To Output Sweep Waveform in DG1000Z

 

DG1000Z can output sweep waveform from a single channel or from dual channels at the same time.
This section introduces how to output sweep waveform from the [CH1] connector.
Date:
Linear sweep type,
the carrier is sine with 5Vpp amplitude,
the frequency range is 50Hz~1kHz,
Sweep Time: 1s,
Internal trigger source
.

 

1. To select output channel

Press CH1|CH2 to select CH1. Now the boarder of the channel status bar is displayed in yellow.

2. To set the carrier waveform shape and amplitude for sweep

1) Waveform: Press Sine to select sine as the carrier waveform.

2) Amplitude: Press Ampl/HiLevel to highlight “Ampl”, and then use the numeric keyboard to input 5.
Then, select Vpp from the pop-up menu.

3. To enable sweep function

Press Sweep to enable the sweep function (the backlight of the key goes on).
 

 When Sweep is enabled, Mod or Burst function will be automatically disabled (if currently enabled).

Int and Sweep will be displayed in the bottom of the screen.

 

4. To select sweep type
 

Press Type to select Linear.


At this point, a white line appears on the waveform in the screen as shown in the right figure.



 
5. To set the start frequency and stop frequency
 1) Start Frequency
 Press Start/Center

 

to highlight “Start”, and then use the numeric keyboard to input “50”. Then, select Hz from the pop-up menu.

2) Stop Frequency
Press Stop/Span

to highlight “Stop”, and then use the numeric keyboard to input 1. Then, select Hz from the pop-up menu.

6. To set the sweep time
Press Sweep Time
 

to input 1 using the numeric keyboard and select sec from the pop-up menu.

7. To select the trigger source
Press Trigger -> Source to select Int trigger source.

9. To enable the output
Press Output1 to turn CH1 output on.
At this point, the backlight goes on and the [CH1] connector outputs the sweep waveform based on the current settings.

10. To observe the output waveform
Connect the [CH1] connector to the oscilloscope using BNC cable. Now, you can observe the waveform via the oscilloscope.
