Modulation types
Ext 1 FM, FM, AM, pulse, and burst envelope
Ext 2 FM, FM, AM, and pulse
LO/HI annunciator [100 Hz to 10 MHz BW, AC coupled inputs only]. Activated when
input level error exceeds 3% [nominal].
Internal modulation source
Provides modulating signal for FM, AM,
pulse and phase modulation signals, and
provides LF output source for basic function
generator capability.
External modulation inputs
