Carrier Waveform Frequency Range
Sine 1μHz to 160MHz
Square 1μHz to 50MHz
Ramp 1μHz to 4MHz
Arbitrary Waveform 1μHz to 40MHz
After the carrier waveform is selected, you can press Freq/Period to highlight
“Freq”, and then use the numeric keyboard or direction keys and knob to input the
desired frequency value.
To Select Modulating Waveform Source
Press Mod  Source to select “Int” or “Ext” modulating waveform source.
1. Internal Source
When internal source is selected, the modulating waveform is set as a Square
with 50% duty cycle, and the frequency at which the output frequency shifts
between “carrier frequency” and “hop frequency” is determined by “FSK Rate”.
2. External Source
When external source is selected, the generator accepts the external
modulating signal from the [Mod/FSK/Trig] connector at the rear panel.
Note: the [Mod/FSK/Trig] connector is different when controlling FSK
and AM/FM/PM modulations externally. In FSK modulation, the
[Mod/FSK/Trig] connector has adjustable edge polarity.
