-====== Phase Noise Measurement ====== 
- 
-  * We measured the phase noise with FSWP from "Rohde und Schwarz". Manual:{{ :groups:mg:fswp_dat-sw_en_3607-2090-22_v0400.pdf |}}\\ 
-  * Information about the measurements is in the ResLab book on the pages 134 - 136 (date: 18.08.2016). 
-  * measurement: 
-         * each device was measured directly behind the output, except it's mentioned 
-         * use SMA-cables instead of BNC-cables if possible, thighten the SMA-plug with an open-end wrench, use golden SMA-I-Connection (better quality) 
-         * don't wiggle the cable -> results in noise in the range of 1Hz - 200Hz 
-         * let the cable swing off bevor starting the measurement 
-         * check before the measurement, if the dBm number isn't too high for the device 
-  * analysis method: 
-         * Program "phasenoise_combined.nb" is located in the AFS 
-         * Copy the program into the folder with the data, which needs to be analyzed and start the program  
-  * physical units: 
-         * dB: epresses the ratio of two values of a physical quantity 
-         * dBc (decibels relative to the carrier): power ratio of a signal to a carrier signal, expressed in decibels(dB) 
-         * dBm: abbreviation for the power ratio in decibels (dB) of the measured power referenced to one milliwatt 
-  
-<hi #ff7f27> - Wie hatten wir gemessen? Was verwendet? 
-  - Klaus Zettel verwenden :-) 
-  - Wie hatten wir die Datei gespeichert? 
-  - Was is dB, dBm, dBc und wie hängt W damit zusammen? 
-  - Frequenzen und dBm-Zahl zu jeder Messung angeben. Gibt es noch andere wichtige Daten in der Datei?</hi> 
- 
-<note important>Beim nächsten mal Messen: klären wie gut die Geräte bei anderen Frequenzen funktionieren? Kabel überprüfen, Frequenzen hinter Originalkabel bis hin zum zum Beipsiel AOM prüfen, Steckverbinder wie BNC-I überprüfen</note>
