DSO2D15 freeze

Jing

Customer consultation

I just received my new Hantek DSO2D15 Digital Storage Oscilloscope.

When I adjust the vertical position knob, the Oscilloscope freezes.
I installed the latest firmware from your site, but this does not fix the problem

there are several types of firmware out there (it's different from software). The most common types include:
1) 3000
2) 3200
3) 3102
4) 3202

you may also find the following unique types:
A015 etc

So, it's better for you to check your firmware first before upgrade: 3000 upgrade to 3102, whereas 3200 upgrade to 3202

Dear Sir
Hi.
I have Model DSO2D15
Serial CN2101029001583
Software 1.0.1.1.0 (20210416.00)
Equipment 000.000.000.000.000.000.000.001
Firmware 3000
Unstable sync
You sent me an email dso3kb_20210714.
Hanging issues disappeared, but not stable signal sync in Falling mode.
Do I need to apply dso3kb_20210630_auto_update_fpga or can't I?

Apparently, unstable synchronization is present for everyone, I also have it and the firmware does not affect.

Apply dso3kb_20210630_auto_update_fpga.
Firmware 3000 has not changed to 3202.
How do I change Firmware 3000 to Firmware 3202?

Applied dso3kb_20210601. Firmware 3000 has been replaced with firmware 3102.
Thanks, synchronization is normal!

Where is the video and how you will convince us that you will solve software problems with just adding a fan. DSO2D15 have a lot of work on software to become acceptable product. Hanging when move vertical position of CH1 is fixed, but trigger sync is bad, generator is just to be there and attract costumers. No bode plot, decoder is not good. It is cheap, ok, but in my opinion is far away from acceptable measurement equipment.
