Sweep
DG1000Z can output sweep from a single channel or from dual channels at the same
time. In sweep mode, the generator outputs signal variably from the start frequency
to stop frequency within the specified sweep time. DG1000Z supports linear, log and
step sweep modes, allows users to set start hold, end hold and return time, supports
internal, external or manual trigger source, and can generate sweep output for Sine,
Square, Ramp and arbitrary waveform (except DC).
To Enable Sweep Function
Press Sweep at the front panel to enable the sweep function (the backlight of the
key turns 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 parameters. Please refer to the introduction in the following text for
details.
Start Frequency and Stop Frequency
Start frequency and stop frequency are the upper and lower limits of the frequency
for frequency sweep. The generator always 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 mode is enabled, press Start/Center to highlight “Start”. Notice that
the “Stop” in Stop/Span key will also be highlighted at the same time. 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.

Sine: 1μHz to 60MHz

Square: 1μHz to 25MHz

Ramp: 1μHz to 1MHz

Arb: 1μHz to 20MHz
The generator will renewedly sweep (according to the current new configuration)
from the specified “start frequency” after start or stop frequency is changed.
