-=== Synthesizer is broken? === 
-Manual for repair: <hi #fff200>TODO WALDEMAR</hi>\\ 
-**Output signal (dBm) is too small:** 
-Probably the amplifier is broken. Check backwards the signal inside the synthesizer with a measuring tip. 
-  - Adjust the frequency of the half from the maximal Oszi-frequency 
-  - Measure the distance between the minimum and maximum sinus-signal. Half of the distance devide by root(2) provide the effective voltage  
-  - Use the data sheet for dBm calculation: {{ :groups:mg:dbm-volts-wattconversion.pdf |}}
