Hantek DSO5102P Trigger Level Issue

Mikhail

Hello,

I have just bought a new Hantek DSO5102P oscilloscope. I realized the showed on the screen trigger level in EDGE mode is not equal to the real trigger level.

I can reproduce the issue:

- default setup

- warm-up the oscilloscope (30 min)

- make the self-calibration

- connect the probe tip channel 1 to the PROBE COMP connectors

- make setup as in the picture

The real trigger level in this picture is about 1.00 V, but the showed trigger level is 1.50V.

Additional oscilloscope information:

My questions:

1. Can it be a hardware problem in my oscilloscope?

2. Is it a firmware problem? (maybe the issue has been already fixed in the late versions, but I cannot upgrade the firmware because I will take the oscilloscope back if it is a hardware problem)

3. Maybe I do not understand the issue,and the situation is normal (but it is very uncomfortable for using)

Thanks in advance for your answers.

Mikhail

1.5 V - showed trigger level.

Real trigger level is 1.0 V:

I realized that it depends on the vertical position of the channel. The issue can be on a rising and falling edge depend on the vertical position tuning.
