INSTEK spectrum analyzer GSP-827 -6 dBm down than the real value

<< < (3/13) > >>

Adal:
Hi Aurora.

Ok, let me take out the covers and check for damage.   :-BROKE

Somebody has a service manual?
Best regards.

Fraser:
Sadly GW INSTEK service manuals are as rare as hens teeth. I have been in touch with the support team previously and they will not release service information to the public.

KJDS:
You should be able to get an idea of where the issue is from some testing.

If the -6dB is flat across the frequency range then the damage is after the first mixer.

If there is an auxillary IF output you can also check the level there.

Adal:
Unfortunately the GSP-827  don't have a IF out. So I need teardown the thing and looking for damages in the input path.  I take some pictures of my equipment and put here.
Best regards

Adal:
Yes. The -6dBm error are flat across the frequency range
