+The '''Tektronix 7L14''' is a 1.8 GHz spectrum analyzer plug-in with digital storage for [[7000-series scopes]].  It occupies three module bays. The biggest difference to the earlier [[7L13]] is the built-in digital storage and averaging.
+The catalog says: ''The [[7603]]/[[R7603]] and [[7854]] are the only oscilloscopes recommended for the 7L14''.
