The TSG4100A Series RF Vector Signal Generator offers mid-range?performance and up to 200 MHz modulation bandwidth at an entry-level RF?signal generator price. They use a new technique to provide spurious free?outputs with low phase noise (-113 dBc/Hz at 20 kHz offset from 1 GHz?carrier) and extraordinary frequency resolution (1 μHz at any frequency).The TSG4100A Series comes standard with analog modulation.Convenient, in-field software upgrades allow for easy transition from analog?to more advanced vector and digital modulation capabilities, providing the?most flexible configuration and best CAPEX protection. These instruments?complement other leading mid-range RF test solutions from Tektronix, such?as the USB-based RSA306 Spectrum Analyzer and MDO4000B and?MDO3000 Mixed Domain Oscilloscopes.The TSG4100A Series instruments use an ovenized SC-cut oscillator?(TSG410xA-M00 or E1 models) time-base, providing a 100 X improvement?in stability (and a 100 X reduction in the in-close phase noise) compared to?instruments that use a TCXO time-base.
