To Enable Frequency Sweep
Press Sweep at 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). The instrument will generate the sweep waveform from the
corresponding channel (if currently turned on) according to the current
configuration. You can also reset the sweep function menu. Please refer to the
introduction in the following text for details.
Start Frequency and End Frequency
Start frequency and end frequency are the upper and lower limits of the frequency
for frequency sweep. The generator sweeps from the start frequency to the end
frequency and then returns back to the start frequency.
 Start Frequency < End Frequency: the generator sweeps from low frequency
to high frequency.
 Start Frequency > End Frequency: the generator sweeps from high frequency
to low frequency.
 Start Frequency = End Frequency: the generator outputs with a fixed
frequency.
When frequency sweep is enabled, press Start/Center to highlight “Start”.
Notice that, “End” in End/Span will also be highlighted. Use the numeric
keyboard or direction keys and knob to input the desired frequencies. By default,
the start frequency is 100Hz and the end frequency is 1kHz. Different sweep
waveform corresponds to different start frequency and end frequency range.
 Sine: 1μHz to 160MHz
 Square: 1μHz to 50MHz
 Ramp: 1μHz to 4MHz
 Arb: 1μHz to 40MHz
The generator will renewedly sweep from the specified “start frequency” after
start frequency or end frequency is changed.
