This is my first oscilloscope, and my first Quad. Everything has gone smoothly since I got it despite not calibrating and having limited knowledge on o-scopes.
The issue I am having is with the horizonal sensitivity. I had only been in the <4KHz range and using 1mS-50uS. I have just started playing with the >100Khz range and the frequency counter is not showing the correct frequency when using lower HS values. Infact, the frequency is changing everytime I change the HS. It seems to work somewhat with a HS of 200uS, but it not accurate nor is the wave viewable for obvious reasons. With a HS of below 20uS the frequency given is in the 500-700Hz range despite the signal being in the ~24KHz range.
I have looked around the forum and couldn’t find the bug listed as I have seen it but I’m betting it is known. Please let me know if there is a work around for this or if it is being worked on.
I will reply with more of my testing information if the bug is not something thats happening in all units.
