Hi guy´s
Ive been using the old Marconi 2955B testset for several years now and it´s still works like a charm - wonderful piece of machinery..
Lately a problem has occured that i immediatly cant figure out... when you measure output in TX test, the unit doesent immediatly switch over
but hesitates before it engages the relay, you have to tx in to it several times before it reacts...
Also i get a "feedback" noise ="squeeling" when i put power in to it the first few seconds (not the power limit signal ) - then you can hear the relay click and it displays the power/values
Since i dont have any schematics for this thing - anyone that has experienced this problem and can direct me before i take it apart?
""All test ok, everything else works just fine""
Greatful for any ideas
best regards
/ Anders
