Hi,



I have acquired one of the above and unfortunately it has a fault.



The generator functions work OK but the Spectrum analyser and receiver
functions do not detect any signal. When I got it, the analyser worked a
bit but the levels were way off (too low), while watching the display the
trace suddenly became noisy then all the input signal was lost.



I have the 'service manual' but this is repair to module level only.



The self diagnostics tell me that the analyser assy has a 'medium'
probability of being faulty.



Is there any chance of fixing one of these to component level? Do schematics
exist?



Any help would be gratefully appreciated.
