6.1 Select Sweep

Press[Sweep] button on the front panel to enable the Sweep function (the backlight of the key
goes on), and Mod or Burst function will be automatically disabled (if currently enabled).
To avoid multiple waveform changes, enable the sweep mode after configuring the other
parameters (as waveforms and amplitudes of basic waves).
Press [Sweep] button again to close sweep mode.

6.2 Start Frequency and Stop Frequency

The generator sweeps from the start frequency to the stop frequency and then returns back to the
start frequency.
 Start Frequency < Stop Frequency: the generator sweeps from low frequency to high
frequency.
 Start Frequency > Stop Frequency: the generator sweeps from high frequency to low
frequency.
 Start Frequency = Stop Frequency: the generator outputs with a fixed frequency.
When [Sweep] is enabled,pressStart Frequency/Center Frequencysoftkey to highlight the
"Start Frequency".The "StopFrequency" in the Stop Frequency/Frequency Spansoftkey is
also highlighted.Use the numeric keyboard or direction keys and knob to input the desired
frequencies. By default, the start frequency is 100Hz and the stop frequency is 1KHz.Different
sweep waveform corresponds to different start frequency and stop frequency range.For frequency
parameters
of
different
"Specifications".
After modifying the frequency, the generator will restart to output the frequency sweep signalwith
the specified frequency.

6.3 Center Frequency and Frequency Span

Userscan also set the sweep frequency boundaries of the sweep using a center frequency and
frequency span.
 Center Frequency = (|Start Frequency + Stop Frequency|) / 2
 Frequency Span = Stop Frequency – Start Frequency
When [Sweep] is enabled,pressStart Frequency/Center Frequencysoftkey to highlight "Center
Frequency".The "Frequency Span" in the StopFrequency/Frequency Spansoftkey is also
highlighted.Use the numeric keyboard or direction keys and knob to enter the desired frequency
values. By default, the center frequency is 550Hz and the frequency span is 900Hz.Different
sweep waveform corresponds to different center frequency and frequency span range and center
frequency and frequency span are inter-related.
