Reverted to Ubuntu 18.04 on Dell Vostro 64 bit machine.
Re-downloaded openhantek-master from Github once more, and re-compiled.
Cmake failed with the comment that Policy CMP0072 was not known to this version of cmake (verified as the latest?). I removed that line altogether from CMakeLists.txt, and it compiled ok.
Furthermore IT RUNS OK, and there is a timebase setting!
I will not close this, as clearly there is a problem with the versions obtained by downloading from the front page..
I am running OpenHantek (version downloaded from main site, as described in another post). FWIW I am using Linux Mint 19.04 on a 32 bit machine, and therefore using GL ES.
I have not found any operating instructions to date, and so may be missing something obvious. However, I have no control over the timebase of the sample whatsoever. This means that you cannot work with anything much below 500 Hz, and presumably not with much higher frequencies either.
As the whole purpose of my exercise has been to analyse the output of an alternator running on a diesel engine operating at 800 rpm to 2500 rpm, I am expecting to see something in the range 80Hz and upwards.
Is there a configuration file or similar structure that I can kludge a suitable value in to get me running, or better still a proper fix? I note that someone referred to a 'spinner' to adjust the timebase not working. This is pretty fundamental, is it not?
I thought it was possible to inspect the frozen sample along its length, but cannot find any such control either.
Is there a more up to date and better working snapshot of the system?
