To Enable Frequency Sweep


Press Sweep at the front panel to enable 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 specified sweep waveform from
corresponding channel 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 limit 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 knob
to input the desired frequencies. By default, the start frequency is 100 Hz and the end
frequency is 1 kHz. Different sweep waveform corresponds to different start frequency
and end frequency 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 start
frequency or end frequency is changed.
