Resolution 1 ms
Dual sinewave mode
Frequency range
0.1 Hz to 50 kHz
Amplitude ratio 0 to 100%
Amplitude ratio resolution 0.1%
LF out (internal modulation source)

External modulation inputs
Modulation types
Ext 1
FM, ΦM, AM, and burst envelope
Ext 2 FM, ΦM, AM, and pulse
High/Low Indicator (100 Hz to 10 MHz BW, AC coupled inputs
only) Activated when input level error exceeds 3% (nominal)
Simultaneous modulation
All modulation types may be simultaneously enabled, except: FM
with FM; AM with burst envelope; Wideband AM with I/Q. AM,
FM, and FM can sum simultaneous inputs from any two sources
(INT, EXT 1, and EXT 2.) Any given source (INT, EXT 1, or EXT 2)
may only be routed to one activated modulation type.
