trigger problem
Re: trigger problem
Did you see trace at 0.2V/div with input floating?

Randoms triggers.
I have done more tests with Firmware 055 (old hardware)
If trigger mode is set to AUTO the trigger will be disabled and waveform is displayed in rolling style that waveform is constantly shifting from right to left.
I think it's not a trigger problem
I've put another oscilloscope connected to ADCIN
The gain I think works well
Is it a visualization problem? VPOS?
The problem is the same as with firmware 062. The visulization of the signal is either overflow or not seen
I have done several tests with different voltages i frequencies always with the same result:
-------------------------------------------------------------------------------------------------------
Test 1 with square wave V=0.45V ; 500 Hz
Photo 1; other oscilloscope ADCIN, Photo 2 DSO Shell
5mV -> -> (ADCIN change, gain is correct?)
20mV -> -> signal ?????
Vmax = - 415mV
Vmin = -415mV
Vavr = -415mV
Vrms = 415mV
???????
----------------------------------------------------------------------------------------------------------
other test V=5V ; 500Hz
50mV -> -> 0,1 V -> -> (ADCIN change, gain is correct?)
0,2 V -> -> signal ?????
Vmax = - 4.15mV
Vmin = -4.15mV
Vavr = -4.15mV
Vrms = 4.15mV

Re: trigger problem
Is it true that the issue happens on some particular sensitivity settings? If this is the case please check the signals SENSEL0 - SENSEL3.
