To Set Hop Frequency
Hop frequency is the modulating frequency. The range of hop frequency depends on
the carrier waveform currently selected. Press HopFreq to highlight it and input the
desired frequency value using the numeric keyboard or direction keys and knob.
Sine: 1μHz to 60MHz
Square: 1μHz to 25MHz
Ramp: 1μHz to 1MHz
Arb: 1μHz to 20MHz
To Set Modulating Polarity
Press Polarity to select the “Pos” or “Neg” polarity of the modulating waveform to
control the output frequency.
In internal modulation, set the polarity to “Pos” and the generator would output the
carrier frequency when the modulating waveform is logic low level and output the
hop frequency when the modulating waveform is logic high level. The situation is the
opposite when the polarity is set to “Neg”.
In external modulation, set the polarity to “Pos” and the generator would output the
carrier frequency when the external input signal is logic low level and output the hop
frequency when the external input signal is logic high level. The situation is the
opposite when the polarity is set to “Neg”.
