Internal modulation See specifications of options.
(Int2, Int3)
External modulation Optimum input level: Approx. 2 Vp–p
(Ext1, Ext2) Input impedance: 600 Ω, BNC connector on the front panel
Coupling: Switchable between AC/DC
AF Output Output signal source Any one out of the internal modulation signal sources (Int1, Int2,
Int3) and external modulation inputs (Ext1, Ext2) can be selected.
Output level 0 to 4 Vp–p
Output level resolution 1 mVp–p
Output level accuracy In Source=Int1 1 kHz:
±(5% of set value + 2 mVp-p)
Impedance 600 Ω, BNC connector on the front panel
Simultaneous Simultaneous modulation, AM depth and FM deviation can be set
modulation independently for all combinations, except for a combination of AM
and pulse modulation.
