Built-in preamplifier option for Rigol DSA832, DSA832E, DSA832-TG and DSA832E-TG spectrum analysers.
A preamplifier reduces the displayed average noise level giving better visibility of signals close to the noise floor.
Each licence contains a unique product key. The product key is used to generate a software licence code that must be entered into your instrument. To generate a Rigol software licence code using your Rigol product key, please see HERE. Installed software licence codes are permanent – They are unaffected by Rigol firmware updates.
A preamplifier has been supplied as standard on all Rigol DSA800 series spectrum analysers from 13Apr17. Only Rigol DSA832(E)(-TG) spectrum analysers purchased before this date will require this licence to permanently activate the preamplifier.
