INSTEK spectrum analyzer GSP-827 -6 dBm down than the real value
<< < (10/13) > >>
KJDS:
When I saw the first plot I thought it possible that one of the secondary LOs had become unlocked, causing the IF to miss the filter, hence the odd shape, but a wider RBW would have shown lower loss and that's not happening.

Unless you can probe down the IF path then you won't work out where the issue is.
Adal:
Ok KJDS.  Thanks for your comment.
Andrew, could you explain me how take apart the covers? I can't take over the covers????
Adal:
All the screw are out, but the cover does not slip. I can't identify the cause. Maybe Andrew can help me
G4JMO:
Hi Adal,
I was initially puzzled by the cover too! ...then I discovered that the carrying handle end caps push off and reveal two more screws. Undo these and then the cover slips off.
Best regards
Andrew
Adal:
Here are the inner's of my spectrum analyzer. The input path and the components that Andrew check first. I will testing tomorrow and let you know
