Hello ALL,
This is my first post on this blog, knowingly or unknowingly if I make a mistake pls help me to rectify it
I have got Rohde & Schwarz SML03 Signal Generators - 3nos with problems
one of the problem is horizontal lines on the displays ->LCD's to be replaced
second problem is all the 3 attenuators behaving erratically like,
(1) at 0 dbm output is -17dbm, in one module,
(2) at 0dbm working fine but on negative side behaving erratically like-7dbm=-24dbm, -22dbm=-50 dbm so on 2nd module
(3) difference of -12 to -15 dbm at all levels 3rd module
does anyone have the component layout and schematics for this attenuator module or where can i purchase the same
The module consists of GaAs MMIC SPDT RF switches
Any help is highly appreciated .
