Sweep

9 Sweep
In sweep mode, the instrument outputs the waveform that changes from the start
frequency to the stop frequency at a specified sweep rate. HDG3000B supports linear
sweep mode.
Users can configure the instrument to output one sweep from start frequency to stop
frequency by applying an external or manual trigger. The instrument can sweep sine,
square, pulse, ramp, Harmonic or arbitrary waveforms (expect DC).

Select Sweep

Press [Sweep] button on the front panel to enable the Sweep function (the backlight of
the key goes on), and
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.

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, press
Freq". The "Stop Freq" in 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 waveforms, please refer to "Frequency
Characteristics" in Specifications.
After modifying the frequency, the generator will restart to output the frequency sweep
signal with the specified frequency.
9.3

Center Frequency and Frequency Span

Users can also set the sweep frequency boundaries of the sweep using a center
frequency and frequency span.
⚫
Center Frequency = (|Start Frequency + Stop Frequency|) / 2
