Center Frequency and Frequency Span
You can also set the frequency boundaries of frequency sweep through center
frequency and frequency span.
 Center Frequency = (|Start Frequency + End Frequency|) / 2
 Frequency Span = End Frequency – Start Frequency
When frequency sweep is enabled, press Start /Center to highlight “Center”. Notice
that, “Span” in End /Span will also be highlighted. Use numeric keyboard or knob to
enter the desired frequency values. By default, the center frequency is 550 Hz and the
frequency span is 900 Hz. Different sweep waveform corresponds to different center
frequency and frequency span ranges.
 Sine: 1 μHz to 250 MHz
 Square: 1 μHz to 120 MHz
 Ramp: 1 μHz to 5 MHz
 Arb: 1 μHz to 50 MHz
The generator will renewedly sweep from the specified “Start Frequency” after
“Center Frequency” or “Frequency Span” is changed.
Tip
In large range frequency sweep, the amplitude characteristic of the output signal is
subject to alteration.
