Title: USB DSO3204A Windows 10 Drivers
Where are the correct Windows 10 drivers located for an old style USB DSO3204A (250Mhz, 1.4ns, 4 channel with no digital IO ports). THe unit worked fine in Win 7 but when the computer was upgraded to Win 10, the USB drives apprear to no longer work. The driver package for a DSO3000 was installed (including the IO package) but did not correct the problem.

Thanks

Thank you for the link to the new drivers.

Are there any specific instructions to uninstall the old drivers and install the new ones?

Author: amy Time: 2016-8-19 17:11
Please refer to the document to install the driver.

I followed the instructions to remove the old driver. During the process, No DSO driver showed up in the Device Manager. I did remove the files from the windows inf and windows sys32 driver folders. But the problem is still the same. When I plug the 3204a USB cable into the computer, it chimes just like normal when you plug in a USB device but it does not ask for a new driver. When you launch the application it can not see the 3204a and ask about running in demo mode. From the time I upgraded to windows 10, the driver stopped showing up in Device Manager. But when you plug in the 3204a, it chimes just like the driver is already installed. How to I completely remove the old driver so that it will ask for the new one?

Dir sir,
Please tell me the S/N of your device. And when did you buy it?

Author: jcul3351 Time: 2016-8-21 00:10
Purchase date was 4-27-2014 on ebay from one of your resellers. The reseller is listed below. The serial number on the white tag on the back is V42000152

I have also confirmed the device does show up in the "printers and devices" section of the control panel. However when uninstall it and reinstall it, the new drivers still don't work.

I was able to get it working. Key things to do:

Uninstall the driver from Control Panel / Devices and Printers. (it does not show up in Device Manager)
Uninstall the DSO3204 software
Follow the Hantek PDF on removing the files from Window/INF and Windows/Sys32/Drivers
Reinstall the DSO3204 sofware
Plug in the USB scope
Let the drivers install (it still won't work if you run the 3204 application)
Critical - then go and update the drivers in Control Panel / Devices and Printers ensuring the update is pointed to the 2010 drivers provided by Hantek.

I would now seem to have a new problem. The DC gain on all 4 channels appears to be broken. I have run the calibration cycle many times. I have tried it with a cold unit (just turned on) and a warm unit after 30 min under power. No mater what I do, the 2v P-P reference wave is 5.8v p-p on all channels. I have confirmed this with external voltage references at well. The indicated voltage is about 3x of what is actually being measured. It would appear the internal voltage reference used to calibrate the amplitude has failed. The unit is just 2 years old with limited use. I am not sure what the warranty is. With the current failure, the unit is pretty much worthless. What are my options?

Author: amy Time: 2016-8-22 11:15
Sir,
The device can work on Win7 normally?
When you do self calibration, do you input any signal to 4 channels? Please don't input any signal to try.
About the voltage measurement, please give us a short video to study.

Author: jcul3351 Time: 2016-8-22 22:44
At one point the device calibrated correctly on Windows 7 BUT I have not gone back and tried that since upgrading the computer to Win 10. I currently do not have the software installed on a windows 7 machine. I will do some testing tonight and capture some video to send to you. I doubt Windows 10 had anything to do with the calibration issue. I would think that is all contained inside the 3204A.

Author: amy Time: 2016-8-23 15:27
OK, we are waiting for your video.

Author: jcul3351 Time: 2016-8-25 20:45
Amy:

Here is a dropbox link to the video. It shows the entire calibration sequence including moving the probe from the ground to the 2vp-p ref signal once the cal is complete. You will see the square wave on the screen show about 6vp-p. You will also notice at about 2:45 in the video, the application locks up. Unplugging the USB and re-plugging it recovers from the lock up. I have experience this issue ever since I received the unit. It that normal? The application also tends to lock up if I grab the trigger voltage symbol on the right side of the screen and slide it. The software version here is 1.0.8.

Please let me know what my options are to get these issues resolved.

Thanks

Jerry

Dir sir,
I want to send a software to you. Please give me your email.
Please install the latest software to try.
If not, please change a Win7 computer to try.
By the way, please unplug the probe to do self calibration.

Author: jcul3351 Time: 2016-8-26 21:20
For calibration the instructions say to ground the probe.  What do you mean when you say "unplug the probe"?

Is the latest software available online?  The software download link for the old DSO3204a had disappeared.

Windows 7 is really not a long term option.  If you wanted me to test it, I can but I really need this to work on Win10.

Is there a private way I can send you my email?  Or can you put the software in some public cloud where I can grab it?

Author: jcul3351 Time: 2016-8-29 23:43
Any response to my last post?

Author: amy Time: 2016-8-30 09:15
Dir sir,
For calibration, disconnect any probes or cables from the input connectors.
About the latest software, you can send a mail to support@hantek.com to get.
Please test it on win7, convenient for us to find the reason. Thank you for your cooperation.

Author: jcul3351 Time: 2016-8-31 00:13
I will test with Win 7. Stay tuned for the results.

Author: amy Time: 2016-8-31 08:57
Please keep us informed of the situation of this problem.

Sir, we had send the software to your email yesterday. Just sent again. Please check.

Author: jcul3351 Time: 2016-9-1 10:31
I have just checked all the junk mail filters and quarantine lists for my email address.  I do not find anything from Hantek in the last 5 days.

I have tested the email address in the post above and it does deliver email to my email address.  So it appears the address is correct.  Please check you spelling.

I have also conducted extensive testing tonight.  I believe the current software version I have for the 3204a is 1.0.8.

1. If you do not plug anything into the bnc connectors on the 3204a and then run the calibration procedure, the gain on each channel DOES calibrate correctly.  It was my mistake thinking the channels needed to be grounded.  The manual clearly states to remove all connections.
2. But the trigger voltages do not calibrate correctly.  And each time you run the calibration, they seem to calibrate differently.  The closest calibration happens if you calibrate right after startup (cold unit).  If you use the 2v p-p test wave form to trigger on and set everything to DC, the trigger calibration can be off 2 volts or more.  It will indeed trigger, you just need to move the trigger to a voltage that is outside of the displayed waveform.  This problem has existed since the unit was new.
3. If you are actively triggering on a waveform and then use the mouse to slide the trigger voltage (right side of the screen) or the voltage ref (left side of the screen) the software will lock up almost immediately. Normally before you slide the voltage even one division.  You an recover from this lock up by unplugging the USB connector and then plugging it back in.  You can also restart the software.  This problem has also existed since the unit was new but appears to be significantly worse with Win 10.
4. If you are actively triggering on a waveform and simply walk away (don't touch anything) the software appears to operate correctly for at least 30 min.  If you touch either of the voltage sliders (trigger or volt ref) the software locks up almost immediately.

With the exception of the lockups being more frequent, I am basically back to the functionality I had in Win 7.

Please double check my email address and resend.

There are limited email filters on that address.

Jerry,
thanks for your descriptions, it helped me running my 3204A on Win10.

I have the same lock-up issue, could you solve it?
On my System calibration does not do anything, it just says "calibrating" for hours.

Regards
Beat

Author: amy Time: 2016-9-5 10:24
Dir sir, we had send the software to your new email in September 2, and you told me you had received.
Please use the new software to test. If the problem exusts, please give us a short video to study.
For accurate calibration, power on the oscilloscope and wait twenty minutes to ensure it is warmed up.

Update:

I did receive the DSO3204a 1.0.10 software.  After extensive testing here is what I have learned

1. The trigger calibration issue seems to be 95% resolved.  It is not perfect but it does work well enough to be useful.
2. The software will still lock up when adjusting the trigger voltage by moving the slider on the right hand side of the screen.  I have made these observations
a. If the scope is plugged into a USB3 port, the lock up happens very quickly and there is no error message.  You can recover by unplugging and replugging the USB connector
b. If the scope is plugged into a USB2 port, the lock up does not happen as often AND when it does you get a pop up error message.  You can still recover by cycling the USB plug.  I have included a screen shot of the error.
c. If you move the trigger voltage slider VERY slowly, it will not lock up.
3. When you select CALIBRATION a window pops up allowing you to select the channels you want to calibrate. On that screen it instructs you to "GROUND THE PROBES" during calibration.  The manual states "remove everything from the BNC connectors".  Pretty confusing.  That is why I had been grounding the probes during calibration.  I have included a screen shot of this as well.
