Available options depend upon Modulation Standard and Modulation Mode
Symbol Rate 1 to 45 Msymbol/s (Standard)
0.132 to 66 Msymbol/s (Extended symbol rate option)
Spectrum roll-off factor 5%, 10%, 15%, 20 %, 25%, 35 %
Spectrum sense Selectable Normal/Inverted
Transmission modes: Modulation on/off
Carrier on/off
Carrier frequency 950 MHz - 2150 MHz in 1 kHz steps
Carrier frequency stability < ±0.02 ppm versus temperature
< ±0.0002 ppm/day ageing after 30 days continuous operation
< ±0.05 ppm/year ageing after 30 days continuous operation
Carrier frequency initial
setting accuracy (ex
factory) ±0.1 ppm max

Phase Noise (discrete
sidebands) <-70 dBc
Spurious outputs
(modulated carrier)
<-60 dBc/4 kHz over the frequency range 500 MHz - 2500 MHz but excluding the
frequency range of the wanted signal (equal to ±1.06 x Symbol Rate about the
carrier frequency, as defined by the spectrum mask Figure A.1 in EN 300 421)
Spurious outputs
(Unmodulated Carrier) <-55 dBc over the frequency range 500 – 2500 MHz, each component
Noise floor (No/C) –120 dBc/Hz for output power levels > –30 dBm
