The DSA800 Series compact and lightweight spectrum analyzers that operate from 9 kHz to 7.5 GHz (1.5 GHz & 3.2 GHz also available). The analyzer adopts a digital IF design that gives it the ability to measure smaller signals and distinguish between small signals by frequency. The IF design enables smaller bandwidth settings which reduce the displayed average noise level. The analyzers have a low phase noise of less than -8 dBc/Hz and a displayed average noise level (DANL) of less than -135 dBm.
