posted April 8 Hi @m72 Set the UART Baud to Manual. With Auto the Rate is recalculated for each capture which is handled as configuration change and the Buffer counter is restarted. It will be corrected in the next version. m72 1 Link to comment Share on other sites More sharing options...
0 m72 Posted June 13 Author Share Posted June 13 Hello! Digital Discovery, Windows 10 x64, WF 3.22.20 and above The base frequency is not controlled. 1. Base frequency 100 MHz. Pattern generator. 1 kHz clock. The multimeter shows 1.000 kHz. 2. Set the base frequency to 80 MHz. 3. The multimeter shows 1.250 kHz. With best regards, Mikhail.

0 attila Posted June 13 Share Posted June 13 Hi @m72 It is working for me with 3.22.20 and latest m72 1 Link to comment Share on other sites More sharing options...
0 m72 Posted June 13 Author Share Posted June 13 (edited) It is very strange. I am sending "U" (0x55) via UART 115200 8N1. I checked it on two DDs - the result is the same. With version 3.22.19 everything works fine. P.S. After several reconnections everything worked fine with 3.22.24. But the result is unstable.

0 attila Posted June 13 Share Posted June 13 I also tried 2 DDs but I can't reproduce it. In 3.22.20 direct trigger on any DIO/DIN was added to the device configuration. If it was a timing issue, it should show up at higher frequencies, but it seems to work even overclocked to 125MHz. This frequency adjustment is useful if you want to generate or capture at high rate which is not derivable from 100MHz, like to generate 40, 48MHz... use 80MHz or 96Mhz or capture at 640MHz and not at 800, 400MHz...

0 m72 Posted June 14 Author Share Posted June 14 (edited) The effect appears and disappears when the DD is reconnected. It looks like there should be a long pause before reconnecting. More than 10 seconds. Then something inside the DD is completely discharged and it starts in normal mode. If the pause is less than 5 seconds, then how lucky. With version 3.22.19 this effect does not occur at all. Edited June 14 by m72 Link to comment Share on other sites More sharing options...
0 attila Posted June 14 Share Posted June 14 This seems to be USB cable contact issue, at least the same error is generated on disconnect. Do you see device re-connect event in the system when this error shows up ? Have you tried to use a different port, cable ? I've never seen problem related to this, but I'll try to rebuild the configuration with stricter communication constrains for the next software version. m72 1 Link to comment Share on other sites More sharing options...
0 m72 Posted June 15 Author Share Posted June 15 Apparently I didn't describe the situation very clearly. The DD is constantly connected to the computer and they turn on simultaneously. The cable is good, tested over the years. It even works with AD2, which has more stringent power requirements at the start. Recently I needed a base frequency other than 100 MHz and I noticed this oddity. DD was on the wire from the moment the computer was turned on. Thinking that the problem was in the cable, I started reconnecting the DD to different USB ports. The problem appeared and disappeared randomly. Being in another place, I discovered the same effect with other DDs, a computer, a different version of Windows and a cable. Then, out of habit, I tried to roll back WaveForms several versions back and found that with version 3.22.19 everything works fine in any combination. I even tried to reinstall the WF without changing the circuit or reconnecting the DD and the effect disappeared if I rolled back to 3.22.19 and returned with the installation of 3.22.24. And only on the third day I caught a pattern in one place: a short disconnection of the wire is a failure, a long one is the norm. In the video, I manually reconnect the DD to the same USB port. The pattern is so clear that I shot the video almost the second time. However, on another computer, reconnecting does not change anything. Base frequency only works correctly with version 3.22.19.

0 attila Posted June 17 Share Posted June 17 Hi @m72 Sorry I thought the disconnect is a new failure... I still haven't been able to reproduce this frequency issue. If the frequency is not configured properly, a 'not locked' warning is show on connection to the device. It is not show with auto-reconnect, which can be disabled under settings/options/device. Eventual lock problem is also show when adjusting the frequency under settings/option/clocking, at the bottom of the dialog. m72 1 Link to comment Share on other sites More sharing options...
0 m72 Posted June 17 Author Share Posted June 17 Hello! A confusing case. I have disabled automatic reconnection. Now after that I separately select and launch the device. But still, with some probability, the frequency setting does not work. If the frequency was set on the first try, it will work until the next reconnection. If the frequency has not been set, this will also last until reconnection. The picture shows the reference signal of an oscilloscope with a frequency of 1 kHz (indicated by markers). According to WaveForms, there is no frequency setting error. With best regards, Mikhail. Link to comment Share on other sites More sharing options...
0 m72 Posted September 23 Author Share Posted September 23 Hello! WF 3.23.18, AD3 The signal level statistics to the right of the oscilloscope window are displayed incorrectly when the offset is different from zero. With best regards, Mikhail.

Question
m72
Hello!
Can be "Logic Detector" added to trigger menu in "Scope" instrument?
I use this workaround in WaveForms V3.11.7 (beta, Windows, 64 bit):
1. In AD2 settings set "Trigger 1" to "Logic Detector"
2. In "Scope" use "Trigger 1" as trigger.
With best regards, Mikhail.
