The DS Instruments TG3000 is a generic tracking generator that can be used with many existing Spectrum Analyzers.
It covers the range from DC to 3GHz. It also functions as a standalone signal generator from 35 to 4400MHz or optionally from 24 to 6000MHz.
The TG3000 can replace the Agilent HP 85640A external TG and add a SG function as well.
