External modulation inputs 1
Modulation types FM, AM, phase mod, pulse mod
Input impedance 50 Ω (nom)
Simultaneous modulation 2
All modulation types (FM, AM,
φ
M and pulse modulation) may be simultaneously
enabled except: FM and phase modulation can not be combined; two modulation
types can not be simultaneously generated using the same modulation source.
For example the baseband generator, AM, and FM can run concurrently and all will
modulate the output RF. This is useful for simulating signal impairments.
1. Option UNT required for FM, AM, and phase mod inputs. Option UNU or UNW required for
pulse modulation inputs.
2. If AM or pulse modulation are on then phase and FM specifications do not apply.
