1008C incorrect amplitude
Hi,I'm with a 1008C oscilloscope with the following problem:
The device is showing an incorrect value for the amplitude of a signal, for example, the 2Vpp test signal shows only about 400mV. The shape of the signal looks ok, just the amplitude is wrong. It is not a problem with the compensation output, it's working fine. I tested all inputs with other signals and the problem was the same. The software settings are correct too.
I know it's hard to guess without more details but, do you have any idea of what can cause this kind of problem? Is there any procedure that I can do to test it further?
I found some old threads in the forum with reports of the same issue but, there is no more information in there:

Does all channels have this problem or only channel 1? If only channel 1, something should be burned out.
All channels have the same problem.
