I'm currently developing a hopping synthesiser based on a DDS-PLL hybrid. I want to verifying the hopping rate and hopping frequencies of the synthesiser output. Which instrument can be used for this application.
I would also like to know the instruments which are used for measuring the hopping time in GSM systems.
FCA3100 Series & FCA3000 Series of instruments from Tektronix can perform this function, but these are quite new ones. I want to know about those which are traditionally being used in the communication industry.
