Abstract
The object is to provide a spectrum analyzer for measuring TDMA wave have wide frequency band and gated sweep function which endures high noise. For this aim, it is constructed comprising, down converter 30 for down converting with predetermined frequency the burst signal which is branched from the input signal f70 inputted to 1st mixer 12 at spectrum analyzer, trigger signal generator 28 for generating trigger signal or gated signal p2 from the down converted burst signal, variable delay circuit 36 for adding integral multiple delay of burst width time or passing the signal which is generated as a trigger signal or a gated signal, and switch S1 for switching the signal on/off to lump voltage generator 21.
