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.
